Definitions

• the present invention relates generally to the field of medical devices and, more specifically, to a handheld device that stimulates the meibomian gland of the eyelid mechanically.
• Untreated meibomian gland disease can lead to ocular infection and/or inflammation of the eyelids (referred to as posterior blepharitis).
• Posterior blepharitis if untreated, can lead to corneal disease, which can lead to uncorrectable blurred vision and blindness, in severe cases.
• the middle layer comprising the bulk of the tear film, is the aqueous (water) layer, and the outermost layer, is a thin (less than 250 nm) layer (“lipid layer”) comprised of many lipids.
• lipid layer a thin (less than 250 nm) layer
• the typical upper eyelid has about 25 meibomian glands and the lower eyelid has about 20 meibomian glands.
• the meibomian gland orifices open onto the eyelid margin at and around the junction of the inner mucous membrane and the outer skin of the eyelids; that junction is termed the mucocutaneous junction.
• Dry eye disease is the result of a malfunction in the tear. Tears of the eye are made from different elements. The majority of the tear film is thin fluid that comes from the lacrimal gland, which is located directly above the eye. The quantity and quality of this fluid is usually not the problem.
• the meibomian glands which are located throughout both the upper and lower eyelids and number in the range of twenty per lid, secrete an oily material (lipids), that keeps the watery part of tears (i.e., the fluid secreted by the lacrimal gland) from evaporating. This material is normally
• the upward phase of blinking causes the upper eyelid to pull a sheet of the lipids secreted by the meibomian glands upward and over the other two layers of the tear film, thus forming a type of protective coating which limits the rate at which the underlying layers evaporate.
• a defective lipid layer or an incorrect quantity of such lipids can result in accelerated evaporation of the aqueous layer, which in turn, causes symptoms such as itchiness, burning, irritation, and dryness, which are collectively referred to as "dry eye”.
• dry eye When left untreated, the consequences of dry eye can be severe, and even result in loss of vision (e.g., from desiccation of the corneal epithelium, ulceration and perforation of the cornea, or an increased incidence of infectious disease).
• Dry eye states have many etiologies.
• a common cause of dry eye states is a disorder in which the glands are obstructed or occluded, usually referred to as
• Meibomian gland dysfunction is frequently the result of keratotic or biofilm obstructions which partially or completely block the meibomian gland orifices. Such obstructions compromise the secretory functions of the individual meibomian glands. More particularly, these obstructions can comprise combinations of bacteria, sebaceous ground substance, dead cells, and/or
• eyelid margin inflammation e.g., anterior and posterior blepharitis, hordeolum, sty, chalazion, and rosacea.
• eyelid margin inflammation e.g., anterior and posterior blepharitis, hordeolum, sty, chalazion, and rosacea.
• the etiological factors of many of these inflammations include an overgrowth of bacteria (and/or parasites) and their toxic waste. These bacteria not only cause the lipid tear film to dysfunction, but they also destroy and block the very lipid-producing infrastructure by attacking the glands in the eyelid skin.
• the particular types of bacteria and parasites that cause the inflammation/infections are common. The chance of having these on the eyelids is nearly 100%.
• the tear film operates as a singular entity and all of the layers are important
• the lipid layer which is secreted from the meibomian glands, is of particular significance as it functions to slow the evaporation of the underlying layers and to lubricate the eyelid during blinking; such slowing of evaporation and lubrication of the eyelid largely prevent "dry eye syndrome and/or Ocular Surface Disease".
• the meibomian glands of mammalian eyelids secrete oils that prevent evaporation of the tear film and provide lubrication to the eye and eyelids.
• These glands can become blocked or plugged by various mechanisms leading to so-called "dry eye syndrome and/or Ocular Surface Disease". While not the only cause, meibomian gland dysfunction is believed to contribute to or be the primary cause of approximately 86% of dry eye syndrome. Dry eye syndrome is characterized by a blockage of the meibomian glands, which prevents normal lipid secretions from flowing from the meibomian glands to form the lipid layer of the tear film.
• Eye drops such as REFRESH ®, SOOTHE®, and SYSTANE® brand eye drops are designed to closely replicate the naturally occurring healthy tear film.
• a third problem is that the prior art eyelid care devices with motorized handpieces use unidirectional rotary tools (aka "heads") that become entangled with hair.
• a fourth problem is that eyelid care devices with rotary tools cause many patients to flinch when the tool first contacts the eyelid margin. Such flinching increases the risk of contact by the tool with the cornea, sclera, or other parts of the eye and resulting in laceration or other injury.
• a fifth problem is a lack of instrumentation of prior art motorized eyelid care devices, for which instrumentation (e.g., proximity monitoring, cleaning efficacy) and features (e.g., safety shutoff) would enable safer use of an eyelid care device as well as data collection and analysis of clinical signs and efficacy of cleaning.
• the ability to massage the meibomian glands while the eye is closed is beneficial to a majority of patients that have difficulty controlling the eyelid to allow direct stimulation of the meibomian glands.
• an eyelid scrub typically contacts only the anterior ciliary margin and does not clean the entire confluence of the mucosal surface of the conjunctiva and the cutaneous epithelium. Even though daily eyelid hygiene is critically important for patients with an eyelid disease, there is typically no compliance by patients for whom SA Cleaning is ordered by their ophthalmologist. Due to a lack of alternatives, "baby shampoo" and a washcloth or cotton-tipped swab is often recommended by ophthalmologists for a patient's SA Cleaning.
• eyelid scrubs are available in several forms, such as impregnated, pre-moistened towelettes or pads, or as bottled cleansers applied to a non-sterile applicator pad or to fingertips, such eyelid scrubs do not improve patient compliance or efficacy of the treatment. These rely on the individual to perform vigorous back and forth scrubbing of all four eyelid margins, which is cumbersome, time consuming, sometimes painful, and has uneven results. These factors are all strong disincentives to following an eyelid cleaning regimen.

