How does vision correction work?
Weak eyesight means light is not focused precisely on the retina. Laser reshapes the cornea — the eye's front window — with micron precision to correct that focus, while ICL implantation adds an internal lens that corrects the prescription without touching the cornea. The result in both cases is the same: clear vision without glasses.
The difference between techniques
Femto-LASIK: a laser flap then correction, recovery in a day or two. SMILE: no flap, a 2–3 mm incision, suited to athletes and dry eyes. PRK and Trans-PRK: directly on the corneal surface with no flap, best for thin corneas but recovery takes days longer. ICL: an internal lens for high prescriptions and thin corneas. The choice depends on corneal thickness and regularity, the prescription and lifestyle — not on what a friend told you.
Conditions for surgery
Age 18 or older, a prescription stable for at least a year, a healthy cornea of sufficient thickness without keratoconus, no pregnancy or breastfeeding, and no active inflammation or disqualifying disease. Results are most stable between 18 and 40, and up to 50 in selected cases; after 50, lens implantation is usually the better fit.
The day of surgery and after
Anaesthetic drops, minutes per eye, no pain. You may feel burning or watering for a few hours. Back to work within a day to a few days depending on the technique, and back to the gym usually after a week, avoiding swimming and eye rubbing for a period your doctor sets. Travel is possible after the first follow-up. In the long run you are completely normal, with routine check-ups like anyone else.
