Eye surgery, also referred to as ophthalmic or ocular surgery, is a variety of surgical process that is performed on the eye or the encircling tissues. There are a selection of different kinds of eye surgeries including refractive surgery, corneal surgery, glaucoma surgery, cataract surgery, and oculoplastic ( cosmetic ) surgery.
Refractive surgery
The target of refractive surgery is to enhance a patient’s vision. An individual who is either nearsighted or farsighted has a refractive mistake in the interior of their eye. Light entering the eye does not properly target the retina, instead focusing in front of the retina in nearsighted people or behind the retina in farsighted people. The result is that viewed pictures appear blurry and out of focus. Refractive surgery corrects this error, allowing light to focus directly on the retina, thus improving vision and getting rid of the necessity for corrective lenses.
There are countless methods of refractive surgery, the hottest of which are LASIK ( laser helped in-situ keratomileusis ), LASEK ( laser aided sub-epithelial keratomileusis ) as known as Epi-LASIK, PRK ( Photorefractive keratectomy ), CK ( conductive keratoplasty ), and ICRs or Intacs ( Intracorneal rings ).
Corneal surgery
Corneal surgery is any surgery that involves manipulation of the cornea of the eye. This incorporates just about all sorts of refractive surgeries, since the cornea is modified in order to improve the individual’s vision. It also includes corneal transplant surgery, a procedure by which a damaged or diseased cornea is removed and replaced it with a clear cornea from an organ donor. Other sorts of corneal surgery are PK ( penetrating keratoplasty ), PTK ( phototherapeutic keratectomy ), and Pterygium excession.
Glaucoma surgery
Glaucoma is a disease that attacks the optic nerve, leading to loss of vision and a rise in intraocular pressure. Glaucoma surgeries assist to combating the illness by lowering intraocular pressure. This could be accomplished by decreasing the quantity of aqueous produced in the eye or by inspiring the release of excess aqueous humor from the eye.
Cataract surgery
Cataract extraction is the most common eye surgery performed. Age, sickness, or trauma to the eye can often cause the crystalline lens of the eye to become cloudy and opaque. This cloudiness, called a cataract, interferes with the eye’s capability to focus a clear image on the retina, leading to loss of vision. The presence of major cataracts requires the removal and replacing of the lens through cataract surgery. Although there are a variety of different kinds of cataract extraction, the 2 preferred procedures are called ICCE ( intracapsular cataract extraction ) and ECCE ( extracapsular cataract extraction ).
Oculoplastic surgery
Oculoplastic surgery is a sort of eye surgery that concerns the reconstruction of the eye and its surrounding structures. Eyelid surgery, or blepharoplasty, removes OTT fat, muscle and skin from the eyelid to fix sagging or puffy eyes. Browplasty, frequently referred to as a brow lift, is the reconstruction of the forehead and brow bone. Oculoplastic surgery can also involve the removal of the eye itself. Enucleation involves the removal of the eye itself, leaving the muscles surrounding the eye and all orbital contents ready. Evisceration happens when the eyes and all of its contents is removed, leaving just the shell of the sclera prepared.
Eventually, exenteration involves the removal of the whole orbital content. This includes the removal of the eye itself, any extraocular muscles, surrounding fat, and all connecting tissue.
.
Refractive eye surgery is a sort of eye surgery that is used to rectify refractive blunders of the eye and decrease dependency corrective lenses such as eyeglasses and contact lenses. Successful refractive procedures can reduce myopia or nearsightedness, hyperopia or farsightedness, and astigmatism or elongated corneas. A number of difference procedures exist for refractive eye surgery relying on the type and seriousness of the refractive blunder.
There are four main kinds of refractive eye surgery procedures : flap and photoablation procedures, and corneal incision procedures, thermal procedures, and implants.
The most common refractive eye surgeries involve the utilization of laser to reshape the cornea.
Flap procedures involves cutting a tiny flap in the cornea so that the tissue underneath can be reshaped to correct the refractive error. LASIK, short for Laser helped In-Situ Keratomileusis is the hottest refractive surgery and is used to correct myopia, hyperopia, and astigmatism. The LASIK process involves the use of a microkeratome or IntraLase to cut a flap into the stroma, moving the flap out of the way, removing excess corneal tissue with an excimer laser, then replacing and smoothing out the flap. LASEK is most fitted for individual with thin or flat corneas.
