  • Patent number: 10252078
    Abstract: Provided herein are ophthalmic phototherapy devices and associated phototherapy methods for promoting healing of damaged or diseased eye tissue. An ophthalmic phototherapy device includes a light emitting mechanism for transmitting light of at least one preselected wavelength to the eye tissue. An ophthalmic phototherapy method includes directing light of at least one wavelength for a selected period of time to a portion of damaged or diseased eye tissue, whereby the light transmitted to the damaged or diseased eye tissue stimulates cellular activity in the eye tissue to promote healing.

  • Patent number: 5060062
    Abstract: A visual sensory aid system for the partially sighted, designed to be worn around the eyes in a manner similar to that of eyeglasses. Light incident to the image source is detected by receptors mounted on the front lens and processed by the electronic circuitry. The resulting signals, representative of the image, are transmitted to monitor areas on an interior lens that extends from beyond the periphery of one eye to beyond the periphery of the other. The right and left images displayed on the monitor areas are reversed at a high frequency in order to simulate a visual stereo effect for depth perception. Areas of the monitors corresponding to blind spots of the eye are electronically inactivated. A feedback system maintains the focal point of the eye in the optimum direction.

  • Patent number: 4414974
    Abstract: A disposable, or one-time-use microsurgical knife has a slidable shroud that can be moved into a forward position to protect the blade, and can be moved rearwardly to allow use of the knife. The shroud, as well as other parts of the knife, are made of plastic, and a phosphorescent material is included to render the knife luminescent during steps taken in a darkened operating room. The extremely sharp razor chip blade includes a shank selectively wedged into the knife body so blades are interchangeable.
