Abstract: A single-piece patient interface device for coupling a patient's eye to an ophthalmic surgical laser system includes a cone substrate with a rigid frustoconical shaped shell for coupling to the laser system, and a flexible suction ring integrally joined to the lower end of the rigid shell for coupling to the patient's eye. The suction ring has a circular skirt extending downwardly from a base portion, a diaphragm extending from the base portion and disposed inside of the skirt, and a contact lens held by the diaphragm to cover a center opening. When the skirt contacts the eye's surface, the skirt, the diaphragm, the contact lens and the eye surface form a vacuum chamber, where a vacuum may be applied to secure the patient interface device to the eye. The parameters of the suction ring are optimized to fit a large range of eye sizes, including smaller eyes.

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 either joined together by clamping or formed integrally as one piece. 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.

Abstract: A method used in a corneal lenticule procedure for finding the visual axis location before eye docking, to track the visual axis location displacement during docking, and to center the lenticule incision pattern at the visual axis location after docking, without ink-marking the visual axis location at the center of the cornea with ink or other substance. Two docking illumination beams are illuminated on the eye surface at oblique angles, and a first eye image is taken before docking while the eye looks at the fixation light of the laser system. A second eye image is taken after docking. The pre-docking cornea apex position is obtained based on the two reflected light spots of the docking illumination light. Pupil center is obtained in both images. The post-docking corneal apex is then calculated from the pre-docking cornea apex position and the pre- and post-docking pupil center positions.
