PRK stands for Photorefractive Keratectomy. Often used synonymously with Epi-LASIK, it is a form of advanced surface ablation which reshapes the cornea and corrects any refractive error without creation of a flap.
What is PRK?
How does PRK work?
During PRK surgery, the layer of epithelium is gently removed and a corrective laser is then applied to reshape the cornea to correct any refractive error. The epithelium is then allowed to heal, restoring visual clarity.
What are the benefits of PRK (Epi-LASIK)?
Benefits of PRK include:
- Freedom from glasses and contact lenses
- No risk of flap related complications e.g. Flap dislocation, flap striae, epithelial ingrowth
- Tissue saving as none of the corneal tissue is used for flap creation
- May be more suitable in patients with thin corneas
- May have less dry eyes compared with LASIK
Who is a good candidate for PRK?
A thorough assessment should be done before proceeding with any laser vision correction. In general, a suitable candidate for PRK surgery includes patients who:
- More than 18 years old
- Healthy corneas
- Stable vision and refractive errors
- Keen to be free of glasses or contact lenses
- Keen to avoid LASIK flap related complications
- Understands the initial discomfort and longer recovery period
