ABSTRACT

CLINICAL RELEVANCE: This study found 0.7% olopatadine (Pataday Once Daily Relief Extra Strength) eye drops to provide better initial comfort than 0.3% pheniramine maleate/0.025% naphazoline hydrochloride (VISINE® Allergy Eye Relief Multi-Action Antihistamine and Redness Reliever) eye drops suggesting that patients may comply better with the Pataday than VISINE. BACKGROUND: To compare the ocular comfort at instillation of Pataday and VISINE allergy eye drops. METHODS: Minimally symptomatic participants were recruited based upon Standard Patient Evaluation of Eye Dryness (SPEED) questionnaire scores (≤3 units); they also had minimal between-eye inter-ocular comfort differences as judged by visual analogue scale scores (VAS; ≤7 units). Baseline comfort was evaluated by eye with a VAS. One drop of Pataday or VISINE was then applied to the right eye with the alternative drop being applied to the left eye. The same VAS evaluated comfort by eye at drop instillation, and then at 30 seconds, 1 minute, and 2 minutes post-instillation. Drop experience was also evaluated with Likert questions. LogMAR visual acuities and bulbar conjunctival redness were evaluated pre- and post-drop instillation. RESULTS: A total of 159 participants were recruited (mean ± SD age = 26.2 ± 7.5). The VAS found that eyes treated with Pataday were significantly more comfortable at instillation than eyes treated with VISINE. Likert questions indicated that participants significantly preferred Pataday drops compared to the VISINE drops at instillation with regards to overall eye comfort, eye stinging, eye burning, and foreign body sensation. There were no between drop differences in visual acuity, though eyes treated with VISINE were less red than eyes treated with Pataday. CONCLUSIONS: Topically applied Pataday drops were more comfortable than VISINE drops.

ABSTRACT

PURPOSE: To compare the ocular comfort at application of topical, over-the-counter, 0.7% olopatadine and 0.035% ketotifen fumarate anti-allergy eye drops. METHODS: This study recruited participants who were minimally symptomatic based upon Standard Patient Evaluation of Eye Dryness (SPEED) questionnaire scores (≤3 units) and who had minimal between-eye inter-ocular comfort differences as judged by visual analog scale scores (VAS; ≤7 units). Baseline comfort was evaluated by eye with a VAS. One drop of 0.7% olopatadine or 0.035% ketotifen fumarate was then applied to the right eye with the alternative drop being immediately applied to the left eye. Participants were next evaluated with the same comfort VAS by eye at drop application, and then at 30 s, 1 min, and 2 min post-application. LogMAR visual acuities and bulbar conjunctival redness were evaluated pre- and post-drop application to judge initial changes. RESULTS: This study enrolled 159 participants who had a mean ± SD age of 26.3 ± 7.7 years, and 78.6% of the participants were female. The VAS found that the 0.7% olopatadine drop was more comfortable than the 0.035% ketotifen fumarate drop at all time-points. There were no between-eye differences in LogMAR visual acuities, yet bulbar redness was significantly less in 0.7% olopatadine treated eyes compared 0.035% ketotifen fumarate treated eyes. CONCLUSION: This study found that topically applied 0.7% olopatadine drops were initially more comfortable than 0.035% ketotifen fumarate drops.
