Rate of Complete Spectacle Independence with a Trifocal Intraocular Lens: A Systematic Literature Review and Meta-Analysis

Abstract

Abstract Introduction A systematic literature review and meta-analysis was conducted to identify and obtain a precise single summary estimate on complete spectacle independence after bilateral implantation of a trifocal intraocular lens (IOL) (AcrySof PanOptix, TFNTXX/TFATXX) for patients undergoing cataract surgery. Methods A search was conducted in PubMed from January 2017 to September 2021. Relevant congress presentations were also searched to include data from completed studies not yet published. Search terms included the intervention (TFNTXX, TFATXX, PanOptix) and outcomes of interest (patient-reported spectacle independence rates). A Bayesian random-effects meta-analysis was conducted, providing a pooled estimate (median and its 95% credible interval) of complete spectacle independence rates among cataract surgery patients. Subgroup analyses evaluated spectacle independence after cataract surgery across different working distances (near, intermediate, far). Results Nineteen unique clinical studies were identified. Based on a meta-analysis of 13 studies (N = 513 patients), the complete spectacle independence rate after cataract surgery with TFNTXX/TFATXX IOL was 91.6% (95% credible interval 86.8–95.9%). Additionally, the spectacle independence rates at each focal point (N = 13 studies, 603 patients) were 89.6% (near), 96.3% (intermediate), and 95.9% (far). Conclusions This meta-analysis demonstrated that at least nine out of ten patients receiving TFNTXX/TFATXX trifocal IOL during cataract surgery can expect to achieve complete spectacle independence. This study provides informative data for clinicians and patients to feel confident in the use of trifocal intraocular lenses as presbyopia-correcting IOLs that offer high rates of complete spectacle independence.
