Abstract

ReLEx® (Refractive lenticule extraction) SMILE® (SMall Incision Lenticula Extraction) is the third generation of laser eye surgery, which is a follow-on to PRK (the first generation) and LASIK (the second generation).
This technology has expanded the possibilities for the comfort and safety of the procedure, reduced the requirements for the thickness of the cornea, and made it extremely comfortable for the patient.
SMILE® method helps improve vision in case of myopia, myopic and mixed astigmatism. The article analyzes the advantages and disadvantages of this technology, its possible risks and side effects.
The data represented in this article was obtained by analyzing scientific publications and practical expertise.