The LASEK process uses a small trephine blade to chop into the shallow epithelium, after which the eye is washed in mild alcohol solution to melt the sides of the epithelium. The flap is delicately moved out of the way so that an excimer laser can remove excess corneal tissue, after which the flap is replaced and smoothed out. Epi-LASIK, like LASEK, involves a shallow cut into the epithelium, but makes use of epikeratome to form a thin epithelium sheet for removal rather than the harsher blade and alcohol.
Photoablation, the second stage in flap procedures, employ ultraviolet radiation to remove excess corneal tissue. PRK, or photorefractive keratectomy ( PRK ), was the original laser eye surgery process. PRK involves numbing the eye with local pain-killer eye drops, and reshaping the cornea by destroying miniscule amounts of tissue from the skin of the eye. The laser used, an excimer laser, is a computer-controlled ultraviolet beam of light. It burns cool so as not to warm up and damage the encircling eye tissue.
Corneal incision procedures such as radial keratotomy and arcuate keratotomy use small cuts in the cornea to alter its surface and correct refractive errors. Radial keratotomy, or RK, uses a diamond tipped knife to make a number of spoke-shaped cuts in the cornea. The results of the cuts is the cornea flattens out, minimizing the consequences of myopia. Arcuate keratotomy, or AK, is very like RK. The diamond knife, though, is used to cut cuts that are parallel to the edge of the cornea, as opposed to the spoke-shaped cuts of the RK process. These procedures have been far less common with the rise of laser-assisted refractive eye surgeries.
Thermal procedures use heat to correct temporarily hyperopic refractive blunders, or farsightedness. The thermal keratoplasty procedure involves puts a small ring of 8 or 16 small burns on the eye straight away surrounding the pupil. The appliance of the heat increases the slope of the cornea, making it steeper, thru thermal contractions. There are two main types of thermal keratoplasty. Laser Thermal Keratoplasty, or LTK, is a no-touch process that uses a holmium laser. Conductive Keratoplasty, or CK, uses a high-frequency electrical probe.
The final type of refractive eye surgery, involves the use of implants. Implantable contact lenses, or ICL, can be used for to correct severe levels of myopia, hyperopia, and astigmatism. The implants are actually tiny contact lenses that are inserted thru a tiny incision in the side of the cornea. Implants are seated so that they sit straight away in front of the eye’s natural lens, just behind the cornea. ICL works in association with the eye’s natural lens to refocus light on the retina and produce a crystal clear image.
Each of these procedures has its advantages and drawbacks, and not all individuals are acceptable applicants for refractive eye surgery. Individuals who have an interest in learning more about surgical options should contact their ophthalmologist for more information about these procedures, as well as ask after other new state of the art procedures. Since ophthalmologic surgery is constantly growing and changing with emergence of new technologies and methods, there are always new methods in development. As new kit is developed and strategies refined that can improve the success and minimize the side effects of refractive eye surgery, new procedures will appear to replace outdated strategies.
Since LASIK received approval by the FDA in the early 1990′s, the procedure has grown to become the most widely-performed eye surgery in the united states. LASIK is a surgical process performed on the eye to correct an individual’s vision and reduce dependency on glasses or contact lenses. LASIK stands for Laser-Assisted In Situ Keratomileusis, which literally meaning to’reshape the cornea from inside using a laser’. The process has broad applications to treating refractive errors of the eye and can be employed to treat myopia ( nearsightedness ), hyperopia ( farsightedness ), and astigmatism ( an elongated cornea ).
LASIK works by enhancing the ability of the eye to correctly focus light. In a completely formed eye, light entering the eye bends and directly hits retina, allowing the eye to produce a clear image. The majority of folks, though, have imperfectly formed corneas. Imperfectly formed corneas don’t correctly refract the light on the retina, with the result the viewed image is blurry and deformed. LASIK can correct these refractive mistakes by permanently changing the form of the cornea. Once reshaped, the cornea is in a position to better focus light, eliminating the need for glasses or contacts.
LASIK patients will be given a detailed set of instructions to follow, beginning a couple of weeks before the procedure is to occur. It’s vital that these instructions are followed if the surgery is to be a success . Patients wearing contact lenses will be suggested to stop wearing their lenses anywhere from 2-4 weeks before the process, to give their eyes a change to restart their natural shape. Particular foods, vitamins, beauty products, and medication can also affect the health of your eyes and may want to be evaded prior to LASIK. Failure to follow pre-operative instructions may result in an unsuccessful LASIK process, or the need to fully redo the surgery.
