1. A system to facilitate alignment of an eye with a patient interface of a laser device, comprising:
a camera configured to record a plurality of images of the eye through the patient interface of the laser device;
a display screen configured to display the images of the eye; and
a computer configured to facilitate alignment of the eye with the patient interface by:
identifying an outline in an image received from the camera, the outline based on contact with the patient interface by a liquid on an outer surface of the eye;
generate an alignment overlay that indicates a desired outline that aligns the eye with the patient interface;
place the alignment overlay onto the image; and
instruct the display screen to display the image with the alignment overlay.
