Purpose: To compare refraction and visual acuity after SMILE operations in standard and expert modes.
Methods: The study included 2 groups of patients, 26 eyes in each. In the first group SMILE operation was performed in standard mode, in the second group - in expert mode. Refraction and visual acuity were measured before the operation, at day 1, in 1 and 3 months after the operation.
Results: UCVA before operation in the first group was 0.05 ± 0.09; at day 1, in 1 and 3 months after the operation 0.89 + 0.13; 0.93 ± 0.11; 0.94 ± 0.1, respectively. UCVA before operation in the second group was 0.05 ± 0.07; at day 1, in 1 and 3 months after the operation 0.81 ± 0.14; 0.91 ± 0.12; 0.93 ± 0.13, respectively. Spherical equivalent before SMILE in the first group was – 6.18 ± 0.78; at day 1, in 1 and 3 months after the operation 0 ± 0.16; - 0.09 ± 0.19; - 0.11 ± 0.17, respectively. Spherical equivalent before SMILE in the second group was – 6.19 ± 1.63; at day 1, in 1 and 3 months after the operation 0.09 ± 0.17; - 0.04 ± 0.14; - 0.08 ± 0.12, respectively. BCVA before operation in the first group was 0.97 ± 0.1; at day 1, in 1 month and 3 months after the operation 0.92 ± 0.11; 0.97 ± 0.09; 0.97 ± 0.1, respectively. BCVA before operation in the second group was 0.93 ± 0.1; at day 1, in 1 and 3 months after the operation 0.87 ± 0.14; 0.92 ± 0.11; 0.95 ± 0.12, respectively. There was no statistically significant difference in the obtained data between the two groups.
Conclusion: Changes of femtosecond laser working parameters from expert mode to standard mode does not influence on the obtained results of visual acuity and refraction after SMILE operation.