Patients remain awake and alert during surgery, though your health practitioner may give you a mild sedative to help to keep you relaxed and chilled. Numbing eye drops will be applied to the eye to be a local anesthetic. Since the eye’s natural bent is to blink when it has contact with foreign items, it is necessary to secure the eyelids to keep them out of the way of the laser. This is doing using an instrument called a lid speculum. Once the speculum is in place and the eye is cleaned, a tiny ring is placed on your cornea to apply a strong suction to the cornea. This part of the process could be a bit uncomfortable, but the strong suction ensures that you eyes remain immobile thru the remainder of the surgery.
Next a flap is cut into the cornea, leaving a small hinge to keep it attached to the eye. This flap might be made using a tiny, incredibly sharp knife called a microkeratome, or by employing a laser – also called IntraLase. The suction ring serves as a exact guide for the microkeratome to ensure that the flap is formed cleanly and exactly. After the cut has been made, the suction ring is removed and the flap is delicately teased away from the cornea and peeled back ( towards the hinge ) to bare the underlying stroma.
Your doctor will then dry your eye and suggest that you stare at a fixed light, without moving, until the end of the process. Once your eye is in the right position, the excimer laser will be activated. The surgeon will have recently programmed the laser to get rid of the actual quantity of tissue from the exact location ( s ) on your eye prior to the start of the procedure. More severe refractive blunders will require a longer laser treatment, since more corneal tissue will need to be removed. As the laser pulses a beam of light into your eye to get rid of the excess tissue from your eye, you may hear a ticking or zapping sound and may smell an odour similar to that of burning hair. Once the laser has ceased pulsing, your surgeon will replace the corneal flap on your eye and smooth it out to guarantee no surface wrinkles develop.
Since your eye is vulnerable after LASIK, it is critical to take additional cares to protect your eye during the process of healing. Your doctor will give you an eye shield to wear straight after the LASIK process. This shield should be worn while sleeping to hinder you from rubbing your eye and dislodging the flap. The eye shield also stops you from accidentally putting any pressure on your eye. Antibiotic lotion should be used to prevent infection from forming, while eye drops might be used to keep dry and scratchy eye well-lubricated as they heal.
Your doctor will make a follow-up appointment to evaluate your eye within 24-48 hours from the time of your surgery. This will allow him to monitor the healing process, evaluate your eye for any potential problems, and begin accessing the success of the LASIK procedure. After the initial follow-up appointment, you will be asked to return for regular visits every few weeks, then every few months, until such time that your surgeon is confident that the procedure was successful.
Keep in mind that LASIK is not a risk-free procedure and that not all individuals are good candidates for LASIK. If you are interested in finding more about this procedure and if you are a candidate for LASIK, you should contact your ophthalmologist and request an appointment.
When most think about laser eye surgery, they immediately think about LASIK. While it is true that LASIK is a type of laser eye surgery, there are a number of other laser procedures that can produce equally successful results for individuals affected by myopia ( nearsightedness ), hyperopia ( farsightedness ), and astigmatism. In fact, there are really four different types of laser eye surgery : PRK, LASIK, customized LASIK, and LASEK.
PRK, or photorefractive keratectomy, was the process to be approved by the FDA for reshaping the cornea of the eye using a laser. PRK gets use from a specialised cool laser beam, called an excimer laser, to remove excess corneal tissue. The removal of this tissue corrects the shape of the eye so that light entering the eye can be correctly focused on the retina. The outer surface layer of the called, called the epithelium, is removed to expose the underlying corneal tissue. Once this tissue is disclosed, the excimer laser is used to reshape the cornea. The main excellence between PRK and LASIK is that PRK doesn’t make use of a corneal flap. Instead, the epithelium is permitted to steadily heal thru the body’s natural healing process. To protect the exposed cornea, surgeons fit patients with a light-weight contact lens to serve as a bandage for the eye. The contact lens also decreases pain. The lens is usually only worn for a few days, two to three days post-operative, at which time the eye is permitted to heal as normal with no bandage.
LASIK is the most widely known and performed type of laser eye surgery in the U. S. . LASIK stands for Laser assisted In-Situ Keratomileusis, which means to’reshape the cornea from within employing a laser’. LASIK differs from PRK in that a small flap is made in the stroma of the eye. This flap, made by either a microkeratome or IntraLase, is then peeled back to reveal the underlying corneal tissue. An excimer laser is then used to reshape the cornea to fix any refractive errors. Once the cornea has been reshaped, the cornea flap is put back to place and smoothed out. The flap acts as a natural bandage to help the eye heal and protect the delicate cornea. The benefit of LASIK is that the employment of the flap helps the cornea heals more quickly than it would using the PRK strategy, and reduces much of the pain felt during the healing process.
