Anaesthetic drops are used so that you will not feel anything throughout the procedure. A special device is used to create a very thin flap in the cornea. The flap is peeled back to expose the middle layers of the cornea. A special computer-controlled laser is then focussed on the exposed area. This quickly and painlessly re-shapes the cornea to correct your prescription. The flap is then carefully replaced and heals naturally. Drops may be used for a few days after treatment to minimise the risk of complications. LASIK is a type of laser surgery designed to correct short and long-sightedness.
