Overview of Vision Correction Procedures
What Is LASIK?
LASIK (Laser-Assisted In Situ Keratomileusis) reshapes the cornea using a laser flap. It’s fast,
with most patients achieving 20/20 vision within a day. Success rates are high—up to 99%
reach at least 20/40 vision, and over 90% achieve 20/20 or better (Kraff Eye Institute, Cleveland
Clinic).
What Is PRK?
PRK (Photorefractive Keratectomy) uses a laser to reshape the cornea by removing its outer
layer. There’s no flap, making it suitable for people with thinner corneas. Vision takes longer to
clear—up to a month—but final outcomes match LASIK (Barnet Dulaney Perkins Vision
Correction).
What Is Visian ICL?
Visian ICL involves implanting a biocompatible Collamer® lens between the iris and natural
lens. It’s reversible, doesn’t thin the cornea, and treats high myopia or astigmatism. A recent
FDA-approved EVO model includes a central port to maintain intraocular fluid flow (Cleveland
Clinic).
Procedure Comparison
| Feature | LASIK | PRK | Visian ICL |
| Flap/Incision | Corneal flap | Epithelium removed | Small corneal incision (no flap) |
| Corneal Tissue | Ablation of central cornea | Ablation of corneal surface | No removal, preserves natural cornea |
| Recovery Time | 1-2 days for vision; full in 1-2 weeks | Up to 1 month for clarity; bandage contact used (Wikipedia, Cleveland Clinic) | Vision often clear within 1-3 days; stable in a week |
| Ideal Candidates | Mild-to-moderate errors; adequate cornea | Thin/irregular corneas; active lifestyles | High myopia/astigmatism or thinner corneas |
| Dry Eye Risk | Moderate (seen in ~20%) | Similar to LASIK; epithelium healing may cause discomfort | Lower risk; cornea is intact |
| Reversibility | Not reversible | Not reversible | Removable; lens can be exchanged or removed |
| Ideal for High Rx | Up to ~ -10 D myopia | Similar to LASIK; less common for high errors | Excellent for high myopia (> -10 D), thin corneas |
Who Is a Good Candidate?
LASIK
- Age 18+ with stable prescription (within ~1 D for 1 year)
- Myopia, hyperopia, or astigmatism within treatable ranges
- Minimum corneal thickness to support flap creation
- No active eye conditions or severe dry eye (Wikipedia, Wikipedia, eyewiki.org, au.discovericl.com)
PRK
- Similar criteria to LASIK, but suited for thin corneas or patients in high-impact professions (Alliance Vision Institue)
Visian ICL
- Ages 21–45, stable prescription, no glaucoma, sufficient anterior chamber depth (≤ 3 mm) (clevelandeyeclinic.com)
- Ideal for high myopia or astigmatism, with concerns about corneal thinning or dry eyes
Recovery and Outcomes
LASIK
- Quick—70–80% have functional vision within 24 hours (Wikipedia)
- Minor discomfort, minimal downtime
- Risks include dry eye (up to 20%), haze, visual aberrations (Wikipedia, au.discovericl.com)
PRK
- Slower; bandage lenses for 3–5 days, final clarity maybe 4 weeks
- Suitable for physically active individuals where flap could be dislodged
Visian ICL
- Vision often restored within 1–3 days; minimal discomfort
- Excellent acuity; FDA data shows 90.5% within ±0.5 D of target (PMC)
- Risks include cataract development, endothelial loss—but rare with EVO model’s fluid port (PMC)
Pros & Cons Summary
