The objective of this study is to evaluate whether twice-daily use of Tyrvaya improves contact lens comfort in contact lens wearers.

Although more than 140 million people worldwide wear contact lenses, approximately 20% discontinue use, with discomfort being the primary reason. Contact lens discomfort is a multifactorial condition influenced by environmental factors, patient compliance, lens design, and fit, and is often associated with underlying dry eye disease. Dry eye can significantly reduce comfort and contribute to contact lens dropout.

Tyrvaya® (varenicline solution 0.03 mg) is a twice-daily nasal spray approved to relieve the signs and symptoms of dry eye disease. The objective of this study is to evaluate whether twice-daily use of Tyrvaya improves contact lens comfort in contact lens wearers.

Inclusion Criteria:

• Adult male and female subjects of any race or ethnicity who are ≥18 years of age.
• Best corrected CL visual acuity of 0.3 Logarithm of the Minimum Angle of Resolution (logMAR) or better in both eyes (Snellen equivalent 20/40).
• Soft 1-day silicone hydrogel CL wearer (daily disposable only)
• Contact Lens Dry Eye Questionnaire (CLDEQ)-8 scores (CLDEQ-8 scores ≥ 12).16
• A VAS score of ≥40 for Eye Dryness and End of Day Contact Lens Discomfort;18, 19

• Habitually wears soft CLs for a minimum of 5 days per week for 6 hours per day during the month prior to enrollment.20
• Willing to maintain habitual CL wear routine for the 3 months duration of the study.20
• Willing to only use Tyrvaya nasal spray prescription dry eye treatment for the 3 months duration of the study.
• Willing to not use any lipid containing artificial tear (AT) for the 3 months duration of the study.
• Willing to only use non-lipid containing preservative free artificial tear for the 3 months duration of the study if needed, but no more than 4 times per day; also must agree to record frequency of daily AT use if applicable.
