Photorefractive Keratectomy (PRK) Cornea Eye Surgery

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.

Photorefractive Keratectomy (PRK)

What Is PRK?

Surgery on the eye Surface

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

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 smaller laser surface area, patients who have TransPRK benefit from a quicker recovery time and ultimately achieve outstanding results.

What Is TransPRK?

TransPRK is a new one-step, incision-free procedure. Using the laser, the epithelium (the regenerative outer surface of the eye) is gently removed and the cornea precisely reshaped. The procedure enables the contour of the cornea to be reshaped in less than one minute. Unlike LASIK, there is no incision or flap created in the cornea with TransPRK.

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 shortened than PRK
It minimizes the risks of corneal dehydration than 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 make-up, 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.
