Surgery often provides improved vision without the hassle of glasses or contact lenses. More than eight in ten people who have had LASIK refractive surgery no longer need to use glasses or contact lenses for most of their activities.

LASIK surgery is usually completed in 30 minutes or less.
During LASIK surgery, a special type of laser cutting is used to precisely alter the shape of the clear, dome-shaped tissue in the front of the eye (cornea) to improve vision. During the procedure, you lie on your back in a recliner chair. After placing numbing drops in your eye, your doctor uses an instrument to hold your eyelids open. Then, some laser procedures will be done to flap and reshape your cornea. After the laser procedure, the surgeon puts the flap back in place. The flap usually heals without stitches.
Some side effects of LASIK surgery are quite common like dry eye, glare, halos, but very few people see them as a long term problem.
Under-correction, over-correction, or regression can occur after the LASIK procedure. But it is rare that surgical complications can lead to vision loss. In rare cases, infection or epithelial growth may occur.
Certain health problems can increase the risks associated with LASIK surgery or make the outcome less predictable.
Doctors may not recommend laser refractive surgery if the patient has certain conditions such as autoimmune disorders, a weakened immune system caused by immunosuppressive drugs or HIV, persistent dry eyes, recent changes in vision due to drugs, hormonal changes, pregnancy, breastfeeding, inflammation of the cornea, eyelid disorders, eye damage or eye diseases such as uveitis, glaucoma or cataracts.
LASIK surgery is generally not advised if patients have eye disease that causes thinning and bulging of the cornea, or if they have a family history, have fairly good overall vision, have severe myopia, or have severe myopia. very large pupils and have eye changes that make vision less clear.
