Patient interface device for laser eye surgery having light guiding structure for illuminating eye

A system, comprising:

• a laser surgery apparatus, comprising:
• a laser source,
• a lens assembly configured to direct laser light from the laser source to a target area of a patient's eye for laser surgery,
• a docking receptacle, and
• an illuminating light source;
• and
• a patient interface device, comprising:
• a shell defining a chamber within,
• a first interface port configured to be interfaced with the patient's eye, the first interface port being disposed at a first side of the shell and including an applanating lens for application to the patient's eye during a laser surgery procedure,
• a second interface port disposed at a second side of the shell and configured to be interfaced with the docking receptacle, wherein air may be evacuated from the chamber by the laser surgery apparatus via the second interface port, and
• a light guiding structure having at a first end thereof a light receiving interface, configured to receive light from the illuminating light source, and having at a second end thereof a light-emitting interface, wherein the light-emitting interface is disposed adjacent the applanating lens and configured to provide the light in a vicinity of the patient's eye when the applanating lens is applied to the patient's eye.
