Alternatives

PRK

No flap created. Better for thinner corneas, contact athletes, and military careers. Slower recovery (1–2 weeks of blurry vision).

SMILE / ReLex SMILE

Femtosecond laser creates a small lenticule extracted through a tiny incision. Less dry eye than LASIK; some surgeons consider it the new standard for myopia.

ICL (Implantable Collamer Lens)

Lens implanted behind the iris. Reversible; ideal for high myopia or thin corneas where LASIK isn't safe.

Glasses or contacts

Free of surgical risk. For patients with risk factors (thin cornea, dry eye), this is often the right answer.
