Anaesthetic drops are used so that you will not feel anything throughout the procedure. A ring is placed over the eye into which alcohol is added for a few seconds. This detaches the outer layer of cells of the cornea allowing this layer to be peeled to one side, exposing the middle layers of the cornea. A computer-controlled laser is then focussed onto the cornea which quickly and painlessly re-shapes the cornea to correct your prescription. The outer layer of the cornea is then replaced and a “bandage” contact lens inserted to protect the cornea while it heals. LASEK can be used to correct long and short sightedness.
