Abstract Details

Purpose:

To evaluate IOL stability after FLACS and CP for subluxed lenses

Setting:

The S. N. Fyodorov Eye Microsurgery Federal State Institution

Methods:

This study enrolled patients with mild lens subluxation who underwent FLACS and CP from September 2019 to August 2020. All eyes were measured with anterior segment OCT at 4 days and 1 month after the surgery. Postoperative IOL tilt, IOL decentration, and IOL decentration angle were measured. Patients with posterior capsular tears occurred at surgery were excluded from the analysis.

Results:

This study comprised 70 eyes of 63 patients. The first group after FLACS included 35 eyes of 31 patient. The second group after CP included 35 eyes (32 patients). Best corrected visual acuity BCVA at 4 days after surgery in FLACS group was 0,14 ± 0,10 (0,00 – 0,30) log MAR and 0,17 ± 0,11 (0,00 – 0,39) log MAR in CP group. At 1 month BCVA in FLACS group was 0,09 ± 0,07 (0,00 – 0,30) log MAR and 0,16 ± 0,09 (0,00 – 0,30) log MAR in CP group. Comparative analysis between the groups yielded statistically significant differences in Tilt (pm-u = 0.001) and Decentration (pm-u = 0.001) 3 months after surgery: tilt of 6.40 ± 19.03 degrees and decentration by 0.34 ± 0.86 mm were greater in the second group.

Conclusions:

FLACS is safe and clinically effective at cataracts complicated by lens subluxation. IOL decentration and tilt are greater in CP group. In 1 month after the surgery BCVA was higher at FLACS group. Femtolaser-allows surgeons to perform capsulotomy without stretching the zonula. Further clinical studies are needed to study long-term results.
