Eye surgery is surgery performed on the eye and its appendages by an ophthalmic surgeon. Ocular surgery can be performed for several condition.

Eye surgery preparations and precautions : For optimal safety the ophthalmic surgery is performed in a clinic, with a medical and paramedical team. The operation is usually performed under local anesthetic for the more benign procedures. General anesthetic is used in the treatment for children and in cases of severe traumatic injuries

Several types of surgery : The ophthalmic surgeon can perform several types of surgery, depending on the pathology to be treated. Cataract surgery will replace the opaque lens with an artificial lens. Glaucoma surgery is used to lower intraocular pressure. Refractive surgery corrects refractive errors in the eye, such as keratoplasty, keratotomy or presbyopia inversion. One can also find corneal surgery. For example, vitreoretinal surgery to correct retinal detachment. Finally, eye muscle surgery will correct vision defects such as strabismu.

pterygium surgery

It’s best to approach pterygium surgery with the goal of reducing the chances of recurrence at all costs. While most pterygia are asymptomatic and regarded as garden variety lesions, they become serious problems if they recur after removal. These cases most certainly warrant a subspecialist evaluation. In this article, I’ll discuss some surgical approaches to pterygium, with particular emphasis on recurrent pterygium.

There are many different ways to do a basic pterygium removal, and potentially hundreds of modifications of the surgical technique. The most common method of simple excision takes about five minutes but is associated with a much higher relative risk of the pterygium recurring. For this technique, you simply pry the scar tissue off the cornea and snip it off. It’s effective for about 90 percent of cases, but that means you can expect approximately 10 percent of cases to recur (often with a vengeance).

As a medical adjuvant to the simple snip excision, one might also consider the adjunctive use of antimetabolites such as mitomycin-C on the surgical site. This isn’t something that I usually do however, because mitomycin carries the risk of scleral melting. If you’re concerned enough to pour chemotherapy on the surface of the eye to prevent the pterygium from coming back, then, rather than using the mitomycin technique, the optimal thing to do would be to try the PERFECT technique.



Cataract surgery

Cataract surgery is a procedure to remove the lens of your eye and, in most cases, replace it with an artificial lens. Normally, the lens of your eye is clear. A cataract causes the lens to become cloudy, which eventually affects your vision. Cataract surgery is performed by an eye doctor (ophthalmologist) on an outpatient basis, which means you don't have to stay in the hospital after the surgery. Cataract surgery is very common and is generally a safe procedure.
