Retropupillary iris-claw intraocular lens implantation in aphakic patients.

To evaluate the outcomes of implantation of an iris-claw intraocular lens (IC-IOL) in retropupillary position in aphakic patients. We conducted a prospective interventional study, including 36 aphakic eyes with inadequate capsular support. The postoperative examination included best-corrected visual acuity (BCVA), intraocular pressure (IOP) measurement, central corneal thickness (CCT), and anterior segment examination with emphasis on the anterior chamber reaction and shape of pupil. Follow-up was done for 3 months. Thirty-six eyes of 34 patients, including 22 right eyes and 14 left eyes were included. Indications for surgery were complicated cataract surgery in 38.9% (n = 14), aphakia in 27.8% (n = 10), pseudophakic bullous keratopathy in 16.7% (n = 6), dislocated posterior chamber IOL (PCIOL) in 11.1% (n = 4), IC drop in 2.8% (n = 1), and subluxated PCIOL in 2.8% (n = 1). Postoperatively, the visual acuity improved by at least two lines in 32 (88.9%) and worsened in four (11.1%) eyes at the end of three months. Mean postoperative IOP at the end of the third month was 12.42 mmHg (standard deviation [SD] 2.57; range 11.55-13.29 mmHg). The mean postoperative CCT at the end of the third month was 542.42 microns (SD 13.77; range 537.76-547.07 microns). Sixteen eyes (44.4%) had horizontally oval pupil, eleven eyes (30.6%) had round pupil, and nine eyes (25%) had irregular pupil. Twenty-three eyes (63.9%) presented with significant anterior chamber reaction and seven eyes (19.4%) had corneal stromal edema on postoperative day 1. Our study demonstrated that retropupillary IC-IOL implantation in eyes without adequate capsular support is an effective and safe procedure with a good visual outcome and fewer complications.
