Posterior iris-claw aphakic intraocular lens implantation in subluxated lenses due to Marfan syndrome.

Abstract

PURPOSE:

To evaluate the indications, visual outcomes, and complication rate after posterior implantation of an iris-claw aphakic intraocular lens (IOL) in subluxated lenses due to Marfan syndrome.

METHODS:

Eyes without adequate capsular support had posterior chamber iris-claw aphakic IOL implantation between 2006 and 2012.

RESULTS:

This retrospective cohort study comprised 13 eyes of 10 patients (7 female, 3 male; mean age ± standard deviation, 34.7 ± 19.6; range 9-61 years). The mean follow-up was 37 months (range 6-74 months). The mean final postoperative best-corrected visual acuity was significantly (0.24 ± 0.36 logMAR) better at the last follow-up than 1 day preoperatively (0.72 ± 0.46 logMAR) (p<0.05). There was no significant change in intraocular pressure before and after surgery. The mean endothelial cell density decreased from 2793 ± 478 cells/mm2 preoperatively to 2637 ± 612 cells/mm2 at last follow-up, representing a mean endothelial cell loss of 5.6%. Complications included early transient postoperative hypotony in 2 eyes (15.4%), slight persistent pupil ovalization in 1 eye (7.7%), and retinal detachment in 1 eye (7.7%).

CONCLUSIONS:

The posterior implantation technique of aphakic iris-claw IOL provided good visual outcomes with a favorable complication rate and can be used as a reasonable alternative in subluxated lenses due to Marfan syndrome without adequate capsular support.
