Abstract
An intraocular device that includes a bas member is provided. The device can be an accommodation intraocular lens device with the base member and a power changing lens. The base member comprises an annular haptic that surrounds a central cavity having an open end. The power changing lens is configured to fit within the central cavity. The haptic comprises one or more projections, e.g., tabs that hold another device in position. In the case of the accommodating intraocular lens device, the other device is the power changing lens. The base member and the power changing lens are maintained separate until assembly in the eye of the patient. During assembly, the base member is advanced into the capsular bag of a patient through a capsulorhexis and oriented such that the open end of the central cavity faces the cornea. Subsequently, the power changing lens is advanced into the central cavity through the capsulorhexis. The one or more tabs are placed anterior of the power changing lens to secure the power changing lens within the cavity.
