PRK was the original form of laser eye surgery and remains an important treatment option today. Unlike LASIK, no corneal flap is created. Instead, the surface layer of the cornea is carefully removed before the laser reshapes the underlying tissue to correct vision.
In this video, Dr Glenn Carp explains how PRK works, why the laser is applied to the surface of the eye and how each stage of the procedure is performed. Clear diagrams guide you through the treatment from beginning to end. Although recovery is usually slower than with LASIK or SMILE, PRK can be particularly suitable when corneal measurements, lifestyle or other individual factors make a surface-based, flap-free treatment preferable.
