Abstract Details

Purpose:

Comparison of clinical outcomes of digital and manual marking for toric intraocular lens (TIOL) alignment.

Setting:

109147, Moscow, Marksistskaya str. 3/1, Excimer Eye Centre, kpershin@mail.ru

Methods:

A prospective study included 64 patients (75 eyes) with a combination of cataract and corneal astigmatism, who underwent cataract phacoemulsification and TIOL AcrySof® IQ Toric Natural IOL SN6AT2-T9 implantation. Group I consisted of 17 patients (17 eyes) with digital marking on VERION ©. Group II included 43 patients (54 eyes) who underwent manual alignment of TIOL during biomicroscopy using a pendulum marker. The observation period of the patients was 1±0.2 months in group I and 7.9±1.3 months in group II.

Results:

Mean postoperative UCDVA in group I was 0.79±0.04 compared to 0.87±0.09 in group II. In group I in 94.1% in UCDVA 0.5 or higher was determined, in group II in 88.9%. In none of the groups loss of lines when measuring visual acuity was detected, BCVA 0.5 or higher was achieved in 100% of cases. In group I, mean deviation from TIA was 0.08±0.05 diopters, in group II 0.26±0.07 diopters, differences are significant (t=2.09;p=0.046). In the first group, 100% of the deviation from TIA did not exceed 0.5D, in the second group - 98.1%. Mean misalignment of postoperative TIOL axes in group I was significantly lower than in group II (3.18o±0.43o vs 7.04o±0.96o, respectively;t = 1.92;p=0.031).

Conclusions:

First results of VERION© system use in Russian patients undergoing toric IOL alignment are presented. VERION© system has the advantage of preoperative planning and intraoperative digital guidance of the toric IOL alignment. The use of VERION system resulted in less postoperative deviation from TIA and showed less postoperative toric IOL misalignment than using manual-marking technique.
