Summary
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.
