How are LASIK and PRK different?
A. In the LASIK procedure, a microkeratome is used to create a thin cap of corneal tissue. This cap is gently folded back from the surface of the cornea so that the Excimer laser can be used to reshape the cornea for vision correction. The corneal cap is then returned to its original position, adhering quickly without stitches. In the PRK procedure, the Excimer laser is applied directly to the corneal surface for vision correction. To enhance healing, a soft contact lens is worn for two or three days.
