Abstract Details


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.


Centro Hospitalar do Porto, Porto, Portugal.


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.


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.


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.
