Types of Eye Surgery
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.
