Abstract Background Blepharitis is a chronic inflammatory condition of the eyelids that affects a large proportion of patients in eye care settings. First-line treatments provide only partial relief for many patients. The BlephEx™ device provides automated eyelid debridement and aims to remove pathogenic biofilms from the eyelid margin to treat blepharitis long-term. However, evidence supporting the efficacy of BlephEx™ is limited. Methods In this double-masked randomized controlled trial, 42 patients with symptomatic blepharitis refractory to treatment were assigned to the BlephEx™ treatment or sham treatment group. Outcome measures including Ocular surface disease index (OSDI), tear break-up time (TBUT), Schirmer test, and Efron grading scale scores were assessed at baseline and after 4 weeks. A crossover design in which the treatment groups were swapped after 4 weeks was used as a recruitment tool. After receiving treatment, two patients (one per group) were lost to follow-up. Results The sham group exhibited a significant decrease in the Efron Grading Scale score. No significant differences were observed in the other outcomes between the two groups. The BlephEx™ group showed slightly greater decreases in the OSDI and Efron grading scale scores and an increase in the TBUT than did the sham group, but these differences were not statistically significant. Mild discomfort was the most common side effect and occurred equally in both groups. Conclusions No significant difference in outcomes was observed between patients who underwent BlephEx™ therapy and those who received sham treatment. BlephEx™ treatment cannot be recommended for treating blepharitis.
