Term: Photo Refractive Keratectomy (PRK)

« Back to Glossary Index

Surgery in which a small area on the corneal epithelium (surface cells) is polished away. The laser then reshapes the corneal surface in exactly the same way as for LASIK surgery. This differs from LASIK or SBK, which both involve creating a flap that is closed again over the top of the portion of cornea that was reshaped. As a result, PRK patients are prescribed special contact lenses after surgery to promote healing and generally need more time to heal.
