Parameters to have PRK are similar to those for LASIK surgery. Patients with marginally thin corneas may be more suited to PRK surgery. Patients with dry eyes may also be better suited to have PRK surgery.
PRK works by removing the surface cell layers of the eye before applying a MEL90 excimer laser to reshape the cornea. A contact lens is then placed on the corneal surface to allow the corneal epithelium to regrow over the ensuing days.
The benefits of PRK include:
- Quick surgery
- No flap creation
- Good for thinner cornea and dry eye conditions
Any surgical or invasive procedure carries risks. Before proceeding, we will discuss these risks with you to ensure you are well informed and confident with your decision.
If you are unsuitable for PRK, we can perform trans-epithelial PRK. This is an excellent, accurate way to treat refractive error without the need to remove the epithelium manually.
Step 1: We remove the eyes epithelial layers
Step 2: We apply the laser
Step 3: We apply a drug called Mitomycin-c to reduce the likelihood of developing corneal haze
Step 4: We apply a contact lens that acts as a bandage
Most people see 20/20 or better after PRK, as clearly as they would after LASIK.
