Effects of Keratorefractive Surgery on Corneal Biomechanics: A Review of the Literature

This review article focuses on studying changes in corneal biomechanical properties following refractive surgeries. Objective : to analyze the literature on the effects of major laser vision correction techniques on the biomechanical properties of the cornea. Materials and Methods . For this review, we conducted a literature search in the databases PubMed , Scopus , and e-Library from 1992 to 2023 using the following keywords: “ ametropia ”, “ corneal biomechanical properties ”, “ keratorefractive surgery ”, “ LASIK ”, “ FEMTOLASIK ”, “ SMILE ”, “ CLEAR ”. Results . Studies indicate that the development of new myopia correction techniques with minimal damage to the superficial corneal layers represents a promising direction in ophthalmology. These methods provide better protection for corneal structural integrity, which is crucial for preventing postoperative complications. Conclusion . The choice of refractive method for myopia correction should account for changes in corneal biomechanical properties and demonstrate the best safety profile concerning the preservation of corneal mechanical stability.
