    摘要: A method for measuring the relative thickness of the lipid layer component of the precorneal tear film on the surface of an eye. Light is directed to the lipid layer of a patient's eye with an illuminator that is a broad spectrum light source covering the visible region and is a lambertion light emitter such that the light source is specularly reflected from the lipid layer and undergoes constructive and destructive interference in the lipid layer. The specularly reflected light is collected and focused using a collector such that the interference patterns on the tear film lipid layer are observable. The collector also produces an output signal representative of the specularly reflected light which is suitable for further analysis.

    摘要: The disclosure comprises a method for measuring the relative thickness of the lipid layer component of the precorneal tear film on the surface of an eye after distribution of the lipid layer subsequent to blinking. Light is directed to the lipid layer of a patient's eye with an illuminator. The illuminator is a broad spectrum light source covering the visible region and is a lambertion light emitter such that the light source is specularly reflected from the lipid layer and undergoes constructive and destructive interference in the lipid layer. The specularly reflected light is collected and focused using a collector such that the interference patterns on the tear film lipid layer are observable. The collector also produces an output signal representative of the specularly reflected light suitable for further analysis, such as projection on to a high resolution video monitor or analysis by or storage in a computer.

    摘要: A method and composition for reducing evaporation of an aqueous layer from the surface of the eye. The method comprises applying a gel of oil and wax over the eye, preferably in the form of a meta-stable oil in water emulsion in a dosage not exceeding 100 microliters. The gel is formed by gelling a hydrocarbon oil with a wax, preferably dispersed in aqueous medium at a pH of at least about 8.0.
