Goodbye glasses Should you consider LASIK?
LASIK eye surgery, the most commonly performed laser surgery, is usually done for better vision.
The surgery often offers improved vision without the hassle of glasses or contact lenses. More than eight out of 10 people who have undergone 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 cutting laser is used to precisely change the shape of the dome-shaped clear tissue at the front of your eye (cornea) to improve vision. During the procedure, you lie on your back in a reclining chair. After numbing drops are placed in your eye, your doctor uses an instrument to hold your eyelids open. Then some laser procedures will be done to make a flap and re-shape your cornea. After the laser procedure, the surgeon lays the flap back into place. The flap usually heals without stitches.
Certain side-effects of LASIK surgery are fairly common like dry eye, glare, halos but a very few people consider them to be a long-term problem.
Under-correction, over-correction or regression may happen after LASIK procedure. But it's rare that surgical complications can result in loss of vision. Rarely, infection or epithelial ingrowth may occur.
Certain health conditions 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 like autoimmune disorders, weakened immune system caused by immunosuppressive medications or HIV, persistent dry eyes, recent changes in vision due to medications, hormonal changes, pregnancy, breast-feeding, inflammation of the cornea, lid disorders, eye injuries or eye diseases such as uveitis, glaucoma or cataracts.
LASIK surgery is usually not advisable if patients have an eye disease that causes the cornea to thin and bulge, or if they have a family history of it, have fairly good overall vision, have severe nearsightedness, have very large pupils and have age-related eye changes that cause vision to be less clear.
