  • Corneal Implant Systems and Methods
    Publication number: 20230380958
    Abstract: An example method for cutting a plurality of lenticules from a donor cornea includes receiving a donor cornea, cutting a first layer of a first set of lenticules from the donor cornea, and cutting a second layer of a second set of lenticules from the donor cornea. The lenticules are cut according to a pattern that to maximizes the number of lenticules, thereby maximizing the number of implants from the single donor cornea. An example implant handling device includes a body. The body includes a flattened end configured to receive a corneal implant and keep the corneal implant from rolling or folding. The flattened end has a width and a height, the width being greater than the height. The body includes a slit opening to the flattened end, the slit opening configured to allow the corneal implant to pass into the flattened end.
