摘要:
The invention provides an in vivo screening assay and an in vitro screening assay for rapid screening of diabetes. A method of the invention includes determining a first glucose concentration in an ocular fluid of a patient; administering orally a load of carbohydrate to the patient; determining a second glucose concentration in an ocular fluid of the patient at a period of time of less than 50 minutes after orally administering of the load of carbohydrate; comparing the second glucose concentration with the first glucose concentration to determine if the patient is likely to be a diabetic. The method of the invention is performed by using a kit of the invention. The kit comprises: (1) a glucose-sensing ophthalmic device and instructions for using the glucose-sensing ophthalmic device to screen for diabetes; or (2) two or more tear-collecting devices, and a testing agent composition which specifically reacts with glucose to form a detectable signal. The glucose-sensing ophthalmic device comprises a testing agent composition which specifically and reversibly interacts with glucose to form a detectable optical signal which changes in a concentration-dependent manner.

The invention, in one aspect, provides a strip for tear collection. The strip has a first end and an opposite second end and preferably has substantially uniform cross-sections from the first end to the second end. The strip is made of a hydrogel material in substantially dry state. The strip is characterized by having a substantially uniform swelling along the hydrogel strip from the first end to the second end when fully wicked by a tear fluid and by having a correlation between the volume of tear uptake by said strip and the length of the wicked end portion of said strip. A strip of the invention is useful for assay of an analyte of interest in a tear fluid. The invention also provides a method and kits for assaying an analyte of interest (e.g., lactoferrin, glucose, herpes simplex virus, hormones, etc.).

The present invention provides a lens care kit for disinfecting and cleaning contact lenses. The lens care kit of the invention comprises a colored lens care solution including a colored protein and a proteolytic enzyme. The kit of the invention allows customers to visually identify when their lenses are disinfected, clean, and ready to wear. The invention relies upon a color change to indicate the completion of disinfection and cleaning of contact lenses.

The present invention provides a lens care kit for disinfecting and cleaning contact lenses. The lens care kit of the invention allows customers to visually identify when their lenses are disinfected, clean, and ready to wear. The invention is relied on color change, due to temporally photo-bleaching of a colored lens care solution, to indicate the readiness of disinfection and cleaning of contact lenses.
