ABSTRACT
BACKGROUND:
This study aimed at measuring the effect of contact lens hygiene risk factors on the prevalence of contact lens-related keratitis and identifying the specific risk factors to both microbial and non-microbial keratitis independently.METHODS:
A cross-sectional study was conducted at Alexandria Ophthalmology Hospital from May to October 2023. All contact lens wearers attending the outpatient clinic had undergone face-to-face interviews using a standardized validated questionnaire which included demographic data and contact lenses (CLs) hygiene risk factors. Participants were classified into two groups; normal group and keratitis group. Keratitis group was further subdivided into non-microbial and microbial group.RESULTS:
The study included 245 contact lens wearers; 149 normal cases, 50 (20.4%) contact lens-related non-microbial keratitis (CLNK) cases, and 46 (18.8%) contact lens-related microbial keratitis (CLMK) cases. Sharing contact lenses and eye trauma were significant risk factors for both CLNK (p=0.036), (p=0.001) and CLMK (p=0.003), (p=0.017). CLs wear duration for more than 12 hours was associated with an increased risk of CLNK by about 4 times (p=0.030) and overnight wear of contact lenses increased the risk of CLNK by 2.6 times (p=0.030). Showering or swimming in lenses was identified as a significant risk factor for CLMK (p=0.012), moreover washing lenses with tap water increased the risk of CLMK (p=0.030).CONCLUSIONS:
Poor compliance with contact lenses hygiene rules results in a high prevalence of contact lens-related keratitis. Eye trauma and sharing contact lenses were significant hygiene risk factors for both contact lens-related non-microbial keratitis and contact lens-related microbial keratitis.
