Onmark Vision: Group Purchasing for Retina Practices
A GPO community that’s built by and for retina specialists.
Join us in revolutionizing community retina
Our goal is to become the largest aggregator of retina drug products in the U.S. for independent retina practices. Founded in 2024, Onmark® Vision, an exclusive group purchasing organization (GPO) program, has had an impressive start. In our first three quarters alone, the program has already reached over $1 billion in annual purchasing power.
Onmark Vision is advancing access to new therapies and superior clinical technology and support, not to mention access to the leading practice management technology: RetinaOS.

GPO Optimization
A community retina practice partnered with our Onmark® GPO experts to adopt a biosimilar therapy, saving $1 million in the first quarter and projecting $4 million annually. As a result, the practice boosted its cash flow and gained more independence, enabling it to expand by hiring another physician.
