In this light rays from excimer laser is focused on the corneal surface. This
vaporizes corneal tissue and changes its curvature. This is all controlled by sophisticated computer. Thus the power is reduced.
Disadvantages
Recovery period is longer than lasik
procedure. It may take 5 – 6 months for stabilization of vision and may be a year
Recommended to correct upto 8 dioptre only.
May
cause corneal scarring resulting in glare and reduced vision.
