Further, in the above-described embodiment and its modification, the drug supply assisting tool 10 is directly attached to the eyeball, but the present invention is not limited to this, and the drug supply assisting tool 10 is attached via one or more media (for example, a member). It can also be indirectly attached to the eyeball.

Further, in the above-described embodiment and its modification, the drug supply assisting tool 10 is made of the same material as the soft contact lens, but is not limited to this, and is made of the same material or other material as the hard contact lens. You can also. For example, it can be configured as a drug 40 or other eye wear.

Further, in the above-described embodiment and its modification, the drug supply assisting tool 10 is formed in a circular shape as a whole in a planar shape, but the present invention is not limited to this, and any shape can be adopted. For example, if it is formed into a vertically elongated elliptical shape as a whole, it is easy to supply the drug to the deep part of the conjunctiva. Further, if the shape is formed in a horizontally long elliptical shape as a whole, the possibility or degree of interference with the palpebral conjunctiva can be reduced during symptoms such as conjunctivitis. In addition, any size can be adopted for the overall size of the drug supply assisting tool 10.

Further, in the modified example of the above embodiment (FIGS. 4, 6, 7, and 8), the through hole 12 is formed as a hole for opening the corneal region, but the present invention is not limited to this, and any number and any number can be used. It can be formed at any place with any size and any shape. For example, the through hole 12 can be formed as a hole that opens at least the pupil region (the region located in the pupil 22 at the time of wearing), or can be opened in the surface direction of the drug supply assisting tool 10. Further, since the amount of movement of the eyeball is larger in the left-right direction than in the up-down direction, the width (horizontal length) of the through hole 12 is determined from the viewpoint of reducing the possibility or degree of interference with the cornea 24. A configuration that is larger than the height (length in the vertical direction) of the through hole 12 can be adopted. From the same point of view, since the amount of vertical movement of the eyeball is larger in the upward direction than in the downward direction, the length from the reference point located at the center of the cornea 24 facing the front when worn in the through hole 12 to the upper end. Can be configured to be larger than the length from the reference point to the lower end. Considering these two points, the through hole 12 has, for example, a horizontally elongated elliptical shape in which the upper portion expands (the width is larger than the height, and the length from the reference point to the upper end is larger than the length to the lower end). Can be adopted. In this case, when the drug supply assisting tool 10 rotates on the surface of the eyeball due to the movement of the eyelid or the eyeball, the relative position of the through hole 12 with respect to the cornea 24 changes, so that the drug supply assisting tool 10 may rotate. Or, from the viewpoint of reducing the degree, for example, the drug supply assisting tool so that the upper edge of the drug supply assisting tool 10 is located (contacting or close to) the upper palpebral conjunctival fornix and the lower edge is located at the palpebral conjunctival fornix. A configuration that sets the size of 10 can be adopted.

Further, in the modified example of the above embodiment (FIGS. 4, 6, 7, and 8), the through hole 12 is formed as a through hole, but the present invention is not limited to this, and the through hole 12 can also be formed as a recess. This is because when the component of the drug 40 permeates the drug supply assisting tool 10 by diffusion or the like, it does not necessarily have to penetrate. Further, it is not necessary to provide the through hole 12 itself.

Further, in the above-described embodiment and its modification, the material of the drug supply assisting tool 10 has not been described, but it can be made of a soluble material. Thereby, the drug supply assisting tool 10 can be dissolved together with the drug 40. In this case, a material having a slower dissolution rate than that of the drug 40 can be used as the material of the drug supply assisting tool 10.

Further, in the modified example of the above-described embodiment, the drug 40 is adopted as an eye-wearing object to be attached to the drug supply assisting tool 10, but the present invention is not limited to this, as long as it is an eye-wearing object that can be worn on the eye. Any eye wear can be used. Examples of eye-wearing materials include (1) electronic devices, (2) soft contact lenses, hard contact lenses and other lenses, optical fibers, optical waveguides, optical isolators, optical devices such as semiconductor lasers, and (3) drug supply assistance.

Other sensors), (3) devices that provide information to the outside of the eye (eg, displays), (4) devices that collect information about the outside of the eye (eg, cameras, biosensors and other sensors), (5) A device that maintains, restores, imparts, or acts on the eye (for example, a medical device, a light emitting element, a piezoelectric element, a vibrating element, a heat generating element), or (6) imparts a function to the outside of the eye. A device (for example, a medical device, a light emitting element, a piezoelectric element, a vibrating element, a heat generating element) that performs an action can be adopted. Further, when an optical device or other eye device is adopted instead of the electronic device, the device having the above-mentioned functions (1) to (6) can be similarly adopted. Further, when the eye-wearing object is a hard contact lens, it is difficult for the hard contact lens to come into direct contact with the eyeball, so that the wearing feeling can be improved.

Further, in the above-described embodiment and its modification, the drug supply assisting tool 10 is adopted as an eye device, but the present invention is not limited to this, and any eye device that can be worn on the eye is used. can do. Examples of ophthalmic instruments include (1) electronic devices, (2) soft contact lenses, hard contact lenses and other lenses, optical fibers, optical waveguides, optical isolators, optical devices such as semiconductor lasers, and (3) drug supply aids. , (4) Corrective devices, or (5) Other eye devices can be adopted. Further, as the drug supply assisting tool 10, in addition to these (1) to (5), an eye-worn object that can be worn on the eye can be adopted. As the eye-wearing material, for example, in addition to these (1) to (5), (6) drug, (7) supplement, (8) ferrofluid, or (9) other eye-wearing material should be adopted. Can be done.
