Abstract
Background: The advances in contact lens and lens-care solutions, materials and design have contributed to an increase in contact lens wear, for refractive and aesthetic reasons, to about 140 million users worldwide. Contact lens wear has become increasingly popular for vision correction, yet the risk of microbial contamination remains a significant concern.
Aim and Objective: This prospective study aims to investigate the profile of microbial contamination in contact lens cases and identify potential factors contributing to the presence of microorganisms.
Material and Methods: This was a prospective study carried out in the Department of Ophthalmology and Department of Microbiology. One twenty-three contact lens cases and their case age information were collected from asymptomatic contact lens wearers. Cases of the lens were sampled at two locations, the upper rim and the lower base. The samples then underwent for microbiological investigation at Microbiology Department of Major S D Singh Medical College, Farrukhabad.
Results: In the present study out of 123 lens cases, contamination of contact lenses occurred in 56% (69 of 123) of cases. The most frequent micro-organism isolated were Coagulase negative Staphylococcus aureus (55.07%), in gram negative Pseudomonas aeruginosa (13.04%) and in fungi Candida species(7.2%) were isolated. It was also noted that a large number of gram-negative organism recovered from upper rim than the lower rim of flat well lens cases. Lens cases < 3 months of age had lower number of contamination rate than cases aged more than 9 months.
Conclusion: The findings of this research may contribute to the development of effective strategies for minimizing microbial contamination in contact lens cases, ultimately enhancing the safety and well-being of contact lens wearers.
