Ora-CAC® Allergen Model

For decades, the Ora Conjunctival Challenge Model (Ora-CAC®) has been used to evaluate every anti-allergic agent for the treatment of allergic conjunctivitis and is the gold standard for FDA approval of ocular allergy treatments.

While environmental studies continue to be used for the assessment of anti-allergic agents, the precision of the Ora-CAC® model study design allows for a more predictive and rapid study, with fewer patients, fewer sites, and a tighter dataset.

Allergen BioCube®

The Allergen BioCube® is Ora’s proprietary clinical model used in trials for allergic rhinitis and conjunctivitis. It is a versatile allergen exposure chamber that can be stationary or mobile, meticulously releasing measured pollen amounts for consistent and controlled exposure. It’s effective for solo use or combined with other models to confirm the efficacy of treatments in critical studies.

In simulating pollen exposure, Ora ensures accuracy with real-time laser detection of airborne aeroallergens, creating an exposure experience that mirrors natural conditions, triggering real allergy symptoms in patients.

For over 45+ years, Ora has been on the leading edge of ophthalmic product development.
