As with any surgical procedure, there are risks associated with PRK. Potential candidates for surgery should discuss these risks with their provider before they make the decision to have the procedure.

Many patients experience some discomfort in the first 24 to 48 hours after PRK surgery, and almost all experience sensitivity to light. Blurred vision and tearing may also occur as the cornea heals in the first week after the procedure.

Other short-term side effects may include:

  • Dry eyes
  • Infection
  • Glare
  • Seeing halos around images. These are most noticeable at night, for instance, while driving.

Long-term side effects may include:

  • Very rarely, loss of best vision achieved with glasses
  • Seeing a minor glare, or rarely, worse than a minor glare, which can be permanent, depending on a patient’s pupil size in dim light
  • Mild halos around images, or rarely, worse than mild halos
  • Dry eyes
