Abstract
In an ophthalmic surgical laser system, a patient interface device for coupling a patient's eye to the laser system includes a lens cone with a frustoconical shaped shell for coupling to the laser system and a suction ring for coupling to the patient's eye, the lens cone and the suction ring being joined together by clamping. A cap is provided for use with the lens cone as an installation aid. In the configuration supplied to the user, the lens cone is partially embedded in and snapped to the cap. The cap has a portion with a relatively large diameter and multiple ribs for easy handling. The user holds the cap to install the lens cone on the laser system, and pulls the cap to unsnap it from the lens cone. The lens cone is attached to the laser system with a bayonet mount that provides tactile feedback to the user.
