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.
Claims20
A medical device for imaging at least a portion of an eye of a patient, the medical device comprising:
- an illumination system configured to project a test pattern on the eye of the patient;
- a first camera positioned to capture a first image of a first portion of a reflection of the test pattern from the eye along a first direction;
- a second camera positioned to capture a second image of a second portion of the reflection of the test pattern from the eye along a second direction;
- and
- a display to configured to display at the same time at least a first display portion of the test pattern based on the first image and a second display portion of the test pattern based on the second image to provide an indication of an alignment state of the first camera and the second camera relative to the eye of the patient.
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 relative to the eye;
- and
- a controller operatively coupled to the illumination system and to the observation system, the controller configured to align the illumination system and the observation system to the eye and 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 eye while the illumination system and observation system are in the first spatial configuration.
