The biggest breakthrough in your field over the last couple of decades…

The single biggest breakthrough was the appropriate delineation of our Medicare and private insurance system in 2005, and the separation of medical and refractive aspects to cataract surgery. This paradigm shift allowed patients to pay separate premiums for refractive IOLs while still receiving coverage for the medical procedure, providing fair compensation to industry and ophthalmologists for their products and services. It also gave patients access to improved refractive technologies and outcomes, while elevating the refractive skills of cataract surgeons.
