Claims27
An apparatus for illuminating and viewing the anterior segment of an eye of a patient comprising:
- a binocular microscope having an optical axis;
- an electronic sensor;
- an electronic display coupled to display an image captured by the electronic sensor;
- a slit lamp utilizing a light emitting diode (LED) configured as a source of light to illuminate the anterior segment of an eye of a patient when forming an image of the anterior segment of an eye of a patient;
- and
- a beam directing element configured to transmit a first part of light returned from the anterior segment of an eye of a patient along the optical axis of the binocular microscope and to direct a second part of light returned from the anterior segment of an eye of a patient to the electronic sensor to allow viewing of the image on the electronic display and visual observation through the binocular microscope of the anterior segment of an eye of a patient.

- transmitting a first part of light returned from the anterior segment of an eye of a patient along the optical axis of a binocular microscope to allow visual observation of the anterior segment of an eye of a patient;
- directing a second part of light returned from the anterior segment of an eye of a patient toward an electronic sensor to allow digital imaging of the anterior segment of an eye of a patient;
- displaying an image of the anterior segment of an eye of a patient captured by the electronic sensor on an electronic display to allow viewing of the image on the electronic display;
- and
- pulsing the LED in synchronism with trigger pulses used to trigger the electronic sensor.
