Photorefractive Keratectomy (PRK) at Eye Clinic DRHC Dubai

Overview

Photorefractive Keratectomy (PRK) is a type of laser eye surgery designed to correct vision problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. PRK reshapes the cornea, the clear front surface of the eye, to improve how light is focused on the retina. This procedure is an excellent option for individuals who may not be ideal candidates for LASIK due to thin corneas or other eye conditions.

How PRK Works

PRK involves the removal of the very thin outer layer of the cornea, called the epithelium, which allows the laser to reshape the underlying corneal tissue. The excimer laser, which is highly precise, is then used to sculpt the cornea, altering its curvature to correct the refractive error. Unlike LASIK, where a flap is created in the cornea, PRK involves no flap, making it a suitable option for patients with certain corneal conditions.

Who is a Candidate for PRK?

PRK is suitable for individuals who:

• Have myopia, hyperopia, or astigmatism
• Have thin corneas, which may disqualify them from LASIK
• Engage in contact sports or activities with a higher risk of eye injury, where a corneal flap (as in LASIK) might be problematic
• Prefer a flapless procedure
• Are over 18 years old and have stable vision prescriptions for at least one year

Procedures Details

The PRK procedure at DRHC Dubai is performed on an outpatient basis and typically takes about 15-30 minutes for both eyes:

1. Preparation: The eyes are numbed with anesthetic eye drops to ensure comfort throughout the procedure.
2. Epithelium Removal: The outer layer of the cornea (epithelium) is gently removed using a specialized tool or alcohol solution.
3. Laser Reshaping: The excimer laser is used to reshape the corneal tissue, correcting the refractive error. The laser is guided by a computer to ensure precise adjustments based on your specific eye measurements.
4. Healing Process: After the laser treatment, a soft contact lens is placed over the cornea to protect it while the epithelium regenerates, which typically takes about 3-5 days.

Recovery and Results

Recovery from PRK is slightly longer than LASIK, as the epithelium needs time to heal. During the first few days after the procedure, you may experience:

• Mild discomfort or sensitivity to light
• Blurred vision
• Dry eyes

These symptoms are temporary and can be managed with prescribed medications and eye drops. Vision improvement occurs gradually, with most patients achieving significant vision clarity within a few weeks, and full results typically manifesting within three months.

Benefits of PRK

• No Corneal Flap: PRK is ideal for patients with thin corneas or those who prefer a flapless procedure, reducing the risk of flap-related complications.
• Long-Term Stability: PRK offers excellent long-term vision correction, with results that are comparable to LASIK.
• Reduced Risk of Dry Eye: Some patients may experience less dry eye symptoms with PRK compared to LASIK.
