INTRODUCTION: This study compared the efficacy of hydroxypropyl guar (HPG)/hyaluronic acid (HA) and carboxymethylcellulose (CMC)/HA lubricant eye drops for post-cataract surgery dry eye disease (DED).
METHODS: This was a prospective, open-label, assessor-masked, parallel, randomized controlled study. Seventy patients with DED who underwent cataract surgery were randomized in a 1:1 ratio to receive 1-2 drops of HPG/HA or CMC/HA lubricant four times daily for 3 weeks. Efficacy assessments included changes from baseline in corneal fluorescein staining (CFS) score, Ocular Surface Disease Index score, Schirmer's test score (without anesthesia), tear break-up time, and central corneal sensitivity at weeks 1 and 3.
RESULTS: There were 35 patients in each group. The HPG/HA group demonstrated superior improvements in CFS scores (expressed as means and standard deviations) to the CMC/HA group at week 1 ( - 1.0 [1.7] vs. - 0.1 [1.7], p = 0.039) and demonstrated comparable results at week 3 ( - 1.6 [1.8] vs. - 1.3 [1.9], p = 0.552). No statistical differences were observed in other secondary outcomes between groups at weeks 1 and 3 (p > 0.05). Only one adverse event was reported in this study, which occurred in the HPG/HA group. The AE of ocular hypertension was mild, deemed unrelated to the study treatment, and resolved within a week.
CONCLUSIONS: The HPG/HA lubricant eye drops resulted in greater CFS scores at 1 week after treatment compared with CMC/HA drops. The HPG/HA and CMC/HA drops were safe and well tolerated.
