PRK (Photorefractive Keratectomy)
PRK, the progenitor of laser vision correction, remains a viable option for specific patient populations, particularly those with reduced corneal pachymetry or individuals at risk of traumatic flap dislocation.
Key Clinical Features
- Epithelial ablation surgery
- Indicated for patients with corneal thickness <500 μm
- Economical refractive surgery option
- Absence of lamellar flap, mitigating flap-related complications
Procedural Protocol
- Topical anesthesia administration
- Mechanical or alcohol-assisted epithelial debridement
- Excimer laser stromal ablation for corneal reshaping
- Application of mitomycin C (optional, for high corrections)
- Placement of bandage contact lens
Post-operative Management
- Healing period: 3-5 days for re-epithelialization, 1-3 months for visual stabilization
- Gradual improvement in visual acuity over several weeks
- Potential for initial post-operative pain and photophobia
- Regular follow-up examinations to assess corneal healing and refractive outcomes
Ideal Candidates
- Patients with corneal thickness <500 μm
- Individuals with mild to moderate refractive errors (-1.00 to -6.00 D)
- Patients at risk of traumatic corneal injury
