LASER IN SITU KERATOMILEUSIS(LASIK):
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
