10 . A method of manually using the patient interface device assembly of claim 9 to couple the patient's eye to the ophthalmic surgical laser system, comprising:

receiving the lens cone and the cap in the supplied configuration, wherein the lens cone is partially embedded inside the cap;

installing the lens cone on the ophthalmic laser system, including:

holding the cap with the lens cone embedded therein, inserting the plurality of protruding pins of the ophthalmic surgical laser system into the plurality of bayonet mount slots of the lens cone, and twisting the cap to slide the bayonet mount slots relative to the pins, thereby attaching the lens cone to the ophthalmic surgical laser system; and

pulling the cap to unsnap the cap from the lens cone; and

coupling the suction ring to the patient's eye via the flexible skirt.

11 . The method of claim 10 , wherein the lens cone and the suction ring are separate pieces, the method further comprising:

joining the lens cone and the suction ring to each other by inserting a portion of the lens cone into a receiving opening of the suction ring.

12 . A cap for use with a lens cone of a patient interface device for coupling a patient's eye to an ophthalmic surgical laser system, wherein the lens cone has a frustoconical shaped shell configured to be coupled to the ophthalmic surgical laser system, the cap comprising:

a cylindrical shaped upper portion;

a cylindrical shaped lower portion, having an outer diameter larger than an outer diameter of the upper portion; and

a plurality of longitudinal ribs formed on an exterior surface of the lower portion and distributed along its circumference;

wherein the lens cone is partially embedded inside the cap, and

wherein the shell of the lens cone includes a plurality of first snap features on its exterior, and the cap includes a plurality of second snap features on its interior, wherein the first snap features and the second snap features engage with each other to attach the lens cone and the cap to each other, and wherein the first snap features and the second snap features are configured to disengage from each other in response to a separation force to separate the lens cone and the cap.

13 . The cap of claim 12 , further comprising a circular step feature in an interior of the cap,
