1. A medical device for imaging at least a portion of an eye of a patient, the medical device comprising:
an illumination system including a digital projector producing at least one image to illuminate the eye and a first adjustable optical assembly to project the at least one image towards the eye;
an observation system including a second adjustable optical assembly positioned to receive imaging rays produced by reflection of light from the eye of the patient due to the projection of the at least one image towards the eye by the illumination system and a first camera configured receive the imaging rays from the second adjustable optical assembly, the illumination system and the observation system being positioned in a first spatial configuration with an optical axis of the first adjustable optical assembly and an optical axis of the second optical assembly intersecting at an apex of a cornea of the eye; and
a controller operatively coupled to the illumination system and to the observation system, the controller configured to adjust the first adjustable optical assembly of the illumination system and the second adjustable optical system of the observation system to a plurality of focal depths relative to the eye while the illumination system and observation system are in the first spatial configuration.
