Abstract: A light delivery system according to an example of the present disclosure includes a solar tracker that has a rectangular aperture that delivers light to a quadrant detector, a light collector configured to capture light from an incoherent light source, the captured light being sunlight, a delivery optics unit for delivering the captured light to a target object, and an optical fiber unit optically connects an output of the light collector to the delivery optics unit. A method of performing a surgical procedure, including an iridectomy procedure, is also disclosed.

Abstract: A trolley for supporting equipment on an overhead door using the existing track for the overhead door is described. The invention may be used to allow utility items such as lighting, electrical outlets, and safety devices to be mounted conveniently and efficiently.

Abstract: The invention provides an ophthalmic illuminator, including a battery, an electrical resistor, an electrical switch and an LED. The battery is in circuit with the battery; and the electrical switch is in circuit with the resistor, where electrical energy flows through the circuit when the switch is in the closed position. The light emitting diode is in circuit with the switch and generates blue light energy which in turn causes fluorescence in a fluorescien dye administered to the patient's eye when the switch is in the closed position. An optical element (e.g, a lens or reflector) can be disposed between the diode and the eye to increase blue light energy reaching the eye. The energy can be “pulsed” such that the diode generates the blue light at a predetermined frequency. A user of the illuminator, e.g., a physician, can hold the system by hand to operate the switch (e.g., through a button). A magnifier coupled to the system provides a magnified image of the patient's eye, if desired.

Abstract: A hand-held slit lamp instrument has a substantially elongated handle that houses one or more batteries and that connects to a line filament lamp. A front knob is threaded to the handle so that it is rotatable about the elongated axis of the handle. The front knob has an internal hollow section that houses one or more imaging elements to generate a slit image of the line filament out through an aperture in the front knob and away from the instrument. The rotation of the front knob axially displaces the imaging elements relative to the lamp to control the magnification and distance of the slit image. A rear knob also threads to the handle and rotates about the axis to provide an electrical switch. The rotation of the rear knob displaces the rear knob relative to the handle and between a first "ON" position and a second "OFF" position. A retaining ring, e.g.
