Attorney Docket No. 105676-432984EYELID ADHESIVE PATCH AND METHOD FOR EYELID CLOSURECROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional Application No.63 / 730,352, filed December 10, 2024, the contents of which are hereby incorporated by reference.BACKGROUND
[0002] Lagophthalmos, characterized by incomplete closure of one or both eyelids, is a common problem that impacts many people. It occurs in normal individuals and hospitalized patients who have been medically sedated and / or paralyzed (e.g., in the intensive care unit and operating room). Studies indicate that lagophthalmos has an incidence of 42% in the ICU population, over 50% in the asymptomatic general population, and 79% in the symptomatic dry eye patient population.
[0003] Lagophthalmos desiccates the cornea - the clear tissue in front of the eye’s pigmented iris - by exposing it to air. Abnormal drying-out of the cornea is a condition called exposure keratopathy (EK) and is further subdivided into short- and long-term subtypes. Short-term EK is associated with pain and foreign body sensation in the eye upon waking, excessive eye watering, and redness of the eye, but some individuals may be asymptomatic despite substantial corneal damage. Vision and comfort may be negatively impacted during the early hours of the day but progressively improve before recurring the next morning. Long-term exposure causes vision-threatening problems due to the breakdown of the cornea’s protective outermost layer, the corneal epithelium. Long-term EK can result in corneal abrasions, infections, scars, and even emergent corneal perforations. Left untreated, long-term EK can lead to permanent vision loss and can even require a corneal transplant.
[0004] Short-term EK is commonly seen as an exacerbating factor in patients with obstructive sleep apnea (OSA) who wear continuous positive airway pressure (CPAP) devices when they sleep. In these patients, air leakage from the CPAP mask can blow toward the eyes. Air leakage combined with lagophthalmos results in short-term EK, with many CPAP wearers waking in the morning with pain, foreign body sensation, redness, tearing, and irritation. There are various treatments to mitigate lagophthalmos in CPAPAttorney Docket No. 105676-432984wearers, including goggles, masks, and tape. Goggles and masks represent a significant burden to the user because of their size and high profile above the face, adding to the already burdensome size of many CPAP masks. Tape can be ineffective at keeping the eyelids fully closed and represent an impediment to nighttime waking (e.g., in individuals with urinary frequency) because the tape must be removed and re-stuck. Tape is also difficult to apply to one’s own eyes. Gels and ointments blur the vision.
[0005] Short-term EK is also commonly seen as an exacerbating factor in patients with Dry Eye Disease. Lagophthalmos aggravates underlying ocular surface inflammatory symptoms (i.e., pain, redness, foreign-body sensation) and increases the likelihood of corneal damage (i.e., scarring). There are various treatments to mitigate lagophthalmos in dry eye patients; however, methods such as tapes can be ineffective at keeping the eyelids fully closed at night and incompatible with nighttime waking (e.g., in individuals with urinary frequency). Gels and ointments blur the vision; goggles are uncomfortable; and, like tape, all the above fail to provide adequate relief.
[0006] Long-term EK is common in hospitalized patients who are sedated and / or paralyzed for one day or longer and whose eyecare is dependent on healthcare providers. Despite being 100% preventable, EK affects 21-56% of ICU patients. It is not standard in all hospitals to have an EK prevention protocol and in its absence, nurses understandably prioritize life-sustaining care over eye care. Where preventive measures are employed, tape or occlusive dressings are commonly used, which are even more inadequate in the inpatient setting than they are at home. Such dressings are also problematic because of the ICU’s protocol for pupil monitoring at least once per nursing shift, which requires repeated removal of adhesives that can damage the delicate eyelid skin and even cause corneal abrasions if improperly placed. Ophthalmic ointments, which are nearly ubiquitous in ICU protocols, make adhesive reapplication ineffective.
[0007] EK poses risks beyond the ICU setting. Lengthy surgeries under general anesthesia, especially where the patient lies prone (i.e., spine procedures) significantly increase the risk of short- and long-term EK. The incidence of corneal epithelial damage after surgery under general anesthesia is 10%. Other less common medical scenarios may put a patient at risk for EK. Lagophthalmos occurs in patients with a previous blepharoplasty, the most common invasive cosmetic facial surgery; thyroid eye disease, aAttorney Docket No. 105676-432984rare condition that affects 10 per 100,000 people; and facial palsy, stroke-associated facial paralysis that affects as many as 40,000 per year.
[0008] The widespread prevalence of lagophthalmos and EK across diverse disease states underscores the urgent need for effective and comfortable solutions. Innovations addressing complete eyelid closure in both ambulatory and inpatient settings are essential to safeguarding ocular health and mitigating the risks associated with these conditions.
