LASIK can be used to treat myopia (nearsightedness), hyperopia (farsightedness) and astigmatism.
LASIK is performed wih the help of the numbing drops and takes a total of 10 minutes for both eyes. During LASIK, the outermost layers of the cornea are peeled back using an automated blade called a microkeratome. This creates a hinged flap which is lifted back, exposing the corneal tissue beneath. The cornea is then precisely sculpted by the excimer laser into a new shape to correct the vision. The flap is set back in place.
Just after LASIK, you experience tearing, light sensitivity, pain and blurred vision for 3 to 4 hours. Later, the discomfort in the eyes is gone and the vision is improved. Next day, your eyes are checked. Eye drops are used for a week after LASIK.
Of 100 myopic persons who undergo LASIK, more than 90 percent would be glasses-free.
