Effect of the Bruder moist heat eye compress on contact lens discomfort in contact lens wearers: An open-label randomized clinical trial.

The purpose of this study was to investigate the effect of the Bruder Moist Heat Compress on contact lens (CL) discomfort in subjects with contact lens-related dry eye (CLDE). This was a 4-week, single-center, three-arm, randomized, open-label clinical trial in subjects diagnosed with CLDE using the Contact Lens Dry Eye Questionnaire. Fifty-one CL wearers were randomized to one of three treatment groups: application of the Bruder Compress twice a day, Bruder Compress once a day, or warm washcloth used for ten minutes twice a day without reheating. Subject diaries were monitored for compliance and collected data on daily CL comfort upon awakening and throughout the afternoon. Clinical assessments included tear film break-up time (TBUT), lipid layer thickness (LLT), and meibomian gland evaluation. Statistical tests included a generalized linear model and one-way analysis of variance (ANOVA) to investigate treatment effect on comfortable wear time. Fifty-one subjects (98% female) completed the study. After treatment, subjects using a washcloth reported more uncomfortable contact lens wear time on average (mean = 5.1 ± 2.8 h) when compared with subjects who had used the Bruder Compress in Group 1 (mean = 2.8 ± 1.6 h) (p = 0.02). In the Bruder Compress groups, there was a significant reduction in the blockage of meibomian glands (p < 0.01). No significant difference in uncomfortable wear time was found between subjects using the Bruder Compress twice daily versus once daily (p = 0.48). Subjects using the Bruder Compress once daily had the highest rate of compliance at 90.2% (p < 0.01). No significant improvements were observed in TBUT (p = 0.76) or LLT (p = 0.78). The Bruder Moist Heat Compress resulted in a significant improvement in comfortable CL wear time in subjects with CLDE.