Many ophthalmologic surgeons are now offered the following evolution in LASIK surgery, which they called customized LASIK. The general process used to correct refractive blunders is the same as is employed for normal LASIK procedures, that the addition of wavefront devices used to map the unique surface of the patient’s eye. The wavefront device passes a narrow ray of light through the systems and into the eye, measuring any optical distortions that result as the light exits back out the eye. Any irregularities identified are then fed into the system so that the laser can mechanically correct for aberrations on the surface of the eye. Devotees of customized LASIK claim that the employment of wavefront technology enables surgeons to treat higher order aberrations that can make contributions to low-light visible disturbances like halos and glare not corrected by normal LASIK, eyeglasses, or contact lenses. Customised LASIK can supply patients who suffer from higher order aberrations with a rise in visible lucidity.
The final kind of laser eye surgery is LASEK, or Laser aided Sub-Epithelial Keratectomy. LASEK is especially useful for patients who’ve got a thin or flat cornea, making them debatable candidates for LASIK and customized LASIK processes. During LASEK, a tiny trephine blade is used to cut into the outer skin of the eye, called the epithelium. Once the cut has been made, the eye is washed in a mild alcohol solution to permit the sides of the epithelium to melt. This permits the surgeon to gently tease the epithelium flap out of the way to show the underlying tissue. An excimer layer reshapes the eye under the flap to correct any refractive errors, after which the flap is replaced over the treated cornea. As with LASIK, the replacement of the flap in LASEK speeds up the natural healing process and serves to attenuate pain coming from the process.
Though the final result of PRK, LASIK, customised LASIK, and LASEK is the same – the reduction of refractive blunders – the strategy by which these corrections are made differ. Each procedure has its advantages and drawbacks and is best suited for certain kinds of patients. Individuals who are considering laser eye surgery to correct their vision and reduce dependence on corrective lenses are advised to contact their ophthalmologist to inquire about available options and learn if they are a strong candidate for one of more of these processes.
Eyelid surgery, as called blepharoplasty, is a sort of cosmetic surgery that removes excess fat from the upper and lower eyelids. Age, sickness, and even heredity may lead to puffy or bending eyelids that cause individuals to look tired and worn out. In intense cases, drooping eyelids may even interfere with vision. Eyelid surgery can correct this by removing extraneous fat and trimming flagging skin and muscle tissue. Once the incisions have healed and the swelling has gone down, eyes look rejuvenated, more alert, and youthful.
Choosing a credible surgeon is imperative to a successful surgery. The surgeon you select should be Board Certified and have considerable experience with blepharoplasty. When you have selected a surgeon, the original consultation is vital. Make efforts to bring detailed copies of your medical records, since the doctor will need to complete a medical history. The doctor will perform a close investigation of your eyes and eyelids, including a vision exam, as well as discuss your goals for the surgery. Your surgeon will also use the first consultation to go over the small print of the procedure, the anticipated results, the hazards, and the costs involved.
If you are considering eyelid surgery, it is critical to thoroughly research the process, even if this just means talking over the details with your surgeon. Blepharoplasty is a relatively safe procedure, although like all the other surgeries, you do run the likelihood of issues. When performed by a professional surgeon, complications springing from blepharoplasty are scarce and often minor. Minor complications may include short lived swelling of the eyelids, excess ripping, transient blurred or double vision, tissue love, sensitivity to light, and scarring at the location of the incision. More serious complications include infections and a reaction to the anesthesia utilized in the process. Occasionally patients find that they have problems closing their eyes after blepharoplasty. Most often this is a short lived side effect, though there have been reports of the condition becoming permanent. In rare cases, patients may experience a pulling down of their lower eyelids, called ectropion, that needs further surgical techniques.
Most eyelid surgeries are often performed under a local anesthesia which is used to numb the tissue and muscles around your eyes. Your surgeon may also give you a sedative, either orally or intravenously, to help relax you since patients are kept awake during the process. Under local anesthesia, you will not feel any agony but may experience some tugging or pressure in the op. In certain circumstances, some surgeons decide to perform blepharoplasty under a general anesthetic, in which case, the patient is asleep throughout the whole procedure.
The surgeries typically last from 90 mins to three hours, dependent on how many eyelids are to be corrected. In the procedure, the surgeon makes little incisions along the natural lines of the eyelids – just under the eyelashes on the lower lids and in the deep creases of your upper eyelids. Excess fat is removed trough the incision and drooping muscle and skin are trimmed to neaten your appearance. Once the trimming is completed, your surgeon will use tiny sutures to stitch up the incision.
