Abstract
Purpose: to evaluate the results of symmetric binocular hypocorrection of myopia with FemtoLasik surgery in patients with presbyopia of various age groups.
Material and methods. 33 patients (66 eyes) with myopic refraction, aged 36 to 50, were operated by FemtoLasik. The intended Femto Flap thickness was 100 μm. The patients were divided into three groups depending on age; group 1 included 16 patients (32 eyes) aged 39–44, group 2 had 12 patients (24 eyes) aged 45–50, and group 3 (controls) was composed of 5 patients (10 eyes) of pre-presbyopic age (36–38 years).
Results. The symmetric binocular hypocorrection proved efficient in 35 % of cases in the group 1 and 50 % of cases in group 2. In the control group the intended and obtained values coincided in all 100 % of cases.
Conclusion. A possible cause of the discrepancy between the intended and the obtained hypocorrection effect may be a reduced corneal hydration of patients older than 39 years.
