The Risk of Blepharoptosis in Contact Lens Wearers

The aim of this systematic review was to summarize and evaluate the risk of blepharoptosis in contact lens wearers. 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. Five studies were subgrouped and a meta-analysis of these data suggested there is an increased risk of blepharoptosis in hard contact lens wearers over nonwearers (n = 7426, OR, 17.38, 95% CI = 3.71-81.29, P < 0.00001). One study was subgrouped and these data suggested there is also an increased risk of blepharoptosis in soft contact lens wearers over nonwearers (n = 90, OR, 8.12, 95% CI = 2.68-24.87, P < 0.0002). Patients wearing rigid contact lenses should be advised of the risk of ptosis, and a history of contact lens use should be sought in all patients who have acquired ptosis as the previous authors have recommended.
