Laser eye surgery is a procedure for correcting eyesight by reshaping the cornea and modifying how the eye focuses. Laser eye correction can improve vision meaning corrective lenses will no longer be needed.
A particular procedure for eyesight correction surgery is LASIK eye surgery. LASIK stands for laser-assisted in situ keratomileusis. It’s an outpatient surgical procedure that uses an excimer laser to treat myopia, hyperopia and astigmatism. During this technique tissue is taken away from the transparent membrane covering the iris, known as the cornea. To improve the way the eye focuses light rays at the back of the eye, the contour of the cornea is altered.
The process of Laser eye surgery is quite straightforward. Included in the pre-surgery evaluation, the eye is measured and the cornea is mapped, providing the surgeon with the prescription to program into the laser. There is no pain experienced at the time of the process as the eye is numbed with eyedrops.
The surface of the eye is initially cut to provide a minutely thin flap. Through bursts of light, the laser takes away pre-programmed quantities of corneal tissue beneath the flap in order to modify the curve of the cornea. A natural bandage is formed by closing the flap back over the eye. This aspect of the procedure just requires about 5 minutes.
It usually requires three to six months for the eyesight to heal entirely and eyesight to settle down, even though theday following LASIK eye surgery you will probably be seeing sufficiently well for mild activities and might even be set to return to work. While your eye gets better, you may want to stay away from arduous pursuits. For most people the eyesight is sharp and improved right after surgery; for others eyesight may continue to sharpen as the healing proceeds.
There could be a number of short term, mild side effects you get with laser eye surgery but as the cornea gets better these normally subside. Poor evening vision, glare or halos surrounding lighting, light sensitivity, diminished sharpness of vision, small pink or red patches on the white of the eye, hazy or blurry vision, irritation, dry eye, some pain or discomfort are some of the unwanted effects that may be experienced.
