PRK (Photorefractive Keratectomy) was the world’s first laser vision correction procedure and remains an excellent option for patients who are not suitable for LASIK. Here is everything you need to know about PRK surgery.
How PRK Works
Unlike LASIK, PRK does not create a corneal flap. Instead, the thin outer layer of the cornea (epithelium) is gently removed, and the excimer laser reshapes the underlying corneal stroma directly. The epithelium then regenerates naturally over 3–5 days after surgery.
Who Is PRK Best For?
- Patients with thinner corneas who cannot safely have a LASIK flap
- Patients with irregular corneal surfaces
- High-impact contact sports players
- Military and police personnel
PRK Recovery Timeline
- Days 1–3: Bandage contact lens in place; mild-moderate discomfort
- Days 4–5: Bandage lens removed; vision begins improving
- 1–2 weeks: Vision functional; return to office work
- 1 month: Driving clearance for most patients
- 3–6 months: Full vision stabilisation
PRK Success Rate
PRK’s long-term results are equivalent to LASIK — approximately 95–98% of patients achieve 6/6 vision. The outcome is the same; only the recovery timeline differs. At Centre For Lasik, we offer Trans-PRK (no-touch PRK), the most advanced surface ablation technique available.
