What is it?
Radial keratotomy utilises a very fine diamond surgical blade in order to make several radial incisions along the outermost layer of the cornea, the front surface of the eye. These incisions alter the shape of the cornea so that light refracts correctly on the retina. While laser surgery is quickly becoming the norm, some conditions are more appropriately treated with this older procedure.

Under a microscope, the doctor will make the incisions on the surface of your eye. The incisions usually follow a wheel-spoke pattern. The cuts weaken the outer layer of the cornea, and the pressure from inside the eye causes the weakened spots to arc or bend, thus reshaping the cornea and correcting the vision.

Recovery time:
1 to 2 days.
