POST-OPERATIVE CATARACT KIT AND METHOD
A kit for use post-operatively by patients who have undergone cataract surgery and are unable to gather the medications and eyewear required for recovery, comprising a container for antibiotic and anti-inflammatory medications, special eyeglasses, an eye shield, and instructions for use of the contained products.
This application claims priority of U.S. Provisional Patent Application 61/509,942 filed Jul. 20, 2011, the contents of which are incorporated herein by reference.
FIELD OF THE INVENTIONThe present invention relates to systems and methods for providing post-operative treatment and, more particularly, to such systems and methods for providing continued treatment alter cataract surgery.
BACKGROUND OF THE INVENTIONAfter cataract and other eye surgeries, antibiotics need to be administered every few hours for several days. In addition, other medications such as anti-inflammatory drugs also need to be administered frequently. The drugs are typically delivered to the ocular surface and the front of the eye in the form of eye drops. Currently, almost all cataract surgery is performed as outpatient or ambulatory surgery leaving the follow-up administration of anti-infective and anti-inflammatory medications to the patient or other in-home care giver.
While the patient invariably receives at least one prescription to fill for their drugs, they oftentimes require additional post-operative aids or devices to improve their recovery. For example, doctors will frequently provide sunglasses to combat light sensitivity and an eye shield to wear while sleeping. The various elements of post-operative cataract care are therefore known, but they have never been offered together in a comprehensive convenience kit.
Particularly, doctors usually do not fill prescription medication orders in-house. The prescriptions are filled through a pharmacy. The doctor is often relied upon to provide the protective hardware e.g., sunglasses and shields), but a doctor's office or surgical center has a. primary purpose of treating the patient and not necessarily supplying their patients with post-operative aids. A pharmacy, while likely to have a selection of sunglasses and other post-operative aids, is primarily a drug dispensary and the needed post-surgery aids may not be provided.
Lastly, a typical post cataract surgery course of treatment includes three prescription medications. Sometimes one or more of these three individually prescribed medications is not available at the pharmacy, requiring the patient to fill that prescription at another pharmacy or to call the doctor to alter their prescription to an equivalent/available medicine.
Post-operatively, patients of cataract surgery have impaired vision for a day or so and are encouraged not to drive for at least that time. Unless they have a caregiver that can. collect the prescribed pharmaceuticals and the needed post-surgery aids, they may not receive the benefits of these products on a timely basis.
There is therefore a need for a convenient and reliable system and method to provide both the prescribed medications and all of the needed post-operative aids to a patient.
SUMMARY OF THE INVENTIONIn accordance with one form, of this invention there is provided an improved convenience kit having both prescribed eye medications and protective devices to improve a patient's overall treatment after cataract surgery. The present invention offers convenient combination therapy for improving overall post ocular surgery treatment and also providing protective hardware to reduce the likelihood of irritation or discomfort while the patient heals. The kit of the invention comprises a topical antibiotic, a topical non-steroidal anti-inflammatory medication, a topical steroidal anti-inflammatory medication, an eyewear apparatus, and an eye shield. In one non-limiting embodiment, the kit of the invention comprises only the topical non-steroidal anti-inflammatory medication along with an eyewear apparatus and an eye shield.
The various embodiments of the present invention facilitate the prophylactic administration of at least a non-steroidal anti-inflammatory medication while also providing the patient with approved protective devices in a single convenient it that can be prescribed under a single National Drug Code. In other preferred embodiments, both anti-infective and anti-inflammatory medications are provided with the approved protective devices in a single kit, while still prescribed under a single National Drug Code,
In one embodiment, the kit may be ordered from a pharmacy through a direct link or portal between the pharmacy and prescribing doctor's office. The portal is preferably a pre-established computer communications network between the prescribing doctor and pharmacy wherein the doctor submits an electronic prescription for the kit of the invention to a desired pharmacy. The pharmacy receiving the prescription for the kit of the invention then fills the prescription for the patient. Having the entire kit of the invention under a single National Drug Code helps to ensure that all of the components (both medicative and appliances) are provided to a patient when the pharmacy fills the prescription.
