Procedure comparison

A femtosecond laser carves a thin lenticule inside the cornea, and the surgeon lifts it out through a small incision. There is no flap to fold back, so the surface stays quiet and most people are back to screens within a few days. It suits everyday short-sight and mild astigmatism, and it is often the first suggestion when someone is nervous about a flap. Very high prescriptions and irregular corneas usually push the choice elsewhere.

SMILE Pro is the newer generation of the same flap-free approach, with the laser step compressed to a few seconds and built-in alignment aids that track the eye during treatment. The practical difference for a patient is less time under the laser and less suction pressure on the eye, which matters if you find the fixation light hard to hold. Suitability and recovery pattern stay close to standard SMILE, so the choice often comes down to which platform your clinic runs and what your measurements support.

The femtosecond laser creates a thin flap, the surgeon folds it back, and an excimer laser reshapes the tissue beneath. Vision often clears within a day, which is why it remains the familiar standard for a wide range of prescriptions, including higher short-sight and astigmatism combinations. The trade-off is a corneal flap and the dryness that tends to accompany it in the first months. Eyes that already run dry, or corneas that are thin for the amount of correction asked, are usually steered toward a flap-free route.

TransPRK skips both flap and alcohol, with the excimer laser removing the surface layer and reshaping the cornea in one pass. Nothing is cut, so there is no flap complication risk and the approach is often chosen when the cornea is thin or the surface is already fragile. Recovery is the honest cost: the first days are uncomfortable and functional vision can take a week or more to settle. For contact-sport players, people in dusty outdoor work, and thin corneas, that trade is frequently worth it.

A phakic IOL is a small lens placed inside the eye in front of your natural lens, correcting high short-sight or astigmatism that laser reshaping cannot safely cover. Corneal tissue is never removed, which is why it is discussed when the prescription is too high or the cornea too thin for laser. It is an intraocular procedure with its own monitoring requirements, and the trade-off is a longer clinical relationship rather than a longer healing week. Endothelial cell counts and anterior chamber depth become part of the regular check-ups.
