Our Services Photo Refractive Keratectomy (PRK)

What is PRK?
PRK (Photo Refractive Keratectomy) is a refractive surgery to correct low to moderate myopia and astigmatism. For corrections of less than -8.0 dioptres, PRK is highly accurate and the effect is permanent. PRK involves a procedure in which the surface of the cornea is reshaped using an excimer laser. As the corneal curvature is changed, the light rays will focus on the retina to form a sharp image. With the modern technology advancement, PRK is rarely performed except in special cases.

The advantages of LASIK over PRK are minimal postoperative pain, a faster recovery and the larger range of refractive errors that can be treated effectively.
