The Bacterial and Foreign Body Contamination of Colored Contact Lenses in Warin Chamrap, Ubon Ratchathani, Thailand
Abstract
Objectives: This study aims to investigate bacterial and foreign body contamination in cosmetically monthly colored contact lenses from 4 beauty shops and a flea market in Warin Chamrap, Ubon Ratchathani, Thailand.
Methods: A cross-sectional study of colored contact lenses. The 58 samples, 11 brands and 2 vial sizes of monthly cosmetically colored contact lenses. The contact lenses and contact lenses solution was observed under light microscopic examination to find foreign bodies and other contamination. All of the colored contact lens samples underwent microbial culture using nutrient agar, a growth colony was made by biochemical tests and Gram’s staining to confirm the isolated organism.
Results: From 58 samples, the results showed bacterial growth from 4 of 58 samples in both of contact lenses and contact lenses solution in different duration from 24-72 hours. The results revealed that Bacillus sp., Staphylococcus aureus, Citrobacter sp., and Staphylococcus epidermidis were contaminated in cosmetically monthly colored contact lenses in this study. The result the foreign body also found in another vial CL solution under light microscope.
Conclusion: The study showed bacterial and foreign body contamination in cosmetically monthly colored contact lenses. This study shows that consumers should be more cautious when purchasing and caring for monthly colored CL to reduce the risks and increase the safety associated with the use of colored CL.
