Abstract Details

Purpose:

To assess the clinical efficacy and safety of intraoperative posterior capsulorhexis as a prophylactic procedure for the development of secondary cataract in patients with axial myopia after phacoemulsification of cataracts with implantation of the posterior chamber IOL.

Setting:

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

Methods:

Retrospective analysis of 125 phacoemulsifications of cataracts with implantation of monofocal IOL and posterior capsulorhexis (1st group). The average length of the anterior-posterior axis was 25.6 �Â�± 2.4 mm, the degree of refraction (-) is 7.8 �Â�± 3.4 D. The patients' age was 57.3 �Â�± 2.7 years; 62% are women, 38% are men. Preoperative examination revealed no gross changes in the central and peripheral parts of the retina. The comparison group (2nd group) was relevant for the initial status, but after phacoemulsifications of cataracts with IOL, posterior capsulorhexis, as a prophylactic procedure, was not performed.

Results:

: In both groups in the postoperative period, uncorrected distance visual acuity was 0.75 �Â�± 0.01, in a year - 0.84 �Â�± 0.01. In 1st group, in 23 cases, in 6-12 months, a decrease in vision was detected, which was caused in 14 cases (11.2%) by retinal detachment; in 7 cases (5.6%) - macular hole; in 2 cases (1.6%) by cystic macular edema. In the second group there were no complications in these terms, and the total percentage of such complications in the long-term period did not exceed 3.5%.

Conclusions:

Phacoemulsification of cataract with simultaneous posterior capsulorhexis in patients with axial myopia is accompanied by a high incidence of complications in the posterior pole of the eyeball in the period of 6-12 months after the operation. This is probably due to the initial state of the physico-chemical properties of the vitreous body, with a subsequent disruption of the vitreous retinal interface. Therefore, for prevention of secondary cataract in these patients, it is preferable to perform other procedures: special IOL models, polishing, implantation of the intracapsular ring.
