Abstract Details

Purpose:

To assess the feasibility of performing a primary posterior capsulorhexis (PPC) in patients with implantation of bifocal IOLs.

Setting:

Eximer eye center, Moscow, Russian Federation.

Methods:

A total of 34 (40 eyes) patients were examined and treated. Men accounted for 44.1%, women - 55.9%. The average age of the patients was 57.1 ± 7.0 years. In all investigated cases, a complex preoperative examination was performed. The phacoemulsification was performed using Stellaris and Infinity microsurgical systems through a corneal temporal tunnel incision of 1.8-2.0 mm.

Results:

We present our own technique of PPC, including the use of two types of viscoelastics and the implementation of capsulorhexis after implantation of the IOL. In all cases, the bifocal IOL Acrysof IQ Restor was implanted, the target refraction was ±0.25 D. The observation period was 13.4±10.2 months. An increase in the UCVA from 0.13 ± 0.11 to 0.85 ± 0.21 in the distance and 0.77±0.21 near, BCVA from 0.25±0.20 to 0.93 ± 0.13 in the distance and 0.83 ± 0.21 near 6 months after surgery (p < 0.05). Reduction of the spherical and cylindrical component of refraction is shown.

Conclusions:

The data obtained indicate the safety and effectiveness of the proposed method. To determine the indications and contraindications it is necessary to conduct a comparative study with patients with a preserved posterior capsule of the lens and multifocal correction.
