Photorefractive KeratectomyRead the Photorefractive Keratectomy article » IntroductionPhotorefractive keratectomy, or PRK, is a type of laser eye surgery used to correct mild to moderate nearsightedness , farsightedness and/or astigmatism . All laser vision correction surgeries work by reshaping the cornea, or clear front part of the eye, so that light traveling through it is properly focused onto the retina located in the back of the eye. There are a number of different surgical techniques used to reshape the cornea. During PRK, an eye surgeon uses a laser to reshape the cornea. This laser, which delivers a cool pulsing beam of ultraviolet light, is used on the surface of the cornea not underneath the cornea, as in LASIK. What Are the Advantages of PRK? PRK is highly accurate in correcting many cases of nearsightedness.

This laser procedure alters the shape of the cornea, which is the transparent front covering of the eye. Though the excimer laser had been used for many years before, the development of LASIK is generally credited to Ioannis Pallikaris from Greece around 1991.
How does LASIK work?During the LASIK procedure, a specially trained eye surgeon first creates a precise, thin hinged corneal flap using a microkeratome. The surgeon then pulls back the flap to expose the underlying corneal tissue, and then the excimer laser ablates (reshapes) the cornea in a unique pre-specified p...
