A glass intraocular lens.
We designed a glass and polyimide iris-plane, iris-clip intraocular lens. It is sterilized in the autoclave and weighs approximately 6 mg in water. The optic is 0.3 mm thick for a 19-diopter lens and the flexible haptic is 0.05 mm thick. Two identical haptics and the optic are joined mechanically to form the intraocular lens. The round spatula-like portion of an insertional instrument secures the intraocular lens by passing through two opposing flexible haptic loops and behind the optic. Fluid or air is irrigated through the cannula as the implant is inserted in order to protect the endothelium.
