Nineteen patients had test article topically administered to both eyes. Treatments were administered 2 to 4 days apart. Comfort assessments, including ocular discomfort, blurry vision, and dysgeusia assessments; ocular descriptive assessments; quality of life assessments; and overall experience questions were completed after each treatment over one hour, beginning at 90 seconds.Results: Both reproxalap formulations scored better in ocular discomfort score (ODS), blurry vision, and dysgeusia assessments than lifitegrast at each timepoint and cumulatively over all time points after instillation. There were lower rates of negative responses for both reproxalap formulations compared to lifitegrast across ocular discomfort, blurry vision, and dysgeusia assessments, and the durations of negative responses were shorter with reproxalap than with lifitegrast. The reproxalap groups experienced fewer quality of life impacts. No significant safety findings were observed following reproxalap or lifitegrast administration.Conclusion: The reproxalap eye drop experience over 1 hour after instillation was superior to that of lifitegrast. There were no statistically significant differences between reproxalap groups for ODS, blurry vision, or dysgeusia. The improved performance of reproxalap with regard to the most commonly reported side effects of lifitegrast (ie, ocular discomfort, blurry vision, and dysgeusia) may result in greater patient adherence and lower discontinuation rates.Keywords: RASP inhibitor, dry eye disease, inflammation, reproxalap, lifitegrast, eye drop comfort
