About PRK

What is PRK?

Photorefractive keratectomy (PRK) is a refractive laser surgery that reshapes the cornea in your eyes to correct myopia (short-sightedness), and hyperopia (farsightedness and astigmatism).

PRK aims to make you less dependent on glasses and contact lenses rather than completely correcting your vision.

When / Why do I need it

When should I get PRK?

  • If you are tired of using your glasses or contact lenses, you should consider PRK. It is an ideal procedure for people with thin, scarred, or irregular corneas.
  • It’s a completely bladeless, flapless procedure.
  • Takes only 5 to 15 minutes per eye.
  • Perfect for pilots, athletes, and others at risk of flap complications.

How do our experts perform PRK?

First, we use anaesthetic drops to numb your eyes for comfort. Then, the surgeon carefully removes the top layer of your cornea called the epithelium. Next, a precise laser reshapes your cornea to improve your vision. Finally, a soft contact lens is placed on your eye to aid healing. Your doctor will remove it in about 4 to 6 days.

However, you should not get PRK if:

  • You are pregnant.
  • You have advanced glaucoma.
  • You have a cataract or any cornea
  • You experience unstable refractive errors.


Anybody above the age of 18 having a stable refraction of +/- 0.5 D for 6 months.

  • Follow your doctor’s instructions for prescribed eye drops and oral medications.
  • Apply eye drops carefully, without touching the bottle tip to your eye.
  • Your doctor will remove the bandage contact lens after 4-6 days; don’t rub your eyes to prevent it from falling out. If it does, don’t try to replace it yourself; see your doctor.
  • Wear UV-protective goggles outdoors for the first 6 months.
  • Avoid face and hair washing for one week.
  • Don’t drive until your vision is clear.
  • Skip makeup for a month.
  • Hold off on swimming for 3 months.
