Laser in-situ keratomileusis (LASIK) is the preferred procedure for correcting farsightedness (hyperopia). It changes the shape of the eye. In LASIK, a thin flap is made on the cornea using a blade or laser. The flap is lifted, and a laser is applied to the central corneal tissue. The laser makes contact with the cornea in a circular pattern around the central optical zone. This changes the profile of the cornea, making it steeper. The laser removes tissue from the cornea very precisely. It doesn't damage nearby tissues. The flap is then replaced, allowing for rapid healing.
LASIK is performed in a surgeon's office or same-day surgery centre. It does not require a hospital stay.
This procedure may not be available in all areas, but it's done in most large cities.
After surgery, you may wear a patch or contact lens on the eye and get a prescription for pain medicine. Someone must drive you home and then back to the surgeon's office the next day. During this second visit, the surgeon will check your eye and prescribe eyedrops to prevent infection and reduce inflammation. More follow-up visits are required, usually the next week and then throughout the first year after surgery.
LASIK usually requires very little recovery time. Most people who have the surgery see quite well the next day. There is little or no pain after LASIK.
LASIK is a procedure done to correct mild to moderate farsightedness in otherwise healthy eyes. It doesn't work as well for severe farsightedness.
Over the short term, LASIK has been shown to be effective and consistent in reducing mild to moderate farsightedness.
LASIK is better at treating lower levels of farsightedness than higher levels.
The risk of complications from LASIK surgery is low and decreases with a more experienced surgeon. Look for a corneal specialist or surgeon who does the surgery often.
Complications and side effects from LASIK may include:
Serious vision-threatening complications are rare but may include:
