PRK: Surface Laser Vision Correction
What is PRK?
PRK (Photorefractive Keratectomy) is the first generation of laser vision correction and remains a reliable option for many patients.
Unlike LASIK, PRK does not involve creating a flap.
How It Works

An excimer laser reshapes the cornea
03
A protective contact lens is applied during healing
