In recent years, refractive surgery has made great strides, bringing innovations that improve the quality of life of those suffering from visual defects such as myopia, hyperopia and astigmatism. Among the most revolutionary techniques, the ReLEx SMILE (Small Incision Lenticule Extraction), an innovation that promises safer, less invasive vision correction with faster recovery times than traditional techniques.
Unlike LASIK and PRK, the ReLEx SMILE method uses only the femtosecond laser to create a corneal lenticule, which is then extracted through a small incision without the need to raise a corneal flap. This has a number of advantages, such as a reduced risk of post-operative complications and less impact on the biomechanical structure of the eye.
The aim of this article is to explore in detail this innovative technique, analyzing how it works, its benefits, indications and possible risks, providing all the information necessary for those who are considering undergoing this procedure.
What is ReLEx SMILE and how does it work?
ReLEx SMILE is a technique of latest generation refractive surgery, developed to correct visual defects by eliminating the dependence on glasses and contact lenses. Unlike previous techniques, which involve the creation of a corneal flap or the direct removal of superficial tissue, this procedure is based on a totally new approach and minimally invasive: for this reason only the most advanced eye clinics such as Vista Vision adopt the laser technique ReLEx SMILE.
The procedure takes place in three phases:
- Creating the lenticule – The femtosecond laser creates a small disk of tissue inside the cornea, called a lenticule, which corresponds to the amount of tissue needed to correct the vision defect.
- Minimal engraving – A microincision of approximately 2-4 mm is made through which the lenticule is extracted.
- Corneal reshaping – Once the lenticule is removed, the cornea assumes the correct shape to ensure clear vision.
This innovative technique allows to preserve the integrity of the corneal surface, reducing the risk of dry eye and post-operative complications.
