The Risk of Blepharoptosis in Contact Lens Wearers

초록

Purpose : Many plastic surgeons think that prolonged contact lens wear potentially causes acquired ptosis. Although several papers been written, only 1 study attempted to determine the risk of developing blepharoptosis due to wearing hard contact lenses. The aim of this systematic review was to summarize and evaluate the risk of blepharoptosis in contact lens wearers. Methods : In a PubMed search, 393 papers were found using the terms ‘‘lens and ptosis.’’ The abstracts were read and 16 full text articles were reviewed. Among them, 5 articles were analyzed (Fig. 1). No restrictions on language and publication forms were imposed. However, the resulting full text papers were mostly in English. All articles were read by 2 independent reviewers who extracted data from the articles. To summarize the effect of contact lens use on blepharoptosis, the data were summarized and the odds ratio (OR) between the contact lens wearers and nonwearers (control group) were calculated. Weighted mean differences (WMD) and 95% confidence intervals (CI) were also calculated. A statistical analysis was performed with Review Manager. In case the number of nonwearers was not written in the paper, it was calculated from the percent of the wearers and nonwearers of the general population of the nation reported.
