LASIK provides long-lasting vision correction that is permanent in the sense that the laser reshaping of the cornea does not reverse. However, age-related changes (presbyopia, cataract) and regression can affect vision over time.
Key Facts
- The corneal reshaping done by LASIK laser is physically permanent
- Regression (mild prescription return) can occur in 5–10% of high prescriptions over years
- Presbyopia (age-related near vision loss from age 40) affects everyone including post-LASIK patients
- Cataracts in older age may affect vision independently of LASIK
- Enhancement (re-treatment) is available if regression is clinically significant
Guidelines & Tips
- LASIK is considered a permanent procedure — not reversible
- Most patients enjoy 10–20+ years of glasses-free life after LASIK
- High prescriptions have a slightly higher chance of gradual regression over time
- Annual eye checks allow early detection of any regression or age-related changes
- Regression is treatable with enhancement LASIK in most patients
- Modern Contoura and SMILE technologies have lower regression rates than older LASIK
