Laser Vision Correction

Other Refractive Surgeries
Although LASIK is the most common refractive surgery performed for most people, there are occasions when other surgical methods may be more suitable.

PRK
PRK (Photorefractive Keratectomy) is the original excimer laser vision correction procedure. Since it was developed in the late 1980s, over one million PRK surgeries have been performed worldwide. PRK differs from LASIK in that no flap is made. The surgeon simply removes the cornea's outermost epithelial cell layer. The excimer laser then removes microscopic amounts of tissue from the corneal surface. PRK is effective at correcting low to moderate levels of myopia, but vision can take up to six months to stabilize and pain or discomfort are more common post-operatively than with LASIK.
