involves the use of a computer to measure the shape of the cornea. Using these measurements, the surgeon applies a computer-controlled laser to make modifications to the cornea
Photorefractive keratectomy.
The PRK procedure flattens the cornea by vaporizing small amounts of tissue from the cornea's surface. Photorefractive keratectomy can be used to treat mild to moderate forms of myopia.
PRK stands for photorefractive keratectomy.

three types of corrective surgeries available as of 2001: 1) radial keratotomy (RK), 2) photorefractive keratectomy (PRK), and 3) laser-assisted in-situ keratomileusis (LASIK).

To correct myopia, several surgical procedures can be performed, including LASIK (Laser-Assisted In Situ Keratomileusis), PRK (Photorefractive Keratectomy), and SMILE (Small Incision Lenticule Extraction). LASIK and PRK involve reshaping the cornea with lasers to improve light focus on the retina, while SMILE uses a minimally invasive technique to remove a small piece of corneal tissue. Each procedure has its own benefits and considerations, and the choice depends on factors like the severity of myopia and the patient's eye health. Consulting with an eye care professional is essential to determine the most suitable option.
A superficial keratectomy is the usual treatment. Under local anesthesia the nodes are scraped from the cornea. Pain varies from patient to patient, but the outcome is generally good.
