A Study was conducted to explore demographics, disease characteristics and wear habits in cosmetic contact lens (CL)-related corneal infections in Asia that showed variable results.

Cases of CL-related corneal infection were detected prospectively from 11 centers in 8 Asian countries over a 12-month span. Case demographics, clinical features, microbiology, and compliance characteristics were contrasted between those who wore CLs for cosmetic reasons and those who wore CLs for refractive error correction.

Results
--694 CL wearers with corneal infection presented amongst which 204 were cosmetic CL and 490 were refractive CL wearers.

--Cosmetic CL infections comprised 7-54% of cases across the region. Compared with non-cosmetic CL wearers, cosmetic CLs wearers were significantly more likely to be female (90% vs 59%), young (aged less than 25, 68% vs 44%) and to have a shorter period of wear experience.

--Lenses worn by cosmetic CL wearers were more likely to be hydrogel materials and manufactured with the pigment located on the back surface of the CL.

--Presenting disease characteristics and visual outcomes were similar in both groups.

--Causative organisms were similar between the two groups, however, there was a higher rate of Acanthamoeba disease (9%) in cosmetic wearers, compared with refractive wearers (1%).

To summarize, cosmetic CL infections account for a sizable portion of CL-related infections in Asia. The majority of cosmetic CL consumers with corneal infections are young women who wear hydrogel contact lenses. The management of this population of vulnerable wearers is complicated by the availability of these goods on the internet, as well as the quality control and regulation of their sale.
