# LASIK vs SMILE

LASIK and SMILE are modern laser eye surgeries that correct short-sight and astigmatism. They differ mainly in how tissue is removed and how the cornea is accessed.

## How each procedure works

LASIK uses a flap and excimer laser ablation on the corneal surface. SMILE creates a small internal disc of tissue with a femtosecond laser, then removes it through a tiny incision.

- LASIK involves lifting a larger flap that is then repositioned
- SMILE uses a keyhole incision without a broad flap
- Both can deliver excellent visual outcomes in suitable candidates
- SMILE currently treats a narrower range of prescriptions than LASIK in some clinics

## Comfort, recovery, and suitability

Recovery is usually quick with both techniques. Subtle differences may matter for specific lifestyles.

- SMILE may cause less dry eye in some patients because fewer nerves are cut
- LASIK offers very predictable results for a wide prescription range
- Contact or impact sports players may prefer a flap-free approach like SMILE
- Assessment includes corneal maps, thickness, and personal goals
