PURPOSE: Ocular lubricants are the cornerstone of dry eye (DE) management, key to pre- and postsurgical eye care. Blink Boost (BB) is a preservative-free lubricating eye drop developed to mimic the natural composition of tears and provide fast-acting relief for DE, even for contact lens wearers. This study assessed patient outcomes following BB use.
METHODS: This prospective, cross-sectional, US study recruited self-identified DE sufferers from a representative consumer panel. Those included had DE symptoms at screening (assessed by ocular surface disease index [OSDI]) and had used over-the-counter (OTC) artificial tears (ATs) in the past 6 months. Exclusion criteria were prescription eye drop use, ocular surgery in the past 6 months, and allergy to any BB component. Participants received a masked bottle of drops to be administered in the morning and completed a survey on product performance immediately after and at 4, 8, and 10 hours after instillation. The survey assessed global symptoms, DE-specific symptoms, and treatment satisfaction.
RESULTS: Of 622 participants, 23% were contact lens wearers, 34% used OTC ATs for allergies, and 38% for redness. Baseline OSDI severity was mild in 39%, moderate in 31%, and moderate/severe in 30%. After BB use, most participants reported immediate comfort and relief (comfortable 91%, hydrating 90%, soothing 87%, relieving 84%). Across mild (n=155), moderate (n=122), and moderate/severe (n=119) subgroups, agreement was high: “my dry eyes feel better” (88%, 86%, 87%), “these eye drops help to relieve my dry eyes” (86%, 82%, 88%), and “my dry eyes feel relieved” (88%, 82%, 88%). BB performed well across all OSDI severity levels, with notably better performance in the moderate DE cohort.
CONCLUSION: Real-world data show BB drops provide rapid hydration, comfort, and symptom relief across OSDI severities, with strongest effects in moderate DE. These findings suggest BB may offer a useful tool to support patient comfort following ocular surgery.