Once the surgery is complete, your surgeon will advise you on the simplest way to care for the incision. You’ll likely to be told to keep your eyes lubricated with an antibiotic unguent and take pain medication to control any pain you are feeling during the process of healing. Cold compresses can be used to attenuate swelling and bruising though patients will find that even with the compresses the swelling, tenderness, and bruising will be present for a couple of days and will even last up to a month. Your eyes may shiver and feel gummy or dry for several days too. Expect to return for a follow-up visit to your surgeon some days after the procedure for a checkup and removal of your stitches.
Remember that the healing process takes time and it may be several weeks before you are completely recovered. In time, the incisions will become less and less conspicuous, fading into a thin white line which will be barely obvious. The final result of the surgery, though, should be brighter, more cautious eyes that make you look well-rested and young.

The cost of laser eye surgery can alter greatly depending on the sort of surgery to be performed, the patient’s prescription, the equipment used, and the doctor or surgical supplier in question. There are also notable regional differences in the cost of laser eye surgery, with some parts of the US charging higher charges than other regions of the country. Nevertheless, there are several trends in the cost of laser eye surgery that appear to be consistent regardless of the sort of surgery performed, the individual supplier, and the location.
First, all laser eye surgery costs are quoted at a cost per eye. This is thanks to the fact that some patients don’t need surgery in both eyes. Patients who are seeking surgery in both eyes, then, must remember that the price they are quoted will need to be doubled if the surgery is to cover both their left and right eyes.
Another trend shows that laser eye surgery pieces have been rising for the past several years. Technological advances resulting in innovative new apparatus and procedures have increased the success of laser eye surgery and reduced the incidence of complications springing from the process. However, these advances need surgical suppliers to purchase dear new appliances and enroll in costly coaching courses that increase the supplier’s costs. This cost increase is often passed along to the shopper, with the result being a rise in surgery costs. As an example, LASIK procedures using IntraLase technology, a technique in which the corneal flap is created with a laser instead of a microkeratome, generally increases the price tag $250 to $500 per eye. Customized procedures which use wavefront technology to better map the skin of the eye also increase cost.
actually, research has shown that the average state price of laser eye surgery has been rising at a rate of about 15-20% every year for the past 3-4 years. Now, the medium cost for LASIK surgery is $1,800 to $2,000 per eye while LASEK surgery costs between $1,700 – $2,000 per eye and a PRK process will run you between $1,200 – $1,800 per eye.
Laser eye surgery becomes more expensive as the patient’s prescription gets worse. Individuals requiring minor corrections to their sight frequently only require a single passing procedure. Patients with robust prescriptions have a way higher at risk of needing multiple procedures in order to get the specified results, as well having a great risk of complications like visible disturbances. For this reason, many laser eye surgery suppliers charge based primarily on the prescription strength.
As mentioned above, there are regional differences in the cost of laser eye surgery in the united states. Though the medium cost of the procedures varied small from area to area, the diversities between the minimum and maximum charges vary significantly depending on the location in which the surgery was performed.
A study performed by the nation’s publication Review of Ophthalmology, showed that the Southern and Northeastern U.S. Averaged a marginally higher cost for LASIK and LASEK surgeries, at approximately $1,900 – $2,000 per eye, than procedures performed in the Midwest or West, at approximately $1,800 to $1,900 per eye. Yet the Northeast, Midwest, and West regions have large costs ranges. The minimum price per eye in the Northeast was $1,250 while the maximum cost was twice the pricetag at $2,500. Costs in the Midwest ranged from a low of $1,300 per eye to $2,400 per eye. Most shocking though were laser eye surgeries in the West : the lowest cost supplier charged just $900 per eye while the most costly supplier an enormous $2,750 per eye – a difference of $1,850 per eye.
There were little price variations in the Southern United States.
Individuals interested by following laser eye surgery should pay close attention to what costs are included in their supplier’s quote. There is small standardized in the business with regard to how procedures are priced, so patients could find a lower price supplier publicizes a nominal rate only to hit them up for additional fees later on . In the final analysis, the final cost regularly work out to be the same, if not more expensive, than other comprehensive providers.
When interviewing a provider, patients should inquire about the following charges :
apparatus rental charges ( for doctors who hire or lease their equipment )
medicines costs
Follow-up visit costs
Charges for any necessary follow-up procedures or enhancements
Finally, keep in mind that many providers offer financing programs for individuals undergoing laser eye surgery. This may be a solution for some individuals, so patients should be sure to inquire about available options if paying for the procedure in a lump sum will cause financial hardship.
