Abstract Details

Purpose:

To analyze the effectiveness of surgical treatment of high-density nucleus cataracts using femtosecond laser in comparison with standard phacoemulsification.

Setting:

S. Fyodorov Eye Microsurgery Federal State Institution, Irkutsk, Russia

Methods:

A comparative analysis of the results of cataract treatment with a density of 4-5 by Buratto using femtosecond laser (1st group, n=12) and standard phacoemulsification (2nd group, n=14) was made. We estimated total time of ultrasound, the total equivalent power of ultrasound, the density of endothelial cells of the cornea, uncorrected distant visual acuity and the best corrected distance visual acuity.

Results:

1st group the total ultrasound time was 96.9±35.3, which was significantly less than in 2nd group 130.8±47.7 (p<0.001). Density of endothelial cells 3 months after surgery in 1st group was 2003±162.2 (p<0.001), in 2nd group – 1855.4±172.6. In first day after surgery in 1st group UDVA was 0.66±0.32, CDVA was 0.71±0.3. In 2nd group UDVA was 0.43±0.27, CDVA was 0.51±0.21. After 3 months in 2nd group UDVA was 0.64±0.29, CDVA was 0.71±0.23. Differences in visual acuity in 1st group were statistically not significant (UDVA 0.63±0.26, CDVA 0.69±0.21).

Conclusions:

Fragmentation of the dense nucleus of the lens by a femtosecond laser reduces the intensity of ultrasound and reduces the loss of endothelial cells in the intra- and postoperative period, which contributes to high visual acuity in the first day after surgery and reduces the risk of formation of endothelial dystrophy.
