Abstract Details

Purpose:

To evaluate the indications, visual outcomes, and complication rate after implantation of an iris-claw intraocular lens to correct aphakia in the absence of capsule support.

Setting:

Centro Hospitalar do Porto, Porto, Portugal.

Methods:

Retrospective case series of eyes with inadequate capsular support submitted to anterior iris-fixation or retropupillary implantation of Artisan Aphakia® intraocular lens (AA-IOL) between September 2012 and June 2017.

Results:

24 eyes were analyzed, 20 with anterior iris-fixation and 4 with retropupillary implantation. The mean follow-up was 17 months (range 3-42). AA-IOL were inserted during primary surgery in 2 eyes (8.4%), during an IOL exchange procedure in 14 eyes (58.3%) and as a secondary procedure in 8 eyes (33.3%). The mean corrected visual acuity preoperatively improved significantly from 0.42 ± 0.16 to 0.26 ± 0.27 at the last visit (logMAR, p<0.01). There were no statistically significant changes in the spherical equivalent and refractive cylinder postoperatively. The most frequent complication was bullous keratopathy in 3 cases with anterior iris-fixation AA-IOL.

Conclusions:

The implantation of an iris-claw intraocular lens provided good visual outcomes. There was a relatively high incidence of bullous keratopathy with anterior iris-fixation AA-IOL. Retropupillary implantation may have a safer risk profile regarding endothelial cell loss.
