Secondary implantation of angle-supported lens in the anterior chamber versus iris-suture-fixated lens

Abstract

Objective: Compare the results of secondary implantation of rigid angle-supported intraocular lenses in the anterior chamber versus foldable iris-suture-fixated intraocular lenses in the posterior chamber, in terms of effectiveness, safety and vision-related quality of life (questionnaire NEI VFQ-23).
Methods: A quasi-experimental study was conducted of 50 eyes of aphakic patients without capsular support after cataract surgery, who were divided into two groups according to the treatment indicated.
Results: It was found that in the group treated with iris-suture-fixated intraocular lens implantation the percentage of patients with 20/40 vision or more was significantly higher (96.0 vs. 60.0%, p = 0.000), whereas the results of the quality of life questionnaire were lower in terms of frequency of patients with 20/200 vision or less (0.0 vs. 16.0%, p = 0.110), induction of astigmatism, endothelial cell density reduction (361.6 ± 220.5 vs. 556.1 ± 340, p = 0.021) and percentage of patients with complications (36.0 vs 52.0%, p = 0.254).
Conclusions: Better results were obtained with the implantation of foldable iris-suture-fixated intraocular lenses.
