"Permanent" is accurate but frequently misunderstood in how it's marketed — here's what LASIK's permanence actually means clinically, and what it doesn't cover.
What "permanent" actually refers to
The corneal reshaping itself is permanent — your cornea doesn't gradually revert to its pre-surgery shape. In that specific, technical sense, LASIK's correction of your prior nearsightedness, farsightedness, or astigmatism is a one-time, lasting change.
LASIK permanently corrects the refractive error present at the time of surgery. It doesn't prevent unrelated, natural age-related vision changes that develop afterward — this distinction is the source of most "does LASIK really last" confusion.
What can still change your vision after LASIK
- Presbyopia — the natural age-related decline in near-focusing ability, unrelated to your original prescription (see our dedicated guide)
- Cataracts — an age-related lens condition, unrelated to corneal correction, that most people eventually develop regardless of LASIK history
- Rarely, some regression — a small percentage of patients experience a partial return of their original prescription over time, addressed through enhancement procedures if needed (see our enhancement rates guide)
The honest framing
LASIK is genuinely one of the most durable outcomes in elective surgery — the vast majority of patients maintain their corrected vision for life without needing any further refractive procedure. It's worth understanding precisely what it does and doesn't guarantee, rather than either oversimplified extreme.
What to expect long-term
Most patients never need an enhancement. Presbyopia will eventually affect near vision regardless of LASIK history, simply as a normal part of aging — this isn't a LASIK failure, just biology continuing on its own timeline.
