AIM: To evaluate the effect of capsular tension rings with multifunctional lens position and optical outcomes. METHODS: We de ned multifunctional lens more than improve vision, but also restore visual quality. Search of PubMed, EMBASE, Cochrane Library. Scopus for English-language articles published up to November 11, 2020. Randomized controlled trials and comparative prospective clinical trials were selected. Data extraction was completed by independent pairs of reviewers. Risk of bias was evaluated using the Cochrane Collaboration risk of bias tool for RCTs and select items from the Newcastle-Ottawa Scale for comparative prospective clinical trials.RESULTS: a total of 5 randomized controlled trials and 6 prospective comparative clinical trials were included. Evaluating 1099 eyes of implantation intraocular lens. Capsular tension ring was helpful associated in un-corrected distance visual acuity (SMD: 0.54, 95%CI=0.15 to 0.94, P=0.829) in 1 st month. Contrary to 1 st month, no show positive effect in 3 rd month un-
Purpose: For analysis, clinical outcomes of phacotrabeculectomy versus phacoemulsification in glaucoma coexist cataracts.Methods: we screened only randomized controlled trials comparing clinical outcomes of Phacotrabeculectomy versus Phacoemulsification published before October 2021. Then, we pooled qualified articles for meta-analysis. We estimated pooled weighted mean difference and risk ratio with 95% conference intervals. We conducted fixed-effects models in this meta-analysis.Results: We pooled 10 randomized controlled trials to Meta-analysis. Phacotrabeculectomy has a superior effect in postoperatively intraocular pressure and postoperative anti-glaucoma medications versus phacoemulsification, but an equal effect in best-corrected visual acuity. The complication ratio of phacotrabeculectomy is higher than phacoemulsification. Our article just presented all views of visual fields of included articles because of insufficient data to analyze.Conclusions: Phacotrabeculectomy is more efficient compared to phacoemulsification in glaucoma coexisting cataracts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
