No single procedure suits everyone. Here's a clear, honest comparison of every EYEONCE vision solution — how each works, the equipment behind it, recovery, suitability and the right age for each — so you can decide with confidence.
The essentials at a glance. Your precision exam always confirms the safest, best-fit option for your eyes.
| Procedure | How it works | Corneal flap | Best for | Recovery | Reversible |
|---|---|---|---|---|---|
| SMILE PRO | Flapless, bladeless keyhole laser (femtosecond) — our most advanced generation | None · 2–4 mm keyhole | Myopia & astigmatism; active lifestyles; dry-eye concern | Next-day functional vision | No (tissue reshaped) |
| SMILE LASIK | Flapless keyhole laser — the proven SMILE technique | None · 2–4 mm keyhole | Myopia & astigmatism; sport & travel; lower dry-eye risk | Next-day functional vision | No (tissue reshaped) |
| LASIK | All-laser flap created, then cornea reshaped | Flap (all-laser) | Suitable corneas wanting fastest recovery | 1–2 days | No (tissue reshaped) |
| LASEK | Surface treatment — epithelium preserved, no flap | None · surface | Thinner corneas; high-impact / contact sports | Gradual, over 1–few weeks | No (tissue reshaped) |
| ICL | A soft biocompatible lens implanted inside the eye — no cornea removed | None (no cornea removed) | High myopia; thin corneas; dry eyes | Clearer within a day; settles over 1–2 weeks | Yes — removable |

Technology assists — but your operating surgeon makes every clinical decision, from evaluation through recovery.
Your eyes change over time — and the best solution changes with them. A general guide (your exam confirms the details):
SMILE PRO, SMILE LASIK, LASIK/LASEK and ICL suit adults 18+ with a stable prescription for at least a year. Ideal through the 20s, 30s and early 40s — before presbyopia sets in.
Age-related loss of near focus typically begins around 40–45. Premium full-range and multifocal lenses restore near, intermediate and far vision.
Cataracts usually develop from the 50s–60s onward. We recommend a cataract screening from your 50s — earlier if you notice glare, halos or clouding. A premium IOL can correct cataract and presbyopia together.
Between 45 and 55, several options may apply — this is exactly where a personalized exam and honest guidance matter most. Message us and we'll help you decide.
