How is Lasik laser performed?
Lasik involves extensive computer analysis of the eye. The spectacle user is then asked to come on the scheduled day for the laser treatment. Local anaesthetic eye drops are instilled in the eye to achieve a pain free procedure. The patient is now made to lie under the laser machine and asked to fix his gaze at a red light. The data of the patient is fed into the computer memory of the laser. A special machine called the microkeratome is used to pick up a thin corneal flap of 160 microns (equivalent to an onion skin). Laser is delivered to the cornea under this flap to correct the spectacle number. It takes 20 to 60 seconds to complete the laser delivery to one eye. The corneal flap is placed back in position where it holds strongly within two minutes due to its natural bonding properties. The entire procedure takes about 10 minutes.