Cataract surgery involves the surgical removal of a lens of an eye which has formed a cataract. Cataract extraction is the one of the most common eye surgery performed and is widely regarded as being one of the safest procedures in the medical community. A cataract happens when the crystalline lens of the eye becomes cloudy or opaque as a result of age, illness, or trauma. This cloudiness can meddle with the eye’s natural capability to direct light and focus an image on the retina. As a result, people with cataracts often experience a loss of vision.
There is no known way to reverse the damage due to cataracts, though the entire removal and replacement of the affected lens with a synthetic lens can restore an individual’s vision. The 2 most common procedures for cataract extraction are called ICCE ( intracapsular cataract extraction) and ECCE ( extracapsular cataract extraction ). Both these procedures are usually done under a local anesthetic on an out-patient basis, so cataract surgery patients are free to go home the same day.
Extra-capsular surgery involves the removal of the affected lens while leaving the bulk of the elastic lens capsule intact. This allows for the direct implantation of an intraocular lens into the lens capsule. Extracapsular surgery may be performed using one of two techniques : conventional ECCE and phacoemulsification. Conventional ECCE involves making a tiny incision into the cornea or the sclera of the eye. The cataract is then manually removed through the incision, so that a replacement intraocular lens can be inserted.
Typical ECCE is best suited for those patients who suffer from extraordinarily hard cataracts or who have got a feeble or thin epithelium covering the cornea. The second strategy, phacoemulsification, employs an ultrasonic handpiece. Ultrasound waves vibrated the cataract, making it crack and break up into a number of little pieces. These pieces are then removed through aspiration thru a little incision in the cornea, after which a replacement intraocular lens can be inserted. Phacoemulsification uses a way smaller incision and might not need stitches, with the result that this procedure regularly affords patients a shorter recovery period.
Intra-capsular surgery involves the removal of the whole lens of the eye including the lens capsule. This process was standard up till the 1980′s in the united states, but is rarely performed in modern medicine thanks to the medical advances in cataract surgery. To remove the lens, the surgeon makes a large incision in the cornea and injects medication into the eye. This causes the zonular fibers that hold the lens in position to break apart and melt. A little probe is inserted into the incision and placed on the lens to that it could be frozen via a cryogenic solution, such as liquid nitrogen. The probe is then withdrawn from the eye, pulling with it the frozen lens. Once the influenced lens has been removed, an intraocular lens implant may be inserted in front of the iris as a replacement. Eventually the incision is stitched up.
Intra-capsular surgery has a high chance of complications because of the pressure that is placed on the vitreous body of the eye during the process. Patients have a prolonged period of healing ( up to 6 weeks ), and are at a high risk for retinal detachment and swelling of the eye. It is for this reason, that virtually all modern cataract extractions are performed thru the extracapsular surgery methodology.
Refractive surgery can be the ultimate solution for some individuals who depend on eyeglasses or contacts to fix their vision. LASIK, LASEK, customised LASIK, and PRK procedures all have the potential to correct refractive errors in the eye that cause myopia ( nearsightedness ), hyperopia ( farsightedness ), and astigmatism ( elongation of the cornea ). However, not everybody with vision problems is a candidate for refractive surgery.
How can you tell if you’re a good candidate? Your best option is to line up an appointment with your ophthalmologist to debate your options. Your health practitioner will conduct an in depth primary exam and take your medical history to figure out if refractive surgery is suitable for you.
There are a number of guidelines, though, that will help you quickly pre-screen yourself to determine if you’ve got the potential to be a refractive surgery applicant.
the perfect refractive surgery applicant :
Is over the age of 18
o The lasers used for refractive surgery aren’t currently authorized for anyone under the age of 18 years.
Suffers from myopia, hyperopia, and/or astigmatism.
Has had a stable eyeglasses or contact lenses prescription for a minimum of the past 2 years.
o A fluctuating prescription indicates that your eyes are still changing. Any procedure performed while your eyes are changing will only result in a short-term improvement in your sight.
Is happy with taking risks .
o Refractive eye surgery isn’t risk free. There is the chance that complications could pop up from the procedure, so if you’re not happy with taking such a risk, refractive surgery isn’t for you.
Has sufficient corneal thickness to permit for the safe completion of the surgery.
o Since refractive surgeries involve the reshaping of the cornea, patients need to have a healthy cornea that’s thick enough to house the procedure. Ask your physician if you meet this criterion.
