The influence of the Artisan-Verisyse position on the postoperative outcomes: A systematic review and meta-analysis.

Abstract

Iris-fixated intraocular lens (IOL) is considered a safe and effective option for the correction of aphakia in patients with insufficient capsular support. This systematic review aims to summarize the existing evidence about the Artisan/Verisyse IOLs and to assess the influence of the IOL position on the postoperative outcomes. Three different databases were used for this systematic review and metaanalysis (PubMED, Scopus, and Embase). We searched for case series or clinical trials comparing the prepupillary versus retropupillary Artisan/Verisyse implantation. The statistical analysis was performed with the programming language R (version 3.6.1 2019-07-05). The number of articles included in the meta-analysis was six, with 506 eyes included in total. We found no significant differences in postoperative corrected distance visual acuity (CDVA) (0.309 [0.089-0.528] vs. 0.32 [0.2-0.44]), spherical equivalent (SE) (0.0153 D [-0.362 to 0.393] vs. -0.329 D [-0.62 to - 0.038]), and central corneal cell density (CECD) (1669.85 cells [1605.949-2150.937] vs. 1635.99 cells [1413.64-1858.363]) between the prepupillary and the retropupillary implantation, respectively. There were no significant differences in the rates of cystoid macular edema (CME; 7.70% vs. 9.8%), pupil deformation (4.5% vs. 5.4% retropupillary), or IOL luxation (2.3% and 2.2%). We found little influence of the IOL position in the postoperative analyzed outcomes. Thus, the implant position should be based on the surgeon's technical experience. Double-blind randomized prospective studies would improve the available evidence on the best implant position for the Artisan/Verisyse IOL.
