Laser eye surgery is a procedure for correcting vision by reshaping the cornea and modifying the way the eye focuses. Laser eye correction can enhance vision so that corrective lenses will not be required.
LASIK eye surgery is one technique of eyesight modification surgery. The acronym LASIK is short for laser-assisted in situ keratomileusis. Nearsightedness, farsightedness and astigmatism can all be treated by this outpatient medical procedure which uses an excimer laser. Tissue is taken away from the cornea, the transparent membrane which overlays the iris. To improve how the eye concentrates light rays at the rear of the eye, the curve of the cornea is altered.
The procedure of Laser eye surgery is quite uncomplicated. In order that the surgeon can program the laser with the optimum prescription, the eye is first measured and the cornea is charted during a pre-surgery assessment. During the time of the procedure, the eye is numbed with eyedrops so there is no pain.
A minutely thin flap is cut on the surface of the eye. By means of bursts of light, the laser strips away pre-programmed quantities of corneal tissue below the flap so as to change the curvature of the cornea. A natural bandage is formed by closing the flap back over the eye. No more than five minutes are necessary for this part of the procedure.
It commonly requires 3 to six months for the eye to heal entirely and vision to become stable, although theday following LASIK eye surgery you might possibly be seeing well enough for mild pursuits and may possibly even be set to go back to work. As your eye heals, you may want to stay away from rigorous tasks. Also your vision may continue to sharpen as the healing proceeds, though for most people the eyesight is clear and improved soon after surgery.
There may be a number of short term, mild adverse reactions that come with laser eye surgery but as the cornea heals these usually disappear. These adverse reactions may include some soreness or discomfort, dry eye, scratchiness, hazy or blurred eyesight, poor night vision, glare or halos surrounding lights, light sensitivity, reduced sharpness of vision, and small pink or red patches on the white of the eye.
