An international analysis of contact lens compliance

PurposeTo evaluate compliance to contact lens use in 14 countries, and to identify wearer attributes which indicate lower compliance levels.MethodsA web-based survey was undertaken by 4021 contact lens wearers, revealing information about demographics, and lens and solution information including daily handling details, case care and aftercare frequency. Particular attention was paid to eight modifiable compliance-related behaviours which are associated with an increased risk of microbial keratitis.ResultsFull compliance was very rare for most lens users, although better (15% of wearers) for daily disposable lenses. Reduced compliance was demonstrated in South Korea, and for young male full-time contact lens users, especially those who have not consulted their eyecare practitioner for some time. The behaviours associated with the lowest levels of compliance were rubbing and rinsing, handwashing, correct lens replacement and case cleaning.ConclusionsGiven other recent literature, which suggests improved contact lens compliance with regular self-review exercises, we encourage clinical colleagues to particularly examine case cleaning, handwashing and rubbing and rinsing at aftercare examinations, especially in young male wearers.
