LASIK

LASIK stands for laser-assisted in-situ keratomileusis and is a form of surgery aimed at primarily improving the vision of those who are long or short-sighted or who have an astigmatism. The surgery involves the use of Excimer laser to change the shape of the cornea which is the part of the eye that light filtrates to hit the retina. Altering the shape of the cornea allows light to enter the eye differently therefore correcting the patient’s sight deficiency.

The cornea is shaped through once the surgeon has cut a flap in it using either a laser or microkeratome. The surgery itself is painless and lasts only 15 to 30 minutes with most patients resuming normal activities within a couple of days of the surgery.

Types of LASIK Eye Surgery

Wavefront LASIK. Computer imaging provides the surgeon with a three dimensional map of the patients eye. This allows more accuracy with the procedure and a higher chance of the patient obtaining 20/20 vision post-operation.

Standard LASIK. This involves reshaping the tissue of the cornea using a laser. Access to the cornea is obtained by cuttinga flap in the outer layer to allow the laser entry.

Epi-LASIK. Here the surgeon cuts a thin layer from the cornea to allow him or her to reshape it using the laser. Sometimes the layer is replaced or it may be removed completely. The patient is provided with a soft contact lense to allow the cornea to heal unharmed.
