Laser eye surgery, also referred to as LASIK, can correct vision problems so that patients can avoid wearing corrective lenses or contacts. The cornea, which is the clear front part of the eye, is reshaped during laser eye surgery, changing the focusing power of the eye.
Oversight
The U.S. Food and Drug Administration governs techniques and equipment used for laser eye surgery.
Side Effects
Immediately after the surgery, patients will feel a burning and itching sensation in the eyes. The eyes may tear and water or look red and bloodshot.
Vision
Vision may be blurry for up to 48 hours following the surgery. The eyes will be sensitive to light. Patients often see halos after LASIK surgery. It can take 3 to 6 months for vision to stabilize.
Risks
There is the possibility that too much or too little of the cornea flap is removed, resulting in undercorrections, overcorrections or astigmatisms that can negatively impact vision or require additional surgery.
Time
Laser surgery procedures typically are done on one eye at a time and take approximately 30 minutes to complete.
Results
Doctors at the Mayo Clinic report that eight out of 10 people who undergo LASIK surgery do not need to wear glasses anymore and can expect to achieve at least 20/25 vision.
