Things to Know Before Getting LASIK Surgery lasik durham nc, nearsightedness and astigmatism, Existing eye

Millions of Americans wear glasses or contacts to correct vision problems like farsightedness, nearsightedness and astigmatism. However, both options do have downsides: glasses can fall off during strenuous activities, while contacts can be complicated to put on. Many of those who suffer from some degree of vision impairment certainly welcome other ways to get vision correction.

In recent years, LASIK surgery has become the answer to that need. In this procedure, lasers are used to remove tiny parts of the cornea to correct the latter’s shape, thus leading to improved eyesight. Before getting the procedure, however, you need to check if you meet the conditions of a suitable candidate.
Good Health
As in all surgeries, even minor ones like LASIK, patients should ideally be in good health to avoid complications. If you have untreated diabetes, autoimmune diseases or collagen vascular ailments, LASIK surgery might not be for you.

Other Eye Problems
Existing eye problems like strabismus (muscle imbalance) or amblyopia (lazy eye) can affect the surgery’s success and impede healing, so make sure to disclose all eye conditions to your doctor before the procedure.

Break from Wearing Contacts?

Prior to surgery, your doctor will map out your cornea’s shape to determine how much to remove. However, wearing contact lenses for prolonged periods can change your cornea’s shape and throw off the measurements. To avoid this, you’ll be asked to stop wearing contacts and allow your cornea to return to its original shape prior to the surgery.
