Lasik

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.

The procedure takes 10 - 15 minutes and is usually performed under topical anaesthetic which may be accompanied by an oral sedative for relaxation.