[0009] Those skilled in the art label the area of the eyelid that is on the side of the nose as medial in location; the area of the eyelid that is on the side of the ear is labeled lateral in location. Mild lagophthalmos is associated with the medial area of the eyelids incompletely closing, but more severe lagophthalmos is associated with both the medial and lateral areas of the eyelids incompletely closing. Mild exposure keratopathy is more common than severe exposure keratopathy. Thus, the medial area of the eyelids is the most common location of incomplete eyelid closure and the medial area of the ocular surface is more common than the lateral surface to exhibit exposure keratopathy.
[0010] The surface geometry of the closed eyelid area is complex. It includes multiple regions with differing curvatures: the concave medial canthal region adjacent to the nasal bridge characterized by tight, multidirectional radii; the convex palpebral surface characterized by a larger radius of curvature; and the convex superior, inferior, and lateral orbital rim regions that transition continuously from the palpebral surface onto the facial bones. Together, these regions define a contiguous anatomical surface.
[0011] The eyelid area is covered by the thinnest skin on the human body, which is fragile and highly sensitive to traction and chemical irritation. It includes the medial and lateral canthi, eyelid margins, eyelashes, and eyebrow. The skin is prone to irritation from adhesives, which may cause contact dermatitis, and is susceptible to mechanical injury during adhesive removal. The hair is also prone to undesired epilation during adhesive removal.
[0012] Hydrogel adhesives have several properties that make them well-suited for application to the eyelid area. They can be high tack and highly compliant, allowing them to conform and adhere to the complex surface geometry of eyelid skin. At the same time, they can be gentle and removed atraumatically with minimal discomfort. Hydrogels can also be inert and therefore unlikely to cause irritation or noxious skin reactions. InAttorney Docket No. 105676-432984addition, they can be formulated to incorporate bioactive agents that provide physiological benefits during use. Adhesive hydrogels can be in high water content. Those skilled in the art express hydrogel water content as a percentage of the gel’s mass. High water content makes the adhesive hydrogel feel cool to the touch when applied to the skin. Wearers can perceive the coolness of the adhesive hydrogel as soothing. High water content also makes the adhesive hydrogel conductive to temperature. The tackiness of adhesive hydrogels can be measured by 90-degree peel tests after the adhesive has been adhered to stainless steel or bakelite plastic; tackiness can also be measured with PSTC-5, ASTM, or D6862 standard test methods. The gentleness of peeling adhesive hydrogels after it has been stuck to a surface can be measured by elongation of the gel at release, expressed in a percent value of the baseline thickness.
[0013] Those skilled in the art define hypoallergenic as less likely to cause irritation or allergic reaction. Those skilled in the art define translucency as visual difference of distinct images on each side of a material as measured by Contrast Ratio or Transparency Parameter. Those skilled in the art define transparency as the ability for light to pass through a material without appreciable scattering. Those skilled in the art define opacity as the inability of light to pass through a material. Those skilled in the art define Tack as the quick stickiness of a material which can be measured by methods such as the Rolling Ball Tack Test described in ASTM D3121 or indirectly as the 90* peel strength as described in ASTM D6862-11. Those skilled in the art define Pliability as the ease with which something bends without breaking, comparable to drapability and flexural stiffness as described in ISO 9073-9:2008(E), ASTM D1388-23, ASTM F3260-25. Those skilled in the art define Traumatically as causing injury to tissue and atraumatically as not causing injury to tissue.SUMMARY
[0014] An eyelid adhesive patch described below addresses the challenges of lagophthalmos and exposure keratopathy with a one-piece eyelid adhesive patch. In a one-piece eyelid adhesive patch, multiple adhesive layers adhere to different types of skin. In a two-piece eyelid adhesive patch, the two pieces are fastened together by some means, e.g., hook and loop, adhesives, a button, etc. The eyelid adhesive patch provides a means for the eye to be opened and closed without removing the adhesive completely.Attorney Docket No. 105676-432984The sensitive skin adhesive layers provide skin adhesion to the delicate skin of the eyelids, while the higher-tack adhesive layer adheres to less sensitive skin, such as the cheek skin.
[0015] The adhesive strength of the eyelid adhesive is tunable, allowing for multiple pieces to be designed with gentler adhesives for short-term closure (e g., in overnight use at home) that prioritize patient comfort and minimize skin irritation. In other embodiments, the eyelid adhesive would prioritize durability, lasting longer than an average ICU admission of 3-4 days.
[0016] For individuals with Dry Eye Disease and OSA who wear CPAP, the eyelid adhesive patch provides a means for easy eye opening during nocturnal hours without the need for adhesive removal. In the ICU, it provides a means for eye examinations and ointment administration without removing the adhesive.
[0017] In another embodiment, a one-piece eyelid adhesive patch may comprise a two- stage eyelid closure mechanism for use in operating rooms, which caters to patients who do not require repeated eyelid opening as well as nurse-anesthetists, who need to know that the eyelids are 100% closed every case.
