WHAT IS LASIK?
LASIK (Laser assisted in-situ keratomileusis) is one the most popular laser vision correction procedures, with more than 28 million LASIK procedures performed worldwide to date.
A corneal flap is created using a femtosecond laser or mechanical microkeratome. If the femtosecond laser is used to create the flap, then the procedure is considered ‘Bladeless’.
The corneal flap is folded back to expose the underlying corneal bed and to allow excimer laser ablation to occur. Laser excimer ablation is necessary to reshape the corneal surface so that refractive errors can be treated. The flap is then replaced back into its natural position and smoothened. LASIK is performed with numbing eye drops only and both eyes are usually treated at the same time. The entire process may take around 20-30 minutes.
Typically, visual recovery occurs in the first week following surgery and the eye may feel irritated for a day or so only. Medicated eye drops are prescribed for 1 week afterwards. There is usually little down time after LASIK and patients are able to participate in most activities with the exception of water sports for the first month.
