To assess visual outcomes, macular changes and complication rate after implantation of a posterior chamber iris-claw aphakic intraocular lens (IOL).
Eye Hospital, University Medical Centre Ljubljana, Ljubljana, Slovenia.
This retrospective analysis included 11 aphakic eyes that underwent a retropupillary iris-claw (Verisyse) lens implantation between January 2010 and December 2013. Collected data included demographics, etiology of aphakia and previous surgeries. The main outcome measures were changes in best-corrected visual acuity (BCVA), central macular thickness (CMT) evaluated with optical coherence tomography (OCT), intraocular pressure (IOP) and complications.
Ten patients were included. In five patients the IOL was implanted in right eye, in four patients in left eye and in one patient in both eyes. Eight patients were male and two female. Mean age was 62.7 years (range: 27-80) years). Mean follow-up was 23 months (range: 6 to 48 months). Mean preoperative BCVA was 0.22 on Snellen charts (range: 0.01-0.7). Postoperatively, mean BCVA improved to 0.61 (range: 0.01-1.0) (p<0.05). Two patients had low visual acuity preoperatively because of pre-existing eye pathologies. Mean preoperative CMT was 255, 27 μm (range: 144-375 μm). Mean postoperative CMT was 264, 54 μm (range: 111-386 μm) (p>0.05). Mean CMT of the non-operated eye was 235, 63 μm (range: 189-434 μm) (p>0.05). Mean preoperative IOP was 17.3 mmHg. Mean postoperative IOP was 13.7 mmHg (p>0.05). After the surgery, in two patient’s slight pupil ovalisation occurred. No other complications were noticed during follow-up period.
Retropupillary iris-claw (Verisyse) lens implantation is clinically safe and effective to correct aphakia in eyes without capsular support. In this small group of patients there was no statistically significant increase in CMT after the surgery.
