Knowledge and Compliance among Contact Lens Wearers Living in Kuala Lumpur, Malaysia: A Cross-Sectional Study.

Abstract

Many factors determine the success of wearing contact lens, including knowledge and compliance towards lens care. This study aimed to evaluate the level of knowledge and compliance between two groups of adult contact lens wearers in Kuala Lumpur, Malaysia. A total of 60 participants aged 18-30 years old volunteered to participate in this study (30 participants prescribed contact lenses at the Universiti Kebangsaan Malaysia [UKM] optometry clinic and 30 participants fitted at private practices). Participants were interviewed using a structured questionnaire consisting of nine questions on basic knowledge related to lens wear and 13 questions on compliance, categorised into questions on the cleaning process, disinfection, accessories care and replacement schedule. All participants wore disposable contact lens 53.3% (n = 32) participants preferred using monthly disposable lenses. Both groups had the same level of knowledge, except knowledge of the effects of makeup (P < 0.000) and duration of the solution used for cleaning (P < 0.010), showing lack of knowledge on contact lenses among participants in private practices group. There were no significant differences between the groups in terms of the level of compliance with the cleaning process (P = 0.830), disinfection (P = 0.725), accessories care (P = 0.865) and replacement schedule (P = 0.699). Participants from UKM optometry clinic had better knowledge on wearing contact lens; moreover, both groups had good compliance towards lens care. Contact lens practitioners should provide all the necessary information to contact lens wearers so that they are equipped to handle contact lenses correctly, which would minimise the risk of eye complications.
