1. A patient interface device for coupling an eye of a patient to an ophthalmic surgical laser system, comprising:
a shell formed of a rigid material and defining an interior space, wherein the shell has an upper end defining an upper opening between the interior space and an exterior of the shell, and a lower end defining a lower opening between the interior space and the exterior of the shell, and is free of any other openings between the interior space and the exterior of the shell or any fluid conduit attached to the shell;
a transparent applanation lens mounted to the shell and disposed inside the shell adjacent to the lower opening;
a flexible seal affixed to and extending upwardly from the upper end of the shell, the flexible seal extending along an entire circumference of the upper opening of the shell and is configured to couple to the ophthalmic surgical laser system to form an air-tight seal between the ophthalmic surgical laser system and the patient interface around the upper opening; and
a flexible skirt affixed to and extending downwardly from the lower end of the shell, the flexible skirt extending along an entire circumference of the lower opening of the shell and is configured to couple to the eye of the patient to form an air-tight seal between the eye and the patient interface around the lower opening.
