LASIK for Astigmatism: What Medellín Clinics Can Do
Astigmatism — an irregularly shaped cornea that causes blurred vision at all distances — is one of the most common refractive errors and one of the most successfully treated by LASIK. If you've been told you have astigmatism and wondered whether LASIK can fix it, the answer is almost certainly yes, and Medellín clinics are well-equipped to do it.
| Astigmatism Level | Diopters | LASIK Suitable? | Expected Outcome |
|---|---|---|---|
| Mild | 0.5-1.0 D | Excellent candidate | 95%+ achieve 20/20 |
| Moderate | 1.0-3.0 D | Good candidate | 90%+ achieve 20/20 |
| High | 3.0-6.0 D | Usually suitable with advanced tech | 85%+ achieve 20/25 or better |
| Very high | >6.0 D | Case-by-case; ICL may be preferred | Discuss alternatives with surgeon |
Why Technology Matters More for Astigmatism
Correcting astigmatism requires the laser to reshape the cornea asymmetrically — removing more tissue in one axis than the other. This is more complex than simple myopia correction (which is symmetrical), and the precision of the laser platform directly impacts the result. Wavefront-guided treatment maps your eye's specific optical irregularities and creates a custom correction profile. Topography-guided treatment uses corneal mapping to address irregularities in corneal shape directly.
Medellín clinics offering these technologies use the same platforms as top US practices — Wavelight EX500, Zeiss MEL 90, and Alcon iDesign. The technology is identical; the price is 70% less. For patients with significant astigmatism, the advanced diagnostic and treatment capabilities available in Medellín make it possible to achieve results that weren't possible with earlier-generation lasers.
