Tell me the difference between photorefractive keratectomy vs radial keratotomy?

In brief: Laser vs scalpel

Prk uses a laser to resurface and reshape the front of the eye to improve vision.
Rk involves creating multiple radial incisions on the cornea in a symmetrical pattern to flatten the cornea. Prk is much newer and more reliable technology. Rk has many side effects such as regression, irregular astigmatism, and scarring.
