Lasik surgery is a popular alternative for individuals who want to give up their glasses and contact lenses without sacrificing their vision. Doctors at an ophthalmology surgery center Harrisburg PA, will consider the following to determine if you are a candidate for this procedure.
Your Corrective Prescription
Candidates for Lasik surgery vision correction must have a stable prescription that has not changed in at least two years. The degree to which an improperly shaped cornea or lens contributes to nearsightedness, farsightedness and astigmatism is also critical for determining someone’s candidacy for the procedure. For patients whose vision is correctable only with the most potent eyeglass prescriptions, Lasik surgery is not suitable.
Your Eye Anatomy
During Lasik surgery, a surgeon uses lasers to reshape the eye’s cornea. The procedure improves vision by helping light to reach the retina at the back of the eye. A flap cut into the outer cornea provides access for reshaping its interior structure. The flap also serves as a protective layer essential for post-surgical healing. If a cornea is too thin, it is not possible to create this protective layer.
Large pupils can also disqualify patients for Lasik surgery. If pupils dilate beyond the cornea’s surgical site, they can cause light refractions that create undesirable phenomena, including halos, light flashes, and other visual disturbances.
Your Overall Health
Candidates for Lasik surgery must have good overall health to prevent complications and ensure desirable outcomes. For example, patients taking immunosuppressant drugs for auto-immune diseases, including rheumatoid arthritis or lupus, should avoid Lasik eye surgery due to a higher prevalence of post-surgical infection and a decreased ability to heal. Patients with a tendency for chronic dry eyes from medication side effects or Sjogren’s Syndrome are discouraged from undergoing Lasik eye surgery because it can cause dryness.
An experienced ophthalmologist can determine if Lasik eye surgery is a viable choice to improve your vision.
