Eye Procedures Using LASIK
Eyesight can be corrected by reshaping the cornea hence altering the way the eye focuses, using laser eye surgery. Laser eye correction can enhance eyesight meaning corrective lenses will not be needed.
A specific technique for vision modification surgery is LASIK eye surgery. LASIK represents laser-assisted in situ keratomileusis. It’s an outpatient medical procedure which uses an excimer laser to treat nearsightedness, farsightedness and astigmatism. In this technique tissue is taken away from the transparent membrane which overlays the iris, known as the cornea. To improve the way the eye concentrates light rays at the rear of the eye, the curvature of the cornea is adjusted.
Laser eye surgery is an uncomplicated process. In order that the surgeon can program the laser with the right prescription, the eye is first of all measured and the cornea is mapped during a pre-surgery examination. During the time of the process, the eye is numbed with eyedrops so there is no discomfort.
A minutely thin flap is cut on the outside of the eye. Then, to modify the contour of the cornea, the laser strips away pre-programmed amounts of cornel tissue beneath the flap with bursts of light. A natural bandage is created by closing the flap back around the eye. No longer than 5 minutes are required for this element of the process.
It typically requires 3 to 6 months for the eyesight to heal fully and vision to become stable, even though theday following LASIK eye surgery you might probably be seeing well enough for light activities and may even be in a position to go back to work. You may need to refrain from strenuous tasks, however, as the eye heals. For most people the eyesight is clear and improved following surgery; for others eyesight may well continue to sharpen as the healing proceeds.
Laser eye correction can have a few temporary, moderate side effects but these normally go away as the cornea mends. These unwanted effects may include some pain or discomfort, dry eye, irritation, hazy or blurry vision, poor night vision, glare or halos around lights, light sensitivity, diminished sharpness of vision, and small pink or red areas around the white of the eye.
