A system for use in preparing a lenticular or corneal implant includes a cartridge having a generally tubular portion, comprised of a sidewall defining a longitudinal bore of curvilinear cross section and having open forward and rearward ends. The system also includes a preparation base with an upper portion having a recess and cartridge-receiving structure for removably engaging the cartridge in position with the open, rearward end of the longitudinal bore thereof proximate one side of the recess, allowing for facile removal of the cartridge from the base. An insert member has structure for removably engaging it in the recess, and has one portion defining a platform for receiving the implant and another, adjacent portion defining funnel structure having a wider end facing the platform and a narrower end facing the open rearward end of the cartridge.
