Dry Eye Disease ™
Dry Eye Disease and Meibomian Gland Dysfunction MEIBOMIAN GLANDS Dry Eye Disease (DED) can be extremely painful and can lead to permanent cornea damage and vision impairment MGD is present in the vast majority of diagnosed dry eye cases, linked to many prominent demographic, medical and sociological trends Clogged glands prevent meibum, an oily secretion that protects tears from premature evaporation, from reaching the tear DED treatment historically focused on aqueous deficiency and inflammation 38 million affected in U.S. (17 million diagnosed) 86% of DED caused by MGD $10 Bn U.S. TAM, hugely underserved 0% meaningful reimbursement for MGD procedures 13
Our Solution: TearCare® The Only Wearable Eyelid Technology designed to melt + remove meibomian gland obstructions Intuitive Design Designed for intuitive provider training and comfortable patient experience SmartLids™ are designed to conform to variable eyelid anatomy and heat glands to a proven temperature to “prime” meibum through natural blinking Eyelid Therapy for Evaporative Dry Eye In patients with MGD, meibum hardens within the meibomian glands and forms obstructions TearCare delivers software and sensor-controlled, precise (41° C at the inner eyelid) and consistent (15 minutes) heat that has been clinically proven to melt gland obstructions Enables manual gland clearance by an ECP 14
TearCare® Cleared by FDA December 2021 December 2021 Indication for Use “For the application of localized heat therapy in adult patients with evaporative DED due to MGD, when used in conjunction with manual expression of the meibomian glands” Considerable benefits from expanded indication for use Reduce IOP in adult patients with POAG across the spectrum of disease severity Key step toward achieving ultimate IFU goal: treat signs and symptoms of DED due to MGD Significant improvement over prior “tool” claim backed by robust clinical data; specifically mentions heat therapy and manual expression Enhances promotional capabilities: marketing collateral and sales reps can now explicitly address all key attributes of the TearCare System Allows patients and ECPs to have more intuitive understanding of the TearCare System’s ability to treat DED due to MGD Supported by favorable safety and efficacy data from our OLYMPIA RCT 15
