Refractive lenticule extraction (ReLEx/SMILE) uses a femtosecond laser to create and remove a corneal lenticule, correcting myopia and astigmatism without a flap or excimer laser. This advanced technique offers a precise and minimally invasive approach to vision correction.

Area of Science:

  • Ophthalmology
  • Laser Surgery

Background:

  • Refractive errors like myopia and astigmatism significantly impact visual acuity.
  • Traditional refractive surgeries often involve creating corneal flaps and using excimer lasers.

Purpose of the Study:

  • To detail the stages of Refractive Lenticule Extraction (ReLEx/SMILE) using a femtosecond laser.
  • To explain the avoidance of corneal flaps and excimer lasers in this method.
  • To present potential errors and their mitigation strategies.

Main Methods:

  • Exclusive use of a femtosecond laser to generate a refractive lenticule within the cornea.
  • Extraction of the lenticule through a small corneal incision.
  • Elimination of the need for corneal flap creation and excimer laser ablation.

Main Results:

  • ReLEx/SMILE enables refractive correction through lenticule extraction.
  • The technique avoids flap-related complications and excimer laser side effects.
  • The method was assessed and classified by the Joint Commission for Refractive Surgery in 2013.

Conclusions:

  • ReLEx/SMILE is an advanced refractive surgical technique for myopia and myopic astigmatism.
  • The method offers a flapless and bladeless alternative to traditional laser eye surgery.
  • Understanding the technique's stages and potential pitfalls is crucial for successful outcomes.