In another embodiment, the antibiotic is a broad spectrum antibiotic. In the preferred embodiment, the antibiotic is selected from a group consisting of gatifloxacin, moxifloxacin, ciprofloxacin, ofloxacin, levofloxacin, besifloxacin or pharmaceutically acceptable equivalents or derivatives thereof. In one aspect of the invention, the antibiotic is preferably a topical eye drop.
In another embodiment, the non-steroidal anti-inflammatory medication (NSAID) is selected from a group consisting of ketorolac tromethamine, bromfenac, diclofenac, nepafenac or pharmaceutically acceptable equivalents or derivatives thereof. In one aspect of the invention, the NSAID is preferably a topical eye drop,
In another embodiment, the steroidal anti-inflammatory medication (corticosteroid) is selected from a group consisting of prednisolone acetate, difluprednate, loteprednol etabonate, fluorometholone, or pharmaceutically acceptable equivalents or derivatives thereof. In one aspect of the invention, the corticosteroid is preferably a topical eye drop.
In another embodiment, the kit of the invention comprises eyewear for shielding the patient's eyes from light in both the visible and nonvisible spectrums. In one aspect, the eyewear apparatus comprises at least one pair of sunglasses which are wearable over prescription eyeglasses
In another embodiment, the kit of the invention comprises a rigid eye shield to be worn by the patient while sleeping. The eye shield is applied with a medical grade tape protecting the patient's eye from inadvertent contact while sleeping. In one aspect, the eye shield comprises a transparent plastic shield which allows the patient to see with the covered eye during the night. In another aspect, the eye shield comprises a flexible metal shield with a cushioned periphery.
In another embodiment, the kit of the invention comprises one or more instruction sheets. The instruction sheets contain anti-infective and anti-inflammatory administration and dosage information. Additionally, the instruction sheets contain information on treatment using the other components of the kit.
In another embodiment, the kit of the invention comprises a reclosable housing or bag, suitable for retaining all of the other components of the kit.
These and other objects, features and advantages of the present invention become apparent from the following description When viewed in accordance with the accompanying drawings.
Controlling the most common post-surgery complications related to cataract and other eye surgeries typically involves prophylactic administration of medications along with protecting the eye from further irritation. An example of such a complication is bacterial conjunctivitis. Ameliorating the inflammatory conditions related to these complications is typically achieved with several eye drops containing anti-infective and anti-inflammatory drugs.
Positive therapeutic effects have been achieved with patient/self-administered formulations of standard antibiotics, corticosteroids, and non-steroidal anti-inflammatory drugs following cataract surgery to prevent and treat post-operative inflammation and infection.
After surgery several problems associated with the eye, including inflammation and irritation, can be traced to bacterial infections (e.g., conjunctivitis). It is imperative for proper healing and future ocular health that the eyes are treated against post-surgery infections, It is also important to ensure that the patient physically protects their eyes during the healing process. The post-surgery cataract treatment kit 10 of the invention is adapted to provide for both the medicative therapy and physically shielding the eye from potential damage.
For convenience and before further description of the present invention, certain terms employed in the specification are collected here. These definitions should be read in light of the remainder of the disclosure and understood as by a person of skill in the art.
The phrase “effective amount” is an art-recognized term and refers to an amount of an agent that, when incorporated into a pharmaceutical composition of the present invention, produces some desired effect at a reasonable benefit/risk ratio applicable to any medical treatment. In certain embodiments, the term refers to that amount necessary or sufficient to eliminate, reduce or maintain (e.g., prevent the spread of) a symptom of ocular infection, or prevent or treat an ocular infection, such as conjunctivitis. The effective amount may vary depending on such factors as the disease or condition being treated, the particular composition being administered, or the severity of the disease or condition. One skilled in the art may empirically determine the effective amount of a particular agent without necessitating undue experimentation.
The term “treating” is an art-recognized term which refers to curing as well as ameliorating at least one symptom of any condition or disease.
The term “preventing,” when used in relation to a condition, such as conjunctivitis, is art recognized and refers to administration of a composition which reduces the frequency of, or delays the onset of, symptoms of a medical condition in a patient relative to an individual that does not receive the composition.
It should be readily appreciated by one skilled in the relevant arts that while three medications 12-16 are discussed in relation to kit 10, substantially any number of medically appropriate drugs may he included in various embodiments of the invention.