Isn’t pregnant or nursing.
o ladies who are pregnant are nursing may find that their vision is impacted by hormones present in their system. Until these hormones are flushed out of the body, it is not possible to get a correct reading of the prescription.
Isn’t taking any medications that will cause fluctuations in your vision or meddle with the natural healing process
o Some medication like steroids and retinoic acid may detract from your capability to heal.
Doesn’t have any sicknesses that will meddle in the correct healing of the eye.
o Certain diseases and defects can interfere with the body’s natural healing process. People with autoimmune sicknesses such as lupus or rheumatoid arthritis, immunodeficiencies such as HIV or aids[**] or diabetes might not be good applicants for surgery. Talk with your health practitioner for more information.
Doesn’t actively take part in heavy contact sports like fighting, wrestling, or karate skills.
o Activities that present the chance that you are going to receive a blow to the head or eyes are very dangerous for recent refractive surgery patients.
Doesn’t suffer from ‘dry eyes’.
o Refractive surgery can actually become worse this condition.
Isn’t employed in a profession prohibiting refractive processes.
o Check with your employer.
Doesn’t have corneal scarring.
Doesn’t be afflicted by ocular diseases like cataracts, glaucoma, corneal illnesses or corneal thinning anomalies, or other existing eye illnesses that affect or threaten vision.
o Talk with your doctor for more information.
Although the above rules exemplify the ‘ideal’ refractive surgery applicant, they don’t take rank the standards critical to simply be a’good’ applicants for the procedure. Because you may not meet each single standards above doesn’t mean that you aren’t an acceptable applicant for refractive surgery. Few people meet the rules for the ideal applicant, and only your GP can adequately determine the acceptability of refractive eye surgery as a solution to your visual impairments.
Macular degeneration is an eye disease that affects the macula, located towards the back of the eye, along the retina. The macula is the part of the eye that is responsible for processing light in order to generate sharp, detailed and clear images that are then sent to the brain. Macular degeneration typically does not appear until age 40, and Age-Related Macular degeneration (AMG) typically develops in people aged 55 and older.
Hereditary and Age Appear to be Main Causes
Because of its prevalence among family members, it is believed that genetics play a major role in the development of Macular degeneration. Genetics also plays a role in AMG; however with AMG the simple aging process seems to be the bigger contributing factor.
To date, scientists have identified the gene they believe plays a significant role in the development of Macular degeneration. This gene is called complement factor H (CFH). In addition to this gene, a gene on chromosome 10 called PLEKAH1 is also suspect. Much more study is required to fully understand the roles these two suspect genes play in this eye disease that today strikes 10 million people aged 40 and over.
In the rare cases in which Macular degeneration strikes younger individuals, it is believed that something other than genetics or age leads to a build-up of abnormal blood vessels behind the retina. Myopia and infection are being studied as the causes in these cases.
Other Causes Being Investigated
Several risk factors have also been associated with the onset of Macular degeneration. Smoking is believed to have a significant impact on its development. If you smoke you can add reducing the risk of developing Macular degeneration to the list of reasons why you should quit – now!
Age is a factor in Macular degeneration, too. Rarely is this disease diagnosed in persons under the age of 40. The older a person gets, the greater the chances become that he or she will begin to develop symptoms of this eye disease. Gender is thought to be a factor as well, with females being at greater risk than men. Race plays a role too, with Caucasians being affected much more than African Americans.
More studies are being conducted to determine whether a person’s diet can increase the risks. Early results seem to be suggesting a connection to the onset of Macular degeneration and an increased intake of saturated fats/high cholesterol levels. A decrease in antioxidant levels is cause for concern too. Antioxidants, found in fruits and vegetables, help prevent cells from oxidizing, a process that leads to their ultimate destruction.
Studies are also being conducted to see whether exercise can reduce the risks of developing Macular degeneration. There is belief that keeping blood pressure within “normal” ranges will reduce the risks associated with AMG. Exercise combined with diet is a great way to regulate blood pressure.

What Causes Macular Degeneration?
Macular degeneration is an eye disease that affects the macula, located towards the back of the eye, along the retina. The macula is the part of the eye that is responsible for processing light in order to generate sharp, detailed and clear images that are then sent to the brain. Macular degeneration typically does not appear until age 40, and Age-Related Macular degeneration (AMG) typically develops in people aged 55 and older.
Hereditary and Age Appear to be Main Causes
Because of its prevalence among family members, it is believed that genetics play a major role in the development of Macular degeneration. Genetics also plays a role in AMG; however with AMG the simple aging process seems to be the bigger contributing factor.
