What You Should Know About LASIK Eye Surgery to Improve Your Eyesight

LASIK surgery is a safe solution for anyone suffering from common refractive eye issues. While the procedure is completely safe, patients may avoid LASIK due to misconceptions or false information. Instead of putting off this helpful procedure, you should learn more about LASIK and how it really works.

LASIK Surgery Is Intended to Treat Refractive Errors

If you suffer from near-sightedness (myopia), far-sightedness (hyperopia), or astigmatism, you may be a candidate for LASIK in San Antonio. These eye conditions are referred to as refractive errors and are caused by the shape of the cornea.

Refractive errors impact the way your eye focuses, possibly requiring the need for glasses or contact lenses. LASIK surgery treats refractive errors by altering the shape of the cornea and allowing the eye to properly focus for clearer vision.

You Require an Eye Exam Before Getting LASIK Surgery

Your eye doctor must first determine if you are a suitable candidate for LASIK eye surgery. During a thorough eye exam, the eye doctor looks at the shape of your cornea. Doctors also look for the presence of any other eye issues, the moistness of your eyes, and pupil size. Patients who wear contact lenses are generally advised to stop wearing the contacts for about two weeks before the exam and the procedure.

The Procedure Only Takes 10 to 20 Minutes Per Eye

You may be surprised to learn that the procedure typically only takes 10 to 20 minutes per eye. Before the procedure, the eyelids are held open with an instrument called a lid speculum. A small flap is created on the surface of the eye and folded back to uncover the cornea.

Using a specialised laser instrument, the doctor reshapes the cornea. The cornea is flattened for near-sighted people, while far-sighted patients receive a steeper cornea. The flap is then unfolded and positioned over the corneal tissue. There are no stitches or bandages and the eyes naturally heal within several days.

Most Patients Have 20/20 Vision After the Surgery

Treating refractive errors, LASIK surgery helps patients achieve 20/20 vision. While the cornea heals quickly, it can take several weeks for a patient’s vision to fully recover and experience the full effects of his or her reshaped cornea.

The changes to your cornea do not prevent future eye conditions. As you age, you may still develop a loss of near vision.

Depending on your existing vision, you may still need to wear contacts or glasses. However, you should require a lower prescription level. Patients with mild refractive errors may eliminate the need for contacts or glasses.

If you want to enjoy 20/20 vision, consider getting the LASIK procedure. These surgeries have a high success rate and the recovery time is short. Talk to your eye doctor to schedule an exam and determine if you are a suitable candidate for LASIK.
