Defining Lasik Eye Surgery - How It Works
In general, common refractive errors, such as nearsightedness, farsightedness and astigmatism are caused due to the irregularities of the corneal surface. These anomalies can be corrected by reshaping the cornea. LASIK procedure makes use of an advanced laser called excimer, which is an ultraviolet chemical laser. The laser is controlled by sophisticated computer software. The computer-controlled sensors measure the eye position a few thousand times per second, and then redirect the laser to make precise incisions in the cornea. The reshaped cornea allows for the desired refraction and therefore results in enhanced visual acuity.
Conventional LASIK procedure makes use of a microkeratome, a d...