[0018] An external eyelid adhesive patch must conform to the anatomical boundaries of the eyelid region to avoid patient discomfort and irritation. A single supporting member is positioned on the eyelid area with its medial boundary located medial to the medial canthus and generally ending before the nasal bridge. Its lateral boundary is located lateral to the medial canthus and generally ends before the lateral orbital rim. Its inferior boundary is located below the inferior eyelid margin and generally ends before the inferior orbital rim. Its superior boundary is located above the superior eyelid margin and generally ends before the superior orbital rim. Locating the member within these boundaries supports reliable adhesion and comfort during eyelid closure.BRIEF DESCRIPTION OF THE DRAWINGS

[0065] Those skilled in the art will be familiar with key terms used to describe hydrogel adhesive properties. Water content refers to the proportion of the adhesive composed of water, which influences how cooling it feels to the touch. Tack describes the adhesive’s ability to stick to the skin upon light contact. Elongation reflects the stretchability of the material as it is peeled from the skin; higher elongation reduces shear forces on the skin and supports gentle removal. Hypoallergenic refers to the adhesive’s inert characteristics, indicating that it is unlikely to elicit irritation or other adverse reactions.
[0066] Those skilled in the art will recognize that certain hydrogel adhesives exhibit both high compliance and high tack, which can make them difficult to handle without sticking to themselves. Such adhesives benefit from being bonded to a non-adhesive backing substrate, which provides shape stability while maintaining contour-conforming drapeability. The combination of the backing substrate and the skin-facing hydrogel adhesive is commonly referred to as an integral web. Backing materials can be selected for their degree of shape stability, stretchability, and contour-conforming pliability. They can also be chosen for their optical properties, including translucency or opacity, and for their ability to retain a plurality of microcapsules containing aromatic substances.Attorney Docket No. 105676-432984Additionally, backing substrates can be selected for their hypoallergenic properties, thickness, and tactile feel.
[0067] Those skilled in the art will recognize that the complex surface geometries of the eyelid area — particularly the concave medial canthal region adjacent to the nasal bridge, characterized by tight, multidirectional radii, and the convex superior, inferior, and lateral orbital rim regions — require an optimal combination of a hydrogel adhesive and a backing substrate. The hydrogel adhesive must provide sufficient tack to adhere effectively to these curved and irregular surfaces, as hydrogels with insufficient tack tend to spontaneously release from areas of complex curvature. The backing substrate must balance pliability and shape stability: substrates that are insufficiently pliable can pull the hydrogel off convex and concave surfaces, while substrates that lack adequate shape stability cannot exert a closure force sufficient to oppose the eyelid’s natural opening force. Together, a hydrogel adhesive with adequate tack and a backing substrate with appropriate pliability and shape stability enable durable adhesion and reliable eyelid closure.
[0068] Those skilled in the art will recognize that laminating a backing substrate and a hydrogel adhesive into an integral web comprising multiple layers is a process known as conversion. High-volume conversion of an eyelid adhesive patch can be accomplished using a roller system, which bonds the hydrogel adhesive to the backing substrate and cuts the final perimeter shape with a roller die cutter, although other methods may also be employed. Roller systems require that material relationships within the same layer run parallel to the direction of movement through the system. Accordingly, a linear separation between two areas of an adhesive layer must run parallel to the rolling direction, with one area positioned to the left of the separation and the other to the right. Similarly, two distinct adhesives within the same layer must be arranged relative to each other in a left-right orientation. A grabbable non-adhesive portion of the backing substrate is likewise positioned to the left or right of the adhesive within the same layer. These left-to-right relationships enable highly efficient roller die cutting without requiring precise registration of the cut relative to a specific position on the moving material.Attorney Docket No. 105676-432984
[0069] Those skilled in the art will recognize that an eyelid adhesive patch can be configured to transdermally deliver physiologically beneficial bioactive agents to eyelid tissues, including the skin, eyelashes, and meibomian glands. Such bioactive agents may include, for example, vitamins, retinoids, polysaccharides, peptides, growth factors, antioxidants, anti-inflammatory substances, botanical extracts, salts, acids, silicones, ceramides, metal ions, liposomes, nanoemulsions, nanoparticles, hydration-boosting agents, antibiotics, corticosteroids, calcineurin inhibitors, or combinations thereof.
[0070] Those skilled in the art will recognize that an eyelid adhesive patch can be configured to transmit olfactory stimuli to the wearer. This functionality can be achieved by including a layer containing a plurality of microcapsules with aromatic substances, such as essential oils, fragrance compounds, or combinations thereof.
[0071] Those skilled in the art will recognize that an eyelid adhesive patch can be configured to reduce light perception through the closed eyelid. Such a feature can be particularly beneficial in situations where ambient light is bright, such as during air travel, while the wearer desires to sleep.
[0072] The present disclosure is directed towards an eyelid adhesive patch. Those skilled in the art will recognize that the eyelid adhesive device could serve as an adhesive eyelid patch, an eyelid closure support device, an adhesive eyelid closure support device, an eyelid closure device, and / or similar terms.
[0073] In one aspect, the present disclosure is directed to an eyelid adhesive patch. FIGS 1A-1G illustrate a first embodiment of an eyelid adhesive patch 10.
