LASIK Eye Procedures
Vision can be corrected by reshaping the cornea therefore altering how the eye focuses, using laser eye surgery. Laser eye correction can improve eyesight so that corrective lenses will no longer be required.
A particular procedure for vision modification surgery is LASIK eye surgery. LASIK stands for laser-assisted in situ keratomileusis. It is an outpatient surgical procedure which uses an excimer laser for treatment of nearsightedness, farsightedness and astigmatism. Tissue is taken away from the cornea, the clear membrane which covers the iris. The contour of the cornea is adjusted to improve how the eye focuses light rays at the back of the eye.
The process of Laser eye surgery is quite simple. As part of the pre-surgery examination, the eye is measured and the cornea is profiled, supplying the surgeon with the prescription to program into the laser. At the time of the procedure, the eye is anesthetized with drops so there is no discomfort.
A microscopically thin flap is cut on the outside of the eye. Then, to modify the contour of the cornea, the laser takes away pre-programmed amounts of cornel tissue below the flap with bursts of light. A natural bandage is formed by closing the flap back over the eye. No longer than five minutes are needed for this element of the process.
It generally requires 3 to 6 months for the eye to heal totally and eyesight to stabilize, though theday following LASIK eye surgery you will probably be seeing sufficiently well for mild activities and may even be set to return to your job. As your eye heals, you may need to stay away from rigorous activity. Also your eyesight may continue to sharpen as the recovery proceeds, though for most people the eyesight is clear and improved soon after surgery.
Laser eye correction can have a number of short term, moderate side effects but these normally disappear as the cornea mends. These side effects may include some soreness or discomfort, dry eye, scratchiness, hazy or blurred eyesight, bad night vision, glare or halos surrounding lamps, light sensitivity, diminished sharpness of vision, and small pink or red spots around the white of the eye.
