Le SMILE corrige-t-il l'hypermétropie ?

Historiquement, le SMILE traite surtout la myopie et l'astigmatisme myopique. La correction de l'hypermétropie par cette technique se développe et dépend de la plateforme utilisée ; le bilan tranche.

Le SMILE provoque-t-il moins de sécheresse ?

La mini-incision préserve mieux les nerfs cornéens, ce qui tend à réduire la sécheresse post-opératoire par rapport au LASIK chez de nombreux patients.

La récupération est-elle rapide ?

Oui, elle est généralement rapide, souvent intermédiaire entre le LASIK et la PKR selon les cas.

SMILE: correcting myopia through a mini-incision

SMILE is a recent technique that corrects myopia and astigmatism using a single femtosecond laser, through a very small incision, without a flap or excimer laser.

What does SMILE involve?

A femtosecond laser cuts a thin disc of tissue, called a lenticule, inside the cornea, shaped to match the desired correction. This lenticule is then removed through a mini-incision just a few millimetres wide. The cornea is reshaped without creating a flap and without an excimer laser.

Which refractive errors can be corrected?

SMILE is mainly aimed at myopia and myopic astigmatism. Indications are expanding as laser platforms evolve; the pre-operative assessment confirms eligibility.

What are the advantages?

The small incision better preserves the corneal surface and corneal nerves: post-operative dry eye is generally reduced. The absence of a flap is an advantage in terms of biomechanical stability. Visual recovery is rapid.

Recovery and follow-up

Vision improves quickly, with generally moderate discomfort during the first few days. As with any refractive surgery, eye-drop treatment and follow-up visits are planned. When SMILE is not indicated, LASIK or PRK remain excellent options.

Frequently asked questions

Does SMILE correct hyperopia?

Historically, SMILE mainly treats myopia and myopic astigmatism. Correcting hyperopia with this technique is developing and depends on the platform used; the assessment determines suitability.

Does SMILE cause less dryness?

The mini-incision better preserves the corneal nerves, which tends to reduce post-operative dryness compared with LASIK in many patients.

Is recovery fast?

Yes, recovery is generally fast, often intermediate between LASIK and PRK depending on the case.
