4 Reasons to Consider Lasik Eye Surgery
Lasik is not for everyone, but the convenience of not wearing glasses makes laser eye surgery attractive for many people whose eyesight can benefit from the procedure. Talk to your doctor about this surgery to determine if this choice is right for you.
This type of laser eye surgery gives you better eyesight permanently. Surgeons have improved the procedure so much that approximately 96 percent of patients claim they have the desired eyesight following surgery. The surgery corrects vision for people within a certain eyeglass
prescription range. Although you may have to wear glasses some of the time in the future, Lasik corrects nearsightedness, farsightedness and astigmatism.
The surgery lasts 10 to 15 minutes for each eye, and you can go home afterward. The surgeon anesthetizes your eyes with special eye drops, and you receive medication to help you relax. Your doctor creates a flap of corneal matter to reach the tissue underneath. A laser then reshapes the main part of the cornea, and the flap returns to its original place. The cornea holds the flap in place without stitches.
Patients normally experience eyesight correction within 24 hours of surgery. The laser precisely corrects refractive errors within the cornea using computer controls. Each patient's refractory pattern is unique, so your doctor measures each eye to determine how much corneal mass to remove. After the procedure, the eye's length should match more perfectly to the cornea-lens-retina system that produces images for your optic nerve to interpret.
Later in life, doctors may perform the surgery again to give you better vision. The eye naturally adjusts to aging, and candidates for the surgery can have the procedure done more than once. Doctors may also prescribe glasses for certain situations, but the overall effect of your vision improvement remains for years after the surgery.
Who Cannot Have Lasik
Some patients cannot have Lasik eye surgery, according to recommendations made by the U.S. Food and Drug Administration in conjunction with the American Academy of Ophthalmology. Patients must be 18 years of age or older, unless a child has one eye with nearsightedness that could lead to lazy eye. Pregnant or breastfeeding women should not have this surgery because these conditions can change eye measurements. If you take prescription drugs such as Accutane, Cordarone, Imitrex or oral prednisone, you should not have Lasik. Surgeons should not perform Lasik on people with diabetes, rheumatoid arthritis, lupus, glaucoma or cataracts.
People tired of wearing contact lenses or glasses often consider Lasik eye surgery as a way to remove the need for eyewear. The procedure permanently alters the shape of the cornea to improve vision. The cornea, or the clear outer covering of the eye, refracts light so images focus on the retina properly. Read on to discover if you are a good candidate for Lasik eye surgery.
