PRK Laser Eye Surgery
CK | Crystalens | PRK | EpiLASIK | LASEK | ALK
PRK is a laser eye surgery procedure that treats nearsightedness, mild to moderate farsightedness and astigmatism by flattening the center of the cornea with cool beams of ultraviolet light. Based on the patient’s individual refraction, the computer generates an accommodating amount of laser light to remove a calculated amount of corneal tissue. The laser eye surgeon uses an excimer laser to remove tissue from the surface of the cornea, allowing the cornea to focus light correctly. For nearsighted people, the doctor will perform PRK to flatten the too-steep cornea. For farsighted people, the doctor will use the laser to create a steeper cornea. Following PRK, vision begins to improve around three days following the treatment and steadily improves.
Advantages of PRK
- Absence of potential flap complications
- Quicker (about 30 seconds per eye) than LASIK
- Slightly less expensive
- Consumes less corneal tissue than LASIK
PRK is Well Suited For:
- Patients with mild to moderate myopia or hyperopia.
- Patients who cannot have a cut flap, such as pilots, athletes, or those involved in other activities or occupations where the possibility of contact with the eye is probable.
- Patients who are not good candidates for LASIK due to corneal shape or thickness
