Purpose

Artisan is an iris-claw intraocular lens (ICIOL) used to correct aphakia in eyes with insufficient capsular support. There is limited longitudinal data in Canada on its use in terms of safety and efficacy. The goal of this study is to evaluate long-term visual outcomes and complications following implantation of this secondary IOL at a Canadian center.

Setting

Precision Cornea Centre, Ottawa, ON, Canada

Methods

This is a descriptive retrospective chart review of patients who underwent implantation of an Artisan ICIOL at a tertiary Canadian center between January 2013 and December 2021. Clinical outcomes were assessed at standard of care post-operative follow-up visits at 1 day, 1 week, 1 month, and 3 months.
Key outcomes included uncorrected distance visual acuity (UCDVA), intraocular pressure (IOP) as well as intra-operative and post-operative complications. Data was analyzed using SAS software.

Results

73 eyes (67 patients, 51% male) were evaluated. Most common indications were IOL dislocation (n=50, 68.5%) and aphakia (n=23, 31.5%). Causes for IOL dislocation included zonular weakness (n=25, 34.2%), pseudoexfoliation (n=14, 19.2%), surgical complications (n=6, 8.2%), trauma (n=3, 4.1%), and Marfan syndrome (n=2; 2.7%). Whereas causes for aphakia included complicated cataract surgery (n=20, 27.4%), ocular trauma (n=2, 2.7%), and post-vitrectomy and lensectomy (n=1, 1.4%). Average UCDVA at pre-op (1.19±0.68) and 3-month post-op (0.65±0.60) differed significantly (p<0.05), whereas IOP did not (pre-op=16.57 mmHg, 3-month=17.52 mmHg, p=0.24). The common complication was pupil ovalization (n=11, 15.1%).

Conclusions

This is the largest retrospective study of patients who underwent implantation of the Artisan IOL in Canada. Reported outcomes demonstrated generally favourable efficacy and safety of the ICIOL as an option for providing adequate visual rehabilitation for aphakic patients without sufficient capsular support. No significant IOP changes were observed.
