    摘要: This invention relates to copolymers and hydrogels formed by copolymerization of a hydrophilic monomer from the group of dihydroxyalkyl acrylates and methacrylates and a substantially water insoluble monomer from the group of alkyl acrylates and methacrylates. The preferred copolymer of the invention is formed from methyl methacrylate and glyceryl methacrylate (2,3-dihydroxypropyl methacrylate). The hydrogels of the invention have unique physical and physiological properties which are particularly useful for the formation of contact lenses, particularly contact lenses having a relatively thin cross-section, though they may also be used for other purposes such as drug and pesticides delivery devices, dialysis, ultrafiltratiaon and reverse osmosis membranes, implants in surgery and dentistry and the like.

    摘要: In one embodiment, an apparatus for treating mammalian meibomian glands involves clearing the meibomian glands. The apparatus comprises a heater configured to apply a regulated heat to an eyelid containing the meibomian glands to a temperature adequate to melt obstructions in the meibomian glands to put the obstructions in a fluid or suspension (melted) state, and a controller maintaining the heat for a time period adequate to melt the obstructions. The glands can then be mechanically treated by a mechanical treatment applicator to express fluid from the glands by using a compressive force, wherein the treating is carried out either during the time period or after the time period but while the obstruction remains in a fluid state. Subsequent pharmacological treatment of the glands by use a pharmacological agent (topical or systemic) can then be used to assist in maintaining proper flow of lipids from the glands. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

    摘要: This invention relates to an emulsion composition for the formation of an artificial tear film over the ocular surface of the eye capable of providing mechanical lubrication for the ocular surface while reducing evaporation of fluid therefrom. The emulsion is desirably in the form of a meta stable emulsion and is characterized by the use of a surfactant comprising a combination of a primary and secondary surfactant where the primary surfactant permits formation of the emulsion and the secondary surfactant permits autoclaving of the surfactant. The invention also includes a method for the formation of such an emulsion.

    摘要: A system for treating meibomian gland dysfunction comprising a heating element that applies heat to the tissue proximate the patient's meibomian glands to provide conductive heat transfer to the meibomian glands, which assists in the expression of obstructions or occlusions in the meibomian glands to restore sufficient sebum flow to the lipid layer to treat dry eye. A force application device may also apply force to tissue proximate the patient's meibomian glands during the application of heat to improve conductive heat transfer and reduce blood flow in tissue that causes convective heat loss, and to help express obstructions from the meibomian gland, including from a channel of the meibomian gland, with reduced discomfort to the patient. Reaching increased temperature levels may improve the melting, loosening, or softening of obstructions or occlusions in the meibomian glands.

    摘要: Methods of diagnosing meibomian gland dysfunction are disclosed. The methods may be standardized and provide an accurate diagnosis of whether meibomian gland dysfunction exists. In one embodiment, a method is provided that utilizes an evaluation tool to apply a force for a preselected period of time to at least one of a plurality of meibomian glands in two or more regions of a plurality of regions of an eyelid. A grade is assigned to the at least one meibomian gland of the plurality of meibomian glands in each of the two or more regions based on any secretion that is expressed from each meibomian gland. In this manner, a plurality of meibomian gland secretion grades is obtained. The plurality of meibomian gland secretion grades is indicative of the presence of meibomian gland dysfunction.

    摘要: A system for treating meibomian gland dysfunction. A controller controls heat applied to the tissue proximate the patient's meibomian glands to provide conductive heat transfer to the meibomian glands. The application of heat assists in the expression of obstructions or occlusions in the meibomian glands to restore sufficient sebum flow to the lipid layer to treat dry eye. A force is also applied to tissue proximate the patient's meibomian glands during the application of heat to improve conductive heat transfer and reduce blood flow in tissue that causes convective heat loss. Thus, the application of force can further increase the temperature level and/or reduce the time to reach desired temperature levels for removing obstructions. Reaching increased temperature levels may improve the melting, loosening, or softening of obstructions or occlusions in the meibomian glands. Reducing the amount of time to reached desired temperature levels an aid in reducing discomfort to the patient during treatment.
