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: Apparatus and method for interfacing an ophthalmic surgical laser system with a patient's eye using a single-piece patient interface (PI). The PI includes a hollow shell, with an applanation lens and a flexible skirt at its lower end. Through channels are formed around the applanation lens to connect the spaces above and below the lens. When the PI is coupled to the laser system and the eye, the upper rim of the shell forms a seal with the laser system and the flexible skirt forms a seal with the eye. A vacuum is applied to the interior of the shell via a vacuum port on the laser system, and the vacuum is communicated to the space enclosed by the applanation lens, the skirt and the eye through the channels around the lens. A magnetic mechanism is also provided to hold the PI shell to the laser system.

Abstract: An imaging system for an ophthalmic laser system includes a prism cone made of a transparent optical material and disposed downstream of the focusing objective lens of the ophthalmic laser system, the prism cone having an upper surface, a lower surface parallel to the upper surface, a tapered side surface between the upper and lower surfaces, and a beveled surface formed at an upper edge of the prism cone and intersecting the upper surface and the side surface, and a camera disposed adjacent to the prism cone and facing the beveled surface. The camera is disposed to directly receive light that enters the lower surface of the prism cone and exits the beveled surface without having been reflected by any surface.

Abstract: A single-piece patient interface device (PI) for coupling an patient's eye to an ophthalmic surgical laser system, which includes a rigid shell, a flexible suction ring joined to a lower edge of the shell, an applanation lens, and a flexible annular diaphragm which joins the applanation lens to the shell near the lower edge of the shell. The flexible diaphragm allows the applanation lens to move relative to the shell, including to shift in longitudinal and lateral directions of the shell and to tilt. In operation, the surgeon first secures the PI to the patient's eye by hand, and then couples the laser system to the PI by lowering the laser delivery head into the PI shell. During the lowering process, the laser delivery head presses the applanation lens down relative to the PI to applanate the cornea of the eye.
