Refraction - The bending of light rays. To have clear vision, the eye must focus light rays on the retina, which means bending them as they enter the eye. Two structures in the eye perform refraction: the cornea and the crystalline lens.

DSAEK - DSAEK (Descemet's Stripping Automated Endothelial Keratoplasty) is a new procedure devised in 2007 for improving a corneal transplant. Descemet's Membrane (named after French physician Jean Descemet (1732-1810), is the basement layer, the innermost of the cornea's five layers. DSAEK transplants only this very thin layer rather than the entire cornea. The replacement layer from a donor stays in place without the need for any sutures. Recovery from DSAEK is one to three months, as compared to the one to two years' recovery required by a full corneal transplant.

: Photorefractive Keratectomy (PRK) - A refractive surgery like LASIK, where an excimer laser is used to reshape the cornea and correct myopia, hyperopia and astigmatism. It’s used for those who have corneas too thin to tolerate a LASIK procedure. Instead of the microkeratome being used to create the corneal flap, the laser is used, which can do it even more precisely and subtly than the microkeratome.
