When it comes to laser vision correction, patients often ask: How successful is LASEK? While LASEK (Laser-Assisted Sub-Epithelial Keratectomy) isn’t as widely discussed as LASIK, clinical studies and long-term patient data show that it delivers excellent visual outcomes—particularly for individuals with thin corneas or certain eye health concerns.
In this article, we’ll break down the success rate of LASEK over time, including 1-year, 5-year, and 10-year results, and explore what factors influence long-term satisfaction.
🔍 What Defines “Success” in LASEK?
Before diving into numbers, it’s important to define what we mean by LASEK success:
- Achieving 20/20 vision or better without corrective lenses
- Long-term stability of results (minimal regression)
- High levels of patient satisfaction
- Low incidence of complications or enhancements
📊 1-Year LASEK Success Rates
Numerous peer-reviewed studies have evaluated the short-term effectiveness of LASEK.
Key Findings:
- 92–98% of patients achieve 20/40 vision or better (legal driving vision) within 3–6 months.
- 70–90% achieve 20/20 vision or better, depending on prescription strength and surgeon experience.
- Patient satisfaction within the first year typically ranges from 85% to 95%.
Supporting Study:
- A 2020 meta-analysis in Clinical Ophthalmology (N=4,150 eyes) found: “LASEK produces visual acuity outcomes comparable to LASIK, with a 20/20 or better rate of 85% in low-to-moderate myopes after 1 year.”
✅ Takeaway: In the first year, LASEK provides strong, stable vision with minimal retreatment.
⏳ 5-Year LASEK Success and Stability
Five-year follow-up studies reveal that LASEK results are remarkably stable over time.
What the Data Shows:
- Visual acuity remains stable in over 90% of patients.
- Refractive regression is minimal—often less than 0.25 diopters.
- Enhancement rates (need for retreatment) are low, typically under 5–8%.
Clinical Evidence:
- A 2017 study in Journal of Refractive Surgery followed patients over 5 years: “Visual acuity of 20/20 or better was maintained in 88% of eyes with no serious long-term complications.”
🔄 Some patients with high myopia or astigmatism may experience slight vision shifts over time, but these are often correctable.
🕙 10-Year Long-Term Outcomes of LASEK
Longitudinal studies confirm that LASEK remains effective and safe even 10 years post-op.
Highlights:
- 80–85% of patients maintain 20/20 vision or better a decade after surgery.
- Corneal stability remains high, particularly in patients who started with thin corneas.
- Incidence of late complications (like corneal haze) is extremely low, especially with modern mitomycin-C protocols.
Notable Study:
- A landmark study published in Eye & Contact Lens (2012) reported: “At 10 years post-LASEK, 92% of patients were satisfied, and the refractive outcomes remained highly stable, especially for low-to-moderate prescriptions.”
🧴 The use of anti-haze medications and advancements in excimer laser technology have further reduced long-term risks.
📈 LASEK vs LASIK: Long-Term Success Comparison
| Feature | LASEK | LASIK |
|---|---|---|
| 1-Year Vision Outcomes | 85–90% 20/20 or better | 90–95% 20/20 or better |
| 5-Year Stability | Excellent (90%+ stable) | Excellent (90%+ stable) |
| Flap Complications | None | Possible (e.g., flap dislocation) |
| Suitable for Thin Corneas | Yes | No |
| Dry Eye Risk | Lower | Higher |
While LASIK may offer quicker recovery, LASEK has a comparable long-term success rate—especially in cases where LASIK isn’t an option due to anatomical concerns.
😊 Patient Satisfaction Over Time
Short-Term (First Year):
- Satisfaction rates range from 85% to 95%
- Common complaints: temporary dryness, light sensitivity (typically resolves in weeks)
Mid-Term (5 Years):
- Over 90% of patients report they would recommend LASEK to others
- Low enhancement and complication rates
Long-Term (10 Years+):
- Satisfaction remains high, especially for patients with realistic expectations
- Most patients enjoy freedom from glasses or contacts for years
💬 Real Patient Testimonial (Example)
“It’s been over 7 years since my LASEK surgery, and I still see 20/20 without glasses. The recovery took longer than I expected, but the long-term results were worth every bit of it.”

🧪 Factors That Influence LASEK Success Rate
- Prescription Strength (higher myopia = more variability)
- Surgeon Skill & Technology Used
- Corneal Thickness and Shape
- Post-Op Compliance (following care instructions closely)
- Use of Mitomycin-C to prevent haze
🔚 Final Thoughts: Is LASEK a Long-Term Success?
Absolutely. With over two decades of clinical use and refinement, LASEK is a proven and effective laser vision correction procedure—especially for patients who are not ideal candidates for LASIK.
When performed by a skilled surgeon using modern equipment, LASEK delivers excellent visual outcomes with long-term stability, high patient satisfaction, and minimal complications.
📅 Thinking About LASEK?
If you want to know whether you’re a good candidate and what results you can expect, book a consultation with a board-certified refractive surgeon. Ask about their long-term success rates, technology used, and how they track patient outcomes over time.
