    Purpose. A comparative analysis of the results after conventional phacoemulsification cataract surgery (CPCS) in comparison with femtolaser-assisted cataract surgery (FLACS) at patients with implanted premium IOL in the early postoperative period and one month after surgery.

    Material and methods. A retrospective study of patients who underwent cataract phacoemulsification (44 eyes) was conducted. The average age of the patients was 52 ± 8.7 years. Two groups were identified depending on the type of operation performed. The first group included 16 patients (23 eyes) who underwent (CPCS). Uncorrected distance visual acuity (UDVA) before surgery was on average 0.24 ± 0.12 D, best corrected distance visual acuity (CDVA) 0.71 ± 2.8 D. The second group included 13 patients (21 eyes) who underwent (FLACS). UCVA before surgery was on average 0.25 ± 0.12 V, BCVA 0.93 ± 2.8 V.

    Results and discussion. In the first group, at the time of discharge, the UDVA was 0.95 ± 0.22 D, the CDVA was 0.96 ± 0.36 D. In the second group, the UDVA was 0.94 ± 0.22 D, the CDVA was 0.97 ± 0.36 D. In a month after surgery in the first group, Sphere (Sph) was –0.19 ± 0.91 D, Cylinder (Cyl) was –0.76 ± 0.55 D, UDVA was 0.73 ± 0.55 D, CDVA was 0.89 ± 1.21. In the second group, Sph was 0.03 ± 0.91, Cyl was –0.68 ± 0.55 D, UDVA was 0.70 ± 0.55 D, CDVA was 0.83 ± 1.21 D. No statistically significant difference was found between the two groups between the indicators of UDVA and CDVA and refractive data at the time of discharge and a month after surgery (p < 0.05).

    Conclusion. According to preliminary data, after surgical treatment of cataracts with traditional CDVA in comparison with FLACS, comparable results were revealed according to refraction, UDVA and CDVA in the early and long-term postoperative period. At the same time, given the small sample size, for more complete conclusions, it is necessary to continue studies with a follow-up period of at least 6 months and the inclusion of aberrometry data.
