Lasik eye surgery treatment


DEFINITION: Lasik eye surgery is a corrective eye procedure for Myopia , Hypermetropia ,

Astigmatism in which a flap of the corneal surface is raised & a thin layer of underlying

tissue is removed using laser , which reshapes the cornea changing its focussing power .

Lasik has replaced many of the other refractive eye surgery methods. Lasik eye is done with a

computer controlled excimer cold laser & a tool called microkeratome or femtosecond

laser. Surgeon cuts a flap in the centre of cornea to remove a thin layer of tissue , thereby

cornea flattens .The flap is replaced without stitches & reattaches to cornea within



Wavefront guided lasik is advanced method for measuring optical distortions in the eye.

Wavescan can be used to evaluate the eye before surgery. It measures how light is

distorted as it passes into the eye & is reflected back, this creates an optical map of the

eye & show details of the area. This technology lets a lasik surgeon adjust the laser beam

settings for more precise procedure, which gives sharper vision & reduce night vision

He/she should wear comfortable clothing.

Patient should not wear eye make up & ensure all traces of eye makeup are

removed .

Patient should arrange a safe transportation post procedure .

patients post procedure for few hours.