To date, scientists have identified the gene they believe plays a significant role in the development of Macular degeneration. This gene is called complement factor H (CFH). In addition to this gene, a gene on chromosome 10 called PLEKAH1 is also suspect. Much more study is required to fully understand the roles these two suspect genes play in this eye disease that today strikes 10 million people aged 40 and over.
In the rare cases in which Macular degeneration strikes younger individuals, it is believed that something other than genetics or age leads to a build-up of abnormal blood vessels behind the retina. Myopia and infection are being studied as the causes in these cases.
Other Causes Being Investigated
Several risk factors have also been associated with the onset of Macular degeneration. Smoking is believed to have a significant impact on its development. If you smoke you can add reducing the risk of developing Macular degeneration to the list of reasons why you should quit – now!
Age is a factor in Macular degeneration, too. Rarely is this disease diagnosed in persons under the age of 40. The older a person gets, the greater the chances become that he or she will begin to develop symptoms of this eye disease. Gender is thought to be a factor as well, with females being at greater risk than men. Race plays a role too, with Caucasians being affected much more than African Americans.
More studies are being conducted to determine whether a person’s diet can increase the risks. Early results seem to be suggesting a connection to the onset of Macular degeneration and an increased intake of saturated fats/high cholesterol levels. A decrease in antioxidant levels is cause for concern too. Antioxidants, found in fruits and vegetables, help prevent cells from oxidizing, a process that leads to their ultimate destruction.
Studies are also being conducted to see whether exercise can reduce the risks of developing Macular degeneration. There is belief that keeping blood pressure within “normal” ranges will reduce the risks associated with AMG. Exercise combined with diet is a great way to regulate blood pressure.

Many people who are dependent on glasses and contacts and want another option. Most of them look into LASIK surgery. It may seem like a great option, but it has its downfalls too. First of all, it’s just what it says: surgery. It requires recovery and is not without complications. Some people are not good candidates for this surgery, or they just don’t want it. Well there are alternatives to having healthy eyes with great vision. When you go to the doctor and ask how to keep yourself healthy, chances are they recommend two things: diet and exercise. Well, if you want to keep your eyes healthy and working properly, the two best options are also diet and exercise.
Just as there are certain foods that improve your physical stamina or your concentration, there are also foods that improve your visual acuity. Eating a diet that’s lacking in these foods may be at least part of the cause of your vision troubles. Most of the nutrients essential to good vision can be found in raw, unprocessed fruits and vegetables. You should remember to eat different kinds of fruits and vegetables because there’s more than one nutrient needed and different nutrients are provided by different foods. Things you should be sure to include are green, leafy vegetables, brightly colored fruits, yellow-orange vegetables, and citrus fruits. You should also try to include some nuts and grains in your diet. You should remember that the more a food is processed, the less nutrients it contains; this includes cooking foods. Also, stay away from saturated fats, but be sure you’re getting enough good fats. Taking a good multivitamin every day can also help fill any nutritional gaps you might have.
The second important ingredient in good eye health is exercise. No, running around the block every day probably won’t help you see better, but there are some specific eye exercises that can. Many of these exercises are based on the principle that if the muscles that control eye movement are kept in good shape, the eye will have an easier time focusing. For vision problems specifically related to eye strain, you should rub your hands together and place them over your eyes. Don’t apply pressure, just rest the balls of your hands on your cheeks and cover the eye area. Keep your hands in this position and breathe deeply for several minutes. This exercise causes the muscles of the eye to relax and focus properly. Another technique is to hold the head still while very slowly rolling your eyes. You should do this several times, alternating directions and resting between revolutions. Doing this helps stretch and strengthen the muscles that control eye movement. You can also stretch these muscles by looking in one direction and pulling the skin around the eye the opposite direction. Do this is each direction (up, down, left and right) several times. If your vision problems are more severe and these exercises aren’t enough, there are specific programs you can purchase that give you lots of specific exercises specifically designed to reduce your dependence on glasses and contacts.
Along with a good diet and daily eye exercises, there are also certain products on the market that are applied around the eye that can help improve eye function. These products usually include a variety of essential oils to help your eyes function properly.
If you follow the steps above given above, you should begin to see more clearly without glasses. You must remember that, unlike glasses, contacts, and surgery, these methods will not work immediately. Just like going on a diet and exercising causes you to slowly lose weight, these methods will gradually improve your vision and overall eye health. So, even if progress is slow, you should stick with it.
