No significant differences in outcome were seen between anterior chamber IOLs and sutured posterior IOLs in complicated cataract extraction cases with poor capsular support, a retrospective study found.
Kendall E. Donaldson, MD, and colleagues at Bascom Palmer Eye Institute in Miami reviewed the records of 181 eyes of 181 patients that had IOL implantation with inadequate capsular support. The review covered patients from 1995 to 2001 who were implanted with either anterior chamber IOLs or sutured posterior chamber IOLs.
The postoperative complication risk ratio was 0.8 for anterior chamber IOLs compared to posterior chamber IOLs, the authors found. The most common complication experienced by patients in either group was elevated IOP, which affected 38% of those receiving anterior chamber IOLs and 42% receiving posterior chamber IOLs. Best corrected visual acuity was similar with the two lens styles. Final spherical equivalent trended toward more myopic values in the posterior chamber IOL group.
The study is published in the May issue of Journal of Cataract & Refractive Surgery.
