PRK (Photorefractive Keratectomy)
PRK is the first generation of laser vision correction. It's a surface ablation procedure that reshapes the cornea to correct refractive errors such as myopia, hyperopia, and astigmatism. PRK is particularly suitable for patients with thin corneas or those who may not be candidates for LASIK.
Step-by-step Explanation:
- Epithelium Removal: A diluted alcohol solution is applied to dissolve the epithelial layer of the cornea.
- Layer Removal: The epithelial layer is gently removed or moved aside using a manual instrument.
- Corneal Sculpting: An excimer laser precisely reshapes the exposed corneal tissue to correct the refractive error.
- Protection: A bandage contact lens is placed over the eye to protect it while the epithelium regrows.
Eligibility Criteria:
- Age: 18 years or older with stable vision
- Corneal thickness: Suitable for those with thinner corneas
- Refractive error: Can treat a wide range of prescriptions
- Active lifestyle: Good for those at risk of eye trauma (e.g., contact sports)
Benefits:
- No flap-related complications
- Suitable for patients with thin corneas
- May be safer for patients at risk of eye injuries
- Potentially better for treating certain higher-order aberrations
Potential Risks:
- Longer initial recovery time compared to LASIK
- Potential for corneal haze (usually temporary)
- Discomfort in the first few days post-surgery
- Temporary dry eye symptoms
Recovery Process:
- First few days: Expect discomfort and blurred vision
- 3-5 days: Bandage contact lens removed
- 1-4 weeks: Vision starts to stabilize
- 3-6 months: Full visual recovery typically achieved
