Abstract
PURPOSE
Iris claw intraocular lenses (IOLs) were successfully used for the management of aphakia in patients that lack capsular support. The aim of this study was to compare the clinical outcome of prepupillary and retropupillary implantation of these IOLs.
METHODS
The files of the 26 patients that had an iris claw IOL implantation between 2010 and 2020 were retrospectively reviewed. Detailed ophthalmological examination findings including corrected distance visual acuity (CDVA), intraocular pressure, endothelial cell counts, slit lamp and dilated fundus examination findings were specifically tabulated. Intraoperative and postoperative complications were also specifically recorded.
RESULTS
There were 18 patients in the prepupillary implantation group and eight patients in the retropupillary implantation group. Age and gender distribution were similar between the groups. CDVA significantly increased in prepupillary and retropupillary implantation groups (p = 0.001 and p = 0.012, respectively). Median endothelial cell loss was 6.7% in prepupillary group and 7.2% in retropupillary group. The only intraoperative complication was iridodialysis (n = 1). Postoperative complications included retinal detachment (n = 1), cystoid macular edema (n = 2) and IOL tilt (n = 1). All of these complications occurred in the prepupillary implantation group.
CONCLUSION
Prepupillary and retropupillary implantation of iris claw IOLs resulted with similar visual gain and endothelial loss rates in a follow-up time of 6 months. There was an insignificant trend toward a reduced complication rate following retropupillary implantation.
