Photorefractive Keratectomy (PRK)

PRK is a laser eye surgery that reshapes the cornea’s surface without creating a flap, making it suitable for individuals with thinner corneas and offering an alternative to traditional LASIK.

What Is PRK?

PRK /LASEK is a popular type of laser eye surgery for the correction of refractive errors such as myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. Better Vision explains all you need to know about this option.

PRK Surgery Benefits:

PRK procedure offers some advantages in comparison to other treatment options

Increased eligibility: This procedure can also be suitable for thinner corneas. PRK/LASEK only removes the very top outer layer of the eye leaving the maximum amount of remaining tissue for the laser to shape.

No flap complications: Possibilities of flap-related complications during and after surgery are eliminated with PRK/LASEK, and there is no risk of flap displacement

FAQ

What Is TransPRK?

Transepithelial Photorefractive Keratectomy, or TransPRK, is the surface treatment where the eye doesn’t require contact with any surgical instrument. Due to the smaller laser surface area, patients who have TransPRK benefit from a quicker recovery time and ultimately achieve outstanding results.

Benefits Of TransPRK:

No touch – all laser
It removes the epithelium more precisely and easily than in PRK
The corneal surface laser treated is smaller so it heals quicker
Overall treatment time is shorter than PRK
It minimizes the risk of corneal dehydration compared with PRK

Preparing For Surgery

Before the surgery, patients are usually directed by their doctor to:

Stop wearing hard contact lenses for at least four weeks and soft lenses for two weeks before surgery, because they may interfere with preoperative diagnostic tests.
Don’t use makeup, perfume, or lotion the day before and on the day of the procedure. These products may leave debris around the eye and eyelashes, which increases the chance of infection.
Arrange for alternative transportation directly after the surgery and possibly for the next few days following surgery.
