What We Treat

Phototherapeutic Keratectomy (PTK) in Dubai


Phototherapeutic Keratectomy (PTK) is a surgical treatment that treats various corneal conditions, such as corneal scars and recurrent epithelial erosion syndrome (which is characterized by a breakdown of the corneal surface).

During this surgery, excimer laser is used to change the shape of the cornea (the eye’s clear, protective outer layer); this improves the way the retina (the thin layer of tissue that lines the back of the eye) focuses on light rays the eye is exposed to.

Phototherapeutic keratectomy offers several advantages, including:

  • Minimally-invasive procedure.
  • Quick visual recovery.
  • Ability to repeat the treatment.
  • A smoother corneal surface.


Am I a suitable candidate for PTK surgery?

To determine if this laser surgery is suited to you, the below factors must be established:

  • Test for other eye problems. It’s essential to check for any eye problems that could affect the surgery, or PRK could potentially worsen them.
  • Examine your vision to ensure it has remained the same and highlight how high the refractive error is and whether PRK is a suitable option to correct your vision.
  • Map and measure the cornea surface. The ophthalmologist will check the thickness of the cornea and make precise measurements of the cornea’s surface to configure the computer-based laser during the surgery.


What does PRK surgery involve?

This surgery doesn’t require general anesthesia and typically takes 5-10 minutes per eye to complete. The patient may require local anesthesia in the form of eye drops to ease any discomfort.

The procedure involves:

  • An eyelid holder will be placed on each eye to prevent blinking.
  • The surgeon will remove the corneal surface cells. This process may be performed using a laser, alcohol solution, or a brush.
  • The excimer laser, which is preset to match your cornea dimensions, will reshape each cornea.
  • A clear, non-prescriptive contact lens is placed on each eye as a protective measure, avoiding the risk of infection and keeping the eyes clean.


Its recommended to keep the bandage on between 3-7 days.

What happens after PTK surgery?

Your eyes may be watery or reddish following the surgery, but these side effects will subside in a few days. During the first week, your vision will be slightly blurry, but it will improve after a month, with full improvement after three to six months.

You should rest at home for a couple of days and take the prescribed medication to ease any discomfort. You should also avoid touching or rubbing your eye during your recovery. Most patients have long-term results after a PTK and do not require a second treatment.
