Abstract
Medical devices and methods of use are disclosed to exam an eye of a patient. A medical device may include a digital projector as part of an illumination system. A medical device may include one or more cameras as part of an observation system to capture reflected light from the eye. The observation system may include one or more adjustable optical systems. The digital projector may produce a slit of light to be projected onto the eye. The slit of light and the observation system may be focused at a plurality of focal depths within the eye.
Claims30
A medical device for imaging at least a portion of an eye of a patient, the medical device comprising:
- a patient support adapted to position the eye of the patient;
- a movable base moveable relative to the patient support;
- an illumination system including at least one source producing light to illuminate the eye and an illumination system support arm supporting the at least one source, the illumination system support arm being supported by the moveable base and rotatable relative to the moveable base, the illumination system including a first adjustable optical assembly;
- an observation system including a first camera configured to receive imaging rays produced by reflection of light from the eye of the patient, and an observation system support arm supporting the first camera, the observation system support arm being supported by the moveable base and rotatable relative to the moveable base and rotatable relative to the illumination system support arm, the observation system including a second adjustable optical assembly having an optical axis, the observation system imaging at least one plane which is normal to the optical axis of the second adjustable optical assembly;
- and
- a controller operatively coupled to the first adjustable optical assembly of the illumination system and to the second adjustable optical system of 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 patient support;
- and
- adjust a rotational position of the illumination system support arm relative to the observation system support arm.

- a movable base movable relative to the patient support;
- an illumination system including at least one source producing light to illuminate the eye and an illumination system support arm supporting the at least one source, the illumination system support arm being supported by the movable base and rotatable relative to the movable base, the illumination system including a first adjustable optical assembly;
- an observation system including a first camera configured to receive imaging rays produced by reflection of light from the eye of the patient, and an observation system support arm supporting the first camera, the observation system support arm being supported by the movable base and rotatable relative to the movable base and rotatable relative to the illumination system support arm, the observation system including a second adjustable optical assembly, wherein at least one of the first adjustable optical assembly of the illumination system and the second adjustable optical assembly of the observation system includes a tunable lens;
- and
- a controller operatively coupled to the first adjustable optical assembly of the illumination system and to the second adjustable optical system of 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 patient support;
- and
- adjust a rotational position of the illumination system support arm relative to the observation system support arm.
