There is disclosed a system for use in preparing a lenticular or corneal implant for delivery to an operating site and insertion into a recipient's eye. The system includes a cartridge 16 having a generally tubular portion including a sidewall defining a longitudinal bore, of curvilinear cross section, having open forward and rearward ends; a preparation base 18 comprised of a lower portion and an upper portion, the upper portion having a recess 200 and removably engaging the cartridge 16; and an insert member 100 removably engaging the base in the recess and defining a platform for receiving the implant, and a portion adjacent the platform defining a funnel structure 101 having a wider end facing the platform, and a narrower end facing the open rearward end of the cartridge 16 when the system is assembled. In use, a corneal implant is pulled through the funnel 101 into the cartridge, the tapering of the funnel folds it into a double coil or cardioid shape. The handle is attached, and the device is inserted through a scleral tunnel into an anterior chamber of the eye. |
