Advanced Vision Correction for Challenging Cases
Whether you choose traditional PRK or our advanced ASA option, you get the safety and corneal preservation of surface ablation. We'll help you decide which is right for your eyes.

What are PRK and Advanced Surface Ablation (ASA)?
Both PRK and ASA are laser vision correction procedures that reshape the cornea without creating a flap—making them ideal for thin corneas, athletes, and active patients. The key difference lies in the technique and outcomes.
Traditional PRK
(Photorefractive Keratectomy)
PRK removes the outer cornea layer (epithelium) to expose the tissue beneath, which an excimer laser reshapes to correct vision errors. The epithelium naturally regenerates over 3–5 days.
Proven advantages:
- No flap—full corneal integrity preserved
- Suitable for thin corneas
- Excellent long-term stability
- Lower cost than ASA
- Can correct myopia and astigmatism
- No risk of flap-related complications
Advanced Surface Ablation
(ASA)
ASA is an enhanced version of PRK that incorporates three refinements to improve healing and visual outcomes:
Alcohol-assisted epithelial removal: Faster, more controlled removal than mechanical scraping
Mitomycin C (MMC) application: Reduces haze formation and enhances night vision
Advanced customized laser algorithms: Tailored treatment profiles for superior vision correction precision
Key benefits over traditional PRK:
- Faster visual recovery (2–3 months vs. 3–4 months)
- Superior night vision and reduced haze risk
- Smoother visual progression
- Slightly better outcomes in complex cases
- Recommended for patients prioritizing faster healing

Recovery & Results
Visual recovery
Slower than LASIK; vision stabilizes over 1-3 months. Full clarity typically achieved by month 3.
Timeline
Day 1-3
Contact lens in place for comfort and protection
Week 1-2
Vision gradually improves; epithelium regenerates
Week 3-4
Most comfortable for light activities
Month 1-3
Vision continues to improve and refraction stabilizes
Month 6
Final refraction plateau
PRK vs. LASIK
PRK has no flap, making it safer for athletes and those with thin corneas. Recovery is slower, but outcomes are equally excellent long-term. LASIK offers faster recovery but requires adequate corneal thickness.
FAQ
How do I know if I should choose PRK or ASA?
During your consultation, we'll evaluate your corneal thickness, prescription, healing history, and lifestyle. ASA is ideal if faster recovery is important; PRK is excellent if you prioritize cost and are comfortable with standard healing timelines.
Why is recovery slower with PRK/ASA than LASIK?
The epithelium takes 3–5 days to regenerate. During this time, the eye is more sensitive and may have fluctuating vision. With LASIK, the flap acts as a protective bandage, allowing faster visual stability.
Will I have pain during recovery?
Some discomfort is normal for 3-5 days. Prescribed pain relief and protective contact lenses minimize this.
Is either procedure as effective as LASIK?
Yes. Long-term vision correction outcomes are equivalent across all three procedures. PRK and ASA may offer superior results for thin corneas and better night vision profiles.
Can I choose between PRK and ASA, or will it be recommended?
If your corneas are too thin for LASIK, we'll recommend PRK or ASA based on your anatomy and goals. Otherwise, the choice is yours—we'll present both options and help you decide.
When can I return to sports?
Most light activity within 2-3 weeks; high-impact sports after 6-8 weeks.
