Most insurance companies cover at least a portion of cataract-related services because it is medically necessary to remove the clouded lens that is obscuring vision. That said, the amount of insurance coverage can vary from one plan to another. Your insurance may cover the cost of some diagnostic testing and the office fees for your comprehensive eye exam. The cataract surgery itself may be covered, as well as the eye drops you'll need after the procedure. Where coverage may end is at the line of a premium intraocular lens. Historically, insurance only approves the cost of a monofocal lens. Financing may be available for the remainder of costs that aren't covered by insurance.
