Abstract

This invention discloses devices for use with an ophthalmologic insertor apparatus. In one embodiment, the device is a flexible, stretchable sleeve holder adapted to fit over a deformable sleeve that houses an implant. The sleeve holder facilitates loading of an implant into the sleeve by providing a suitable gripping surface. Application of a compressive force to the sleeve holder further allows the implant to be immobilized within the sleeve. After loading of the implant into the sleeve, the holder may be used as a collar or hub to secure the sleeve to an insertor hand-piece. Methods for loading implants into delivery sleeves, methods for attaching sleeves to inserters, and methods for delivering implants to an incision are also disclosed.
