Abstract
The invention relates to an artificial iris with color change capability. The artificial iris comprises an artificial iris diaphragm and a photochromic shading layer, wherein the artificial iris diaphragm has a transparent disc structure, the center of which is provided with a hole, and pores are distributed on the artificial iris diaphragm; the photochromic shading layer is arranged in the artificial iris diaphragm, and the photochromic shading layer has a concentric ring structure; when the shading layer is irradiated by light, the photochromic substance in the shading layer changes color to reduce the transparency; and the thickness of the photochromic shading layer is distributed in a mode that the center is thin and the edge is thick, so that the photochromic capability (namely shading capability) of the shading layer is gradually enhanced together with the increment of the distance to the center. The artificial iris can be used for treating human eyes of eye traumas or pathological iridocoloboma, plays a role of a natural iris, and can regulate the pupil and the light transmission amount according to the illumination in the surrounding environment. The artificial iris with a fastening wire for fixing also solves the problem of high operation difficulty because the conventional artificial iris needs to be sutured at the eye.
Description
Technical field
The present invention relates to a kind of artificial iris, specifically, relate to the artificial iris that a kind of usefulness has metachrosis.
Background technology
Pathological changes or wound may cause the atrophy of iris disappearance, and the control luminous energy power of eye and the effect of restriction aberration are disappeared, and visual function is in low state for a long time.Because the iris of atrophy disappearance can't make it regeneration by means such as medicines at present, so need to use the mode of operation to repair.Modus operandi commonly used has iris suture and artificial iris to implant.Iris suture is an elasticity of utilizing remaining normal iris tissue, with the iris tissue sutured together, plays the effect of certain control light and restriction aberration.Artificial iris is to utilize artificial material instead of part or whole iris.
The iris of human body self can change the size of iris central authorities pupil according to the illuminance generation muscular movement of surrounding owing to be subjected to neural control.And present artificial material can't realize adjusting according to illuminance the function of pupil or logical light quantity.
In addition, existing artificial iris normally is fixed on the remaining iris with suture way or in iris root or the ciliary groove.This mode needs to carry out the complicated suture and the operation of knotting in the space of narrow within the eye and sealing, and the difficulty of operation is big, has limited carrying out of this kind operation.Make the patient of numerous coloboma of iris can not get effective treatment.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of artificial iris, and its inside comprises photochromic light shield layer, makes artificial iris adjust pupil and logical light quantity according to the illuminance in the surrounding.
For solving the problems of the technologies described above, artificial iris of the present invention comprise artificial iris every with photochromic light shield layer, wherein:
Described artificial iris is divided into central foraminous transparent disc shape structure, and artificial iris every on also be distributed with aperture;
Comprise photochromic light shield layer at described artificial iris every inside, photochromic light shield layer is the donut structure, but printed iris pattern, when being subjected to rayed, photochromic material in the light shield layer is understood variable color and is reduced transparency, the thickness of described photochromic light shield layer is the mode profile that central authorities are thin, the edge is thick, wherein the thickness near medium pore is 0.1-0.2mm, submarginal thickness is 0.2-0.3mm, thereby makes the photochromic function (being light shielding ability) of light shield layer increase and strengthen gradually with the distance at distance center;
Preferably, described artificial iris every outer circumference diameter be 8-12mm, gross thickness is 0.2-0.6mm, the aperture of medium pore is 3-5mm.
The current of buying a house in installments that act as of described aperture lead to, and preferred, the number of aperture is 1-3, and diameter is 0.2-0.25mm.
Preferably, also further be distributed with the crack on described artificial iris, operating theater instruments is conveniently used in acting as of this crack.More preferably, the number in described crack is 1-3, and length is 1.5-2.5mm.
As a kind of improvement of the present invention, described artificial iris can further include fixing with the button loop silk, and described fixing number with the button loop silk is greater than 1 and for centrosymmetry distributes, and in the filament portion that fastens with a rope, string, etc. the part of expanding is arranged.By button loop silk artificial iris is being carried out ophthalmic fixedly the time, the silk of will fastening with a rope, string, etc. penetrates scleral walls, with the elasticity of button loop silk and the part of expanding artificial iris is fixed on the scleral walls, thereby has avoided suture to fix this class complicated operation operation, and can be firm be fixed on the scleral walls.
Preferably, the number of described button loop silk is 3 or 4, and length is 5-7mm, and thickness is 0.3-0.5mm, and width is 0.4-0.6mm, and the top of described button loop silk is anti-slip T shape, zigzag, barb-like structure.
Describedly expand acting as of part and be stuck in the sclerotic puncture mouth and sentence and reach the fixed purpose of ophthalmic, preferably, described number of expanding part is 1-3, when expanding the number of part during greater than 1, can select a place to expand part according to the size of eyeball and fix.
Preferably, above-mentioned photochromic material include but not limited to triarylmethane, stilbene (Stilbene), azepine Stilbene, nitrone, fulgide (fulgides), spiro-pyrans, aphthopyrans, spiral shell-oxazines, 1 ', 3 '-dihydro-1 ', 3 ', 3 '-trimethyl-6-nitro spiral shell [2H-1-.alpha.-5:6-benzopyran-2,2 '-(2H)-indole], 1,3-dihydro-1,3,3-trimethyl-spiral shell [2H-indole-2,3 '-[3H] luxuriant and rich with fragrance [9,10-b] (1,4) oxazine].
Preferably, above-mentioned artificial iris includes but not limited to silica gel, polyethylene, PMMA (polymethyl methacrylate), acrylate etc. every using the button loop silk by any identical or different biocompatible materials with fixing.
Preferably, above-mentioned artificial iris is every, light shield layer and fixing one-body molded by casting film with the button loop silk, thereby do not need polishing punching to wait reworking, clean, encapsulation, can be after sterilizing for clinical use.
Artificial iris of the present invention can be used for treating the human eye of ocular injury or pathologic coloboma of iris, play the effect of natural iris, because the thickness of photochromic light shield layer is the mode profile that central authorities are thin, the edge is thick among the present invention, under different illumination conditions, the iris center is different with the transmittancy of periphery, thereby make the photochromic function (being light shielding ability) of light shield layer increase and strengthen gradually with the distance at distance center, therefore, the artificial iris of the present invention can also be adjusted pupil and logical light quantity according to the illuminance in the surrounding.
When artificial iris of the present invention is implanted in operation, can be fixed on the remaining iris or in iris root or the ciliary groove by suture way.As what implant is to have fixing artificial iris with the button loop silk, then can carry out ophthalmic by the button loop silk fixes, earlier artificial iris is curled after implantation device is implanted the anterior chamber, after treating that it launches naturally, be directed to outside the sclera with the entry needle silk of will fastening with a rope, string, etc. through the sclerotic puncture mouth, because button loop wire material elastical retraction selects the suitable part of expanding to be stuck in sclerotic puncture mouth place according to the needs of eyeball size, prune unnecessary button loop silk back and bury fixingly in the sclera flaggy, it is fixing not need additionally to sunken cord.
