PRK is a surface laser procedure used to correct suitable refractive errors. It changes corneal shape without creating a LASIK flap. The choice between techniques depends on your examination.

Key points
- Confirm corneal shape, thickness and prescription stability.
- Surface healing and visual recovery differ from LASIK.
- Use only the prescribed drops and protection plan.
- Attend the review appointments and report worsening symptoms.

PRK and LASIK: the main difference
PRK treats the cornea after the surface layer has been removed; that layer heals afterwards. LASIK works beneath a flap. Neither approach is automatically the best choice for every eye.
Assessment and alternatives
The clinician checks the prescription, corneal measurements, tear film, other eye disease and health factors. Discuss glasses, contact lenses and other procedures where appropriate. General suitability questions for refractive surgery are outlined by the FDA.[1]
Recovery and risks
Surface discomfort, light sensitivity and fluctuating vision may occur during recovery. Infection, haze, persistent dry eye, glare or an incomplete correction are among the issues to discuss. Ask for the clinic’s expected recovery pattern and the symptoms that require prompt assessment.
Your follow-up plan
A protective contact lens may be used while the surface heals. The clinic decides when it is removed, how drops are used and when activities can resume. Do not remove the lens or change medicines yourself.
Planning a visit
Confirm the examination, procedure, review visits, accommodation and return-travel advice. The written quote should distinguish one-eye and two-eye treatment and identify included tests, drops and follow-up.
Planning your visit to Shiraz
Ask about the appropriate specialty, appointment details and practical services you need. Your treating clinician confirms the diagnosis, suitability, treatment and follow-up after assessment.
