[Results of hybrid (femtosecond laser-assisted) phacoemulsification of hypermature cataract in patients with lens subluxation].

UNLABELLED

Studying the use of femtosecond laser in patients with complicated cataracts remains a topical issue in phaco surgery.

PURPOSE

To comparatively analyze the results of using hybrid (femtosecond laser-assisted) phacoemulsification in hypermature cataract in patients with lens subluxation.

MATERIAL AND METHODS

The study included 78 patients (78 eyes) with hypermature cataract in combination with lens subluxation of I-II degree. In the 1 group (45 eyes) capsulorhexis was performed using a femtosecond laser. In the 2 group (33 eyes) manual capsulorhexis was performed.

RESULTS

On the first day after surgery, best corrected visual acuity of 0.8-1.0 was obtained in 57.8% of cases in the 1 group and 33.3% in the 2 group. Transient corneal edema during the first 1-3 days was noted in 4.4% of cases in the 1 group and in 15.2% - in the 2 group of patients. Pachymetry in the center of the cornea showed an increase in its thickness on the 1 day after surgery from 0.564±0.027 mm to 0.591±0.033 mm in the 1 group and from 0.561±0.023 mm to 0.637±0.043 mm (<0.05) in the 2 group of patients. The loss of corneal endothelial cells amounted to 10.9±1.8% in the 1 group and 17.4±2.9% in the 2 group (<0.05). Macular edema with decreased visual acuity confirmed by OCT was detected in the 1 group of patients in 2.2% of cases, in the 2 group - in 9.1% of cases. With a follow-up period of up to 3 years, IOL optics decentration by more than 1 mm was detected in 2.2% of cases in the 1 group of patients and in 12.1% of cases in the 2 group.

CONCLUSION

Femtosecond laser-assisted capsulorhexis significantly improves the results of surgery in patients with hypermature cataract combined with lens subluxation.
