Lasik is the world’s most popular procedure to remove spectacle powers upto -9D or +5D permanently. It can be done after 18 years of age, once the spectacle power stabilises. With proper pre-operative investigations and case selection, it is a safe procedure, which gives almost immediate effect. In Lasik, a flap is made in the cornea and the shape of the corneal bed is altered with excimer laser to enable proper focusing of light. The flap is then replaced.
Advanced Surface Ablation (ASA):
In this procedure instead of cutting the flap, corneal epithelium is removed with help of excimer laser itself using streamlight technology. Then the spectacle number is corrected in the same flow. Bandage contact lens is applied for period of 3-4 days till epithelium heals. This procedure has advantage that there is no long-standing weakness in corneal layers. This is a preferred procedure for lower myopia.
Refractive surgeries are done using state of the art FDA approved Alcon Wavelight EX 500 Lasik Machine, which is extremely fast and has eye tracking system to prevent errors due to eye movements. The technology of this machine also minimises side effects like post-operative haloes. It uses Morea
SBK II microkeratome, which can make corneal flaps as thin as 90 microns and of quality equivalent to Femto second laser. This is complemented by The Alcon Oculyzer II, which does accurate pre-operative analysis of the cornea, to ensure proper case selection and minimise post-operative complications or surprises. Post-operative pain is minimal and patient can resume normal activities within a week. The chances of recurrence of small spectacle power after properly done Lasik is only 1-2%.
