LASIK (Laser-Assisted-In-Situ Keratomileusis) is currently one of the most frequently performed elective procedures in North America. It is a highly effective outpatient procedure that is suitable for most low, moderate and higher prescriptions. LASIK uses a cool beam of light from the excimer laser to gently reshape the front surface (cornea) of your eye. This is a surgical operation where a flap of surface cornea is cut and rolled aside in order that a laser beam can remove internal tissue from the inside (stroma or body) of the cornea. Following removal of tissue the surface layer is reattached. The amount and shape of the removed tissue is determined by the pre-operative refractive error i.e. myopia hyperopia or astigmatism.
Sensitivity to light usually disappears in a couple of days. Blurred vision or visual distortions occur in some patients but usually disappear within several weeks and up to 3 months.
