Abstract Details

Purpose:

Iris-fixated IOLs are considered a safe and effective option for the correction of aphakia in patients with insufficient capsular support. Nowadays, Artisan/Verisyse IOL (Ophtec BV, Groningen, The Netherlands) is the most popular model of iris-fixated IOL. Originally, this IOL was designed for a pre-pupillary fixation. However, a retro-pupillary fixation of the IOL is also possible. 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.

Setting:

Department of Ophthalmology, Elche’s University General Hospital.

Methods:

Three different databases were used for this systematic review (PubMED, Scopus and Embase). Inclusion criteria were case series or clinical trials performed on aphakic patients with insufficient capsular support and with an Artisan or Verisyse lens implantation. The following variables were analyzed: age, follow-up, pre- and postoperatory corrected distance visual acuity (CDVA), pre- and postoperatory spherical equivalent (SE), pre- and postoperatory intraocular pressure (IOP), pre- and postoperatory central corneal cell density (CECD), postoperatory cystoid macular edema (CME), pupil deformation and IOL luxation. The statistical analysis was performed with the programming language R (version 3.6.1 2019-07-05).

Results:

The number of articles included in the metanalysis was 6, with 506 eyes included in total. Mean age was 67.24 years and 69.79 for the pre- and retro-pupillary implantation position respectively (p = 0.46). We found no significant differences in postoperative CDVA (0.309 (0.089-0.528) vs 0.32 (0.2-0.44)), SE (0.0153D (-0.362-0.393) vs -0.329D (-0.62;-0.038)), CECD (1669.85 cells (1605.949-2150.937) vs 1635.99 cells (1413.64-1858.363)) between the pre- and the retro-pupillary implantation respectively. There weren’t significant differences between the rates of CME (7.70% vs 9.8%), pupil deformation (4.5% vs 5.4% retro-pupillary) or IOL luxation (2.3% and 2.2%).

Conclusions:

We found a low influence of the IOL position on the postoperative analyzed outcomes. Thus the implant position should be based on the surgeon’s technical experience. Since the retro-pupillary implantation technique is easier and avoids the realization of an iridotomy to prevent pupillary block, the realization of a retro-pupillary fixation through a scleral tunnel may be suggested as the standard surgical procedure for Artisan-Verisyse implantation.