• At least one eyelid cleaning device uses a design and unidirectional rotation virtually identical to that of ophthalmic burrs, but with a "sponge head" instead of a burr.
• the BlephEx® device drives a head with a full rotary motion and is for use by eyecare professionals.
• An "eyecare professional” is a person skilled in the art of ocular hygiene, such as ophthalmologists, optometrists, nurses trained in eyecare, and technicians trained in eyecare.
• the BlephEx® handpiece rotates a small sponge, is guided along the eyelid margin by an eyecare professional, removes scurf and debris, and exfoliates the eyelids.
• the key disadvantages of the BlephEx® device are its "motorized swab" design, unidirectional spinning (rotating) head (as distinct from an oscillating head moving in a reciprocally arcuate path), lack of instrumentation, and lack of safety features. Using an oscillating head to clean eyelids has significant advantages over existing art eyelid cleaning devices.
• Oscillating devices tend to be safer than rotary devices; an oscillating head does not have the directional "kick" (i.e., start-up torque) of a rotating head, so there is less chance of a user losing control of the device, e.g., the device jumping out of the user's hand. For that reason, devices with oscillating heads are easier to control than rotary devices.
• An oscillating eyelid care device does not induce a flinch response in the subject when the head first contacts an eyelid.
• An oscillating head creates fewer flying debris than a rotary head, making an oscillating head a better choice for work in an area where excessive flying debris might be a nuisance, such as near the eye.
• the BlephEx® device can only safely be used by an eyecare professional due to the ergonomics and dynamics (e.g., "motorized swab” form, flinch induction, unidirectional rotation) of the device.

• One study (Preber H, Swed. Dent. J. 1991 ; 15:229-234) found that 75% of dental biofilm was removed in 15 seconds with an oscillating powered toothbrush; the same amount of plaque removal required twice as long with a manual brush. The results of a more thorough cleaning process with oscillating powered toothbrushes can be extrapolated to eyelid hygiene using an oscillating powered device.
• powered toothbrushes cannot be easily adapted to eyelid care, given the large size of the handpiece, brush head attachment, and brush head, the stiff bristles on toothbrush brush heads (which would lacerate the eyelid margin, cornea, and sclera if used to clean eyelid margins), and the expense of disposable "necks" (the “neck” is the detachable distal portion of a powered toothbrush that terminates in a non-removable brush head, which means the entire neck must be discarded when the brush head wears, rather than disposal of only the brush head). Because powered toothbrush necks are not easily removed and are used for months before replacement, the brush heads become unsanitary. For sanitary eyelid care, the head of a device must be easily replaceable and inexpensive, or durable and autoclavable.
