Abstract
Purpose :
Actually the most feared complication by ophthalmologists of contact lens (CL) wear is microbial keratitis (MK), even though its incidence remains low. It’s also a huge financial burden for the society. This study aimed to identify the risk factors of CL-related MK especially for hygiene and type of use, in a large prospective, multi center case-control study.
Methods :
A multicenter case-control study was designed. The CL related MK subpopulation (Case) was compared with healthy CL wearers (Control) using a 52-item anonymous questionnaire designed to determine subject demographics, lens wear history, lens type and disinfection solution. Univariate logistic regression analyse was performed to compare both groups.
Results :
The study enrolled 497 cases and 364 controls.
Conclusions :
The risk factors associated with the greatest increased odds of CL-related MK were as follows: extended wear, adaptation by an ophthalmologist, no follow-up, use of optician’s disinfection solution, no case replacement . The protective factors associated with the greatest reduction in OR were fitting by an ophthalmologist, female gender, hypermetropia and written and oral informations.
