A cross-sectional study on contact lens case hygiene: awareness and compliance among tertiary eye care patients

Abstract

Aim: This study aimed to assess patient compliance with contact lens storage case (CLSC) hygiene, focusing on cleaning practices, replacement frequency, and storage methods. It also evaluated the type of instructions received from eye care professionals and the overall awareness of CLSC care among wearers visiting a tertiary eye care hospital.

Method: A cross-sectional study was conducted using a custom-designed, self-reported questionnaire developed in Google Forms to collect information on contact lens use, storage case hygiene practices, replacement habits, and adherence to recommended care protocols. The survey was disseminated via email and social media platforms and administered to 103 participants before leaving the outpatient department. Collected responses were analyzed to identify patterns, compliance levels, and associated risk perceptions.

Results: A total of 103 participants (age range: 16–32 years; mean: 24.68 ± 3.33 years) were included. Most used monthly replacement silicone hydrogel lenses and multipurpose solutions (MPSs). While 78.6% reported cleaning their cases, 21.4% did not. MPS was the most common cleaning agent (39.8%), though 18.4% used water and soap. Only 18.4% replaced their cases monthly, and 25.2% every 1–3 months. Of those who received guidance (93.2%), 44.7% received it orally, while 15.5% were unsure of the format. Perceived risk was significantly associated with gender (P < 0.001 for hand washing) but not with education level or case cleaning (P > 0.5).

Conclusion: Despite general awareness of hygiene risks, significant gaps in compliance persist.
