THE EFFECT OF EXIMERLASER INTERVENTIONS ON THE BIOMECHANICAL PROPERTIES OF CORNEA IN PATIENTS WITH DIFFERENT SKIN PHOTOTYPES

Abstract

Purpose: To assess changes in the biomechanical properties of the cornea after LASIK and FemtoLASIK at patients with different skin phototypes. The study involved 55 people (108 eyes): 25 women and 30 men aged from 18 to 49 years. On 57 eyes LASIK was performed, on 51 eyes - FemtoLASIK. Determination of the biomechanical properties of the cornea was determined by Ocular Response Analyzer II before and after surgical interventions at patients with different skin phototypes (phototype I - 14 people, II - 12 people, III - 19 people and IV - 10 people). A comparative analysis of the biomechanical properties of the cornea on the ORA II analyzer before and after excimer laser operations in patients with skin phototype I-IV showed that the magnitude of corneal hysteresis and the cornea resistance factor are weakened after the intervention, regardless of the skin phototype.
