Sight Sciences TearCare System Cleared

Sight Sciences has received the FDA’s 510(k) clearance for its TearCare System to treat meibomian gland dysfunction (MGD), the leading cause of dry eye disease.

The system delivers localized heat therapy, in conjunction with manual tear gland expression, to help soften or liquify meibum, the lipid-rich secretion that helps keep eyes moist.

The device is designed to deliver a consistent level of therapeutic heat (45 degrees Celsius) to the outer surface of the eyelids to maintain an inner eyelid temperature of 41-42 degrees Celsius — the inner eyelid temperature necessary to melt meibum.
