Nat G. Adkins Jr. of Richmond, Texas recently received U.S. Patent 8,202,853 for “Convenience Kit For Eyelid Treatment."

Texas Business Patent of the Day:  A Fort Bend County man has devised a way to keep your eyelids clean.

Nat G. Adkins Jr. of Richmond, Texas recently received U.S. Patent 8,202,853 for “Convenience Kit For Eyelid Treatment."

Adkins applied for the patent more than three years ago on December 30, 2008. 

The patent assignee is OCuSoft Inc. of Rosenberg, Texas.

Adkins’ invention is related to a kit for treating ophthalmic or ocular disorders, according to the patent documents. More particularly, the present invention is a kit for treating eyelid infections and maintaining eyelid hygiene. 

The eyelids are important for ocular health because they protect the eyes from from airborne contaminants, such as pollen, dust particles or other foreign bodies. The eyelids contain several glands including the lacrimal glands and the specialized form of the sebaceous glands, the meibomian glands which produce layers of tear film that are critical for healthy eyes.

It is, therefore, important to ensure that the eyelids are free of parasitical infection and clean, that is, without oil, debris, desquamated skin, bacteria, or mites that may cause infection. 

A number of so-called eye infections, including dry, scratchy and irritated eyes, are caused by infected eyelids. Blepharitis is an inflammatory condition affecting the eyelids. This causes itching, burning and irritation of the eyelids. While blepharitis can be difficult to manage, following a regular eyelid hygiene routine can assist in removing the excess bacteria and toxic byproducts, including those found in cosmetics, thereby leading to a decrease in inflammation.

It is also important to ensure that the meibomian glands are unclogged. The meibomian glands are located at the eyelid margins, and are responsible for the production of sebum, an oil necessary for the formation of the outer layer of the protective tear film. Clogged meibomian glands impair tear formation which in turn leads to dry eyes and other resulting eye infections, including styes, chalazions, and posterior blepharitis or meibomian gland dysfunction. 

Several factors are involved in diagnosing and treating dry eyes, including tear production, quality of the tear film, lid hygiene, and even diet. The present invention offers convenient combination therapy for improving overall eyelid hygiene and also providing for adjunctive eyelid therapy. The kit of the invention comprises a tetracycline antibiotic, an eyelid cleansing composition, an anti-bacterial eyelid preparation and an eyewear apparatus. The various embodiments of the kit of the invention facilitate both treatment of infected eyelids and proper cleansing of the eyelids to prevent recurring infections and to increase tear film stability. 

In one embodiment, the tetracycline antibiotic is selected from a group consisting of doxycycline, minocycline, tetracycline, oxytetracycline, chlortetracycline, demeclocycline or pharmaceutically acceptable derivatives thereof. In one aspect of the invention, the tetracycline antibiotic is preferably doxycycline. Doxycycline is used to treat a variety of microbial infections, including acne, infections of the skin and the eyelids. Doxycycline works by preventing the growth and spread of bacteria and by inhibiting collagenase and reducing inflammation. In one embodiment of the invention, doxycycline is preferably administered as its hyclate salt or as a hydrate, preferably monohydrate. Doxycycline hyclate is administered by oral ingestion, preferably in tablet or capsule form or as an oral suspension 

In one embodiment of the eyelid treatment kit, each doxycycline tablet comprises a low dosage, from about 15 mg to about 50 mg of doxycycline hyclate. In other aspects of the invention, the kit comprises one or more light resistant containers for the doxycycline hyclate tablets. 

In one embodiment, the eyelid cleansing composition comprises a non-irritating formulation suitable for daily eyelid hygiene therapy, the non-irritating eyelid cleansing composition comprises a surfactant mixture comprising PEG-80 sorbitan laurate, sodium trideceth sulfate. PEG-150 distearate, disodium lauroamphodiacetate, cocamidopropyl hydroxysultaine, sodium laureth-13 carboxylate, sodium chloride, PEG-15 cocopolyamine, quaternium-15 and deionized water. 

In one embodiment, the anti-bacterial eyelid preparation comprises polyhexamethylene biguanide, 1,2-hexanediol, 1,2-octanediol and a pH stabilizing surfactant solution present in an amount effective to control the pH level of the composition between 5.5 and 7.5. 

Both the non-irritating eyelid cleansing composition and the anti-bacterial eyelid preparation can be formulated as an aqueous emulsion, a suspension, a dispersion, a foam, a cream, a lotion, a solution, a paste, a gel or a spray. In one aspect of the invention, the kit comprises one or more containers comprising either the non-irritating eyelid cleansing composition or the anti-bacterial eyelid preparation in solution form. The kit further comprises one or more applicators for applying the solution. The applicators comprise eyelid pads, disposable swabs or cotton balls. In another embodiment, the kit comprises a suitable pump dispenser for dispensing as foam either the non-irritating eyelid cleansing composition or the anti-bacterial eyelid preparation. In yet another embodiment, the kit comprises one or more pads pre-moistened with either the non-irritating eyelid cleansing composition or the anti-bacterial eyelid preparation. The pre-moistened pads can be conveniently applied to eyelids to be treated or cleansed and discarded after use. The pre-moistened pads are individually sealed and enclosed within impervious containers or packages. 

In one aspect of the invention, the pads comprise an inner and outer layer. A heating element is enclosed between the inner and outer layer. The heating element generates heat by a method of heat generation selected from an exothermic chemical reaction, conductive heat transfer from an enclosed heating pouch, molecular excitation via a microwave energy source, or a combination thereof. The heat from the heated pads opens up clogged and infected meibomian glands, thereby reducing eyelid infections. 

In another embodiment, the kit of the invention comprises an eyewear apparatus for treating dry eye conditions. In one aspect, eyewear apparatus comprises at least one pair of moist heat goggles, the moist heat goggles further comprising means to create heat and increase humidity around the eye to stimulate tear production and reduce the evaporation of natural tears. The moist heat goggles are specially designed to deliver moist heat directly to the orifice of the meibomian glands in order to loosen the sebum and increase the flow of healthy lipids to create a stable tear film. In another aspect of the invention, the kit comprises one or more moisture chamber goggles or glasses. Moisture chamber goggles are specially designed to retain moisture for patients suffering from dry eyes by forming a moisture chamber around the eyes. 

In another embodiment, the eyelid treatment kit comprises one or more instruction sheets. The instruction sheets contain doxycycline hyclate administration and dosage information. Additionally, the instruction sheets contain information on improving eyelid hygiene and treatment using the other components of the kit.
