Matrix metalloproteinase-2 (MMP-2) polymorphisms have been considered as risk factors of cataracts, but the results still remain controversial. In this study, we have performed a systematic meta-analysis to evaluate the association between MMP-2 polymorphisms and cataract risks. Published literature was retrieved from Wanfang, Chinese Biomedical Literature Database, Chinese National Knowledge Infrastructure, Chongqing VIP Chinese Science and Technology Periodical Database, PubMed, Embase, and Web of Science databases. The case-control studies that explored the association between MMP-2 polymorphisms and cataract risks were included. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using random- or fixed-effects model. This study could provide high-quality and evidence-based medical evidence for the correlation between MMP-2 polymorphisms and cataract risks. The study could provide updated evidence for the evaluation of the relationship between MMP-2 polymorphism and cataract risk. The private information from individuals will not be published. This systematic review also will not involve endangering participant rights. Ethical approval is not available. The results may be published in a peer-reviewed journal or disseminated in relevant conferences. DOI 10.17605/OSF.IO/KU9NE. Copyright © 2021 the Author(s). Published by Wolters Kluwer Health, Inc.
