Eye surgery, also known as ocular surgery, is surgery performed on the eye by an Ophthalmologist.
A cataract is an opacification or cloudiness of the eye’s crystalline lens due to aging, disease, or trauma that typically prevents light from forming a clear image on the retina. Cataracts can cause blurry vision and increase the glare from lights. If a cataract makes it difficult for you to carry out your normal activities, your doctor may suggest 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.
A pterygium is a growth of the conjunctiva or mucous membrane that covers the white part of your eye over the cornea. The cornea is the clear front covering of the eye. This benign or noncancerous growth is often shaped like a wedge. It occurs more often in people who live in warm climates and spend a lot of time outdoors in sunny or windy environments. Common symptoms include redness, blurred vision, and eye irritation.
The pterygium surgery is a minimally invasive surgery. It is performed to remove noncancerous conjunctiva growths (pterygia) from the eye. Once the pterygium is removed, it will be replaced with a graft of associated membrane tissue to prevent recurrent pterygium growths.
Surgery involves either laser treatment or making a cut in the eye to reduce the intraocular pressure (IOP). The type of surgery will depend on the type and severity of your glaucoma and the general health of your eye.
Surgery can help lower pressure when medication is not sufficient. However, it cannot reverse vision loss.
During laser surgery, a focused beam of light is used to treat the eye’s trabecular meshwork (the eye’s drainage system). This helps increase the flow of fluid out of the eye.
In contrast, incisional surgery (also called filtering surgery) involves creating a drainage hole with the use of a small surgical tool. This new opening allows the intraocular fluid to bypass the clogged drainage canals and flow out of this new, artificial drainage canal.
