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.
Claims11
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 moveable base moveable relative to the patient support;
- an illumination system including a digital projector producing at least one image to illuminate the eye and an illumination system support arm, 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;
- and
- a controller operatively coupled to the first adjustable optical assembly of the illumination system and to the second adjustable optical assembly of the observation system, the controller configured to
- adjust the first adjustable optical assembly of the illumination system and the second adjustable optical assembly of the observation system to a plurality of focal depths relative to the patient support while the moveable base remains stationary relative to the patient support, wherein a first subset of the plurality of focal depths are part of a first contour and a second subset of the plurality of focal depths are part of a second contour, the second contour being offset relative to the first contour, and wherein the digital projector produces a first image having a first vertical slit for a first focal depth of the first subset of the plurality of focal depths and a first focal depth of the second subset of the plurality of focal depths and the digital projector produces a second image having a second vertical slit, offset relative to a location of the first vertical slit in the first image, for a second focal depth of the first subset of the plurality of focal depths and a second focal depth of second subset of the plurality of focal depths.
