Correct Refractive Error Eye Surgery
Eye surgery, also called ocular surgery, is usually surgery performed upon the eye itself, or either its adnexa or the lens itself. The eye, a very delicate organ, needs extreme care prior, during, and immediately after a surgery to avoid or minimize further harm to the eye. The risk of eye damage greatly depends upon the patient’s past medical history, as well as his or her age, overall health, previous eye problems, etc. The common problems that can cause damage to the eye are glaucoma, cataract, vitreous hemorrhage, retinal detachment, or even eye cancer. It is not uncommon for people to have vision problems at some point in their lives and to be under-treated for these conditions.
One common eye surgery which many people undergo is called cataract surgery. Cataract is a disease caused by excessive build up of moisture on the eyes, or the “queer” tissue, which lies between the eyeball and the iris. Excessive buildup of water results in cloudy, hazy vision, due to the loss of nutrients and moisture from the eye, which in turn causes the iris to close.
Another eye surgery that can correct refractive error is called myopia, or nearsightedness. Myopia is the result of an imperfectly shaped cornea, or a lack of curvature in the lens of the eye, which causes light rays to reflect off of certain portions of the retina, resulting in blurred vision. Myopia can be corrected through glasses, contact lenses, or surgery. If it cannot be corrected by glasses, then myopia can also be corrected through the use of myopia correctors such as Bifocal Contact Lenses.
