A kind of ophthalmic lens with film coatingTechnical field
The present invention relates to ophthalmic lens technical field more particularly to a kind of ophthalmic lens with film coating.
Background technique
With the increase of age, the intraocular mineral crystal of human body will cause intraocular mineral crystal to become because of various factorsHarder, color is deeper and opaque.These factors include that the factors such as gene, ultraviolet light irradiation are intracorporal partly by natural crystallineCystine structure aoxidizes and is converted into Cystine structure, becomes harder and muddy, more than threescore old man so as to cause crystalIn there is about 10%~15% people to have cataract eye illness, if the mineral crystal of these people cannot by artificial lens replace will lose foreverEyesight is gone, thus, the sixties in last century ophthalmology medical science and technology worker begins trying the people for replacing muddiness with artificial lensEye lens restores the eyesight of cataract patient.
In existing ophthalmic lens, service life can be limited by material, at the same with the iris and imaging space in eyeballBetween the problem of having the transmitance of light, while the not natural eyeball of ophthalmic lens can equally filter a large amount of harmful lightLine, while long-term light intensity variation will affect the connection between entire lens and muscle and the nerve of eyeball.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of ophthalmic lens with film coating.
A kind of ophthalmic lens with film coating proposed by the present invention, including crystal cavity, the two of the crystal cavitySide inner wall is provided with iris, and the inner wall of crystal cavity is provided with lens, the both ends outer wall of the lens close to the side of irisIt is provided with ciliary muscle, and the one end of ciliary muscle far from lens is connected with the inner wall of crystal cavity, the outer wall of the lens is setIt being equipped with high-transparent film, and high-transparent film includes anterior capsule and Lens capsular, the outer wall of the anterior capsule is provided with neuroinduction piece, andThe side outer wall of neuroinduction piece is fitted on the inner wall of iris, and the outer wall of the Lens capsular is provided with groove, and trench wallFilled with annular constrictions band, the contact position of the Lens capsular and lens is provided with sensitivity speck close to four sides of annular constrictions band.
Preferably, the lens include bionical elastomer and elastic cavity, and to be located at elastic cavity close for bionical elastomerThe side of iris.
Preferably, the both ends of the junction between the anterior capsule and lens are provided with connection capsule, and connect the interior of capsuleWall is provided with compression signal piece, and compression signal piece is connected with ciliary muscle.
Preferably, the bionical elastomer is mutually fitted with the extruding space of elastic cavity with the shrink space of annular constrictions bandMatch, and the stretching travel of ciliary muscle and the crush stroke of lens are adapted.
Preferably, the lens are made of hydrophilic polyacrylic ester copolymer, and anterior capsule and Lens capsular are by hydrophobicityPolyacrylate copolymer is made.
The utility model has the advantages that lens are made of hydrophilic polyacrylic ester copolymer in the present invention, and anterior capsule and Lens capsular byHydrophobic polyacrylate copolymer is made, and can be matched by penetrating into different absorbents in implanted in soft crystalline materialIt closes, hydrophobic polyacrylate material, glass transition temperature is lower than 25 degrees Celsius, and morphotropism is greater than 80%, and refractive index is highIn 1.46, closer to natural lens, while being divided into anterior capsule and Lens capsular, and cooperate epineural sensing chip and extrudingMessage slot can effectively reduce the direct extruding between lens and muscle and the nerve of eyeball, extend the service life.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, completeSite preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1-3, a kind of ophthalmic lens with film coating, including crystal cavity 1, in the two sides of crystal cavity 1Wall is provided with iris 2, and the inner wall of crystal cavity 1 is provided with lens 5 close to the side of iris 2, and the both ends outer wall of lens 5 is all provided withIt is equipped with ciliary muscle 4, and the one end of ciliary muscle 4 far from lens 5 is connected with the inner wall of crystal cavity 1, the outer wall of lens 5 is provided withHigh-transparent film 3, and high-transparent film 3 includes anterior capsule 6 and Lens capsular 11, the outer wall of anterior capsule 6 is provided with neuroinduction piece 8, andThe side outer wall of neuroinduction piece 8 is fitted on the inner wall of iris 2, and the outer wall of Lens capsular 11 is provided with groove, and trench wallFilled with annular constrictions band 10, the contact position of Lens capsular 11 and lens 5 is provided with photosensitive close to four sides of annular constrictions band 10Point 12, lens 5 include bionical elastomer 7 and elastic cavity, and bionical elastomer 7 is located at elastic cavity close to the side of iris 2,The both ends of junction between anterior capsule 6 and lens 5 are provided with connection capsule, and the inner wall for connecting capsule is provided with compression signal piece9, compression signal piece 9 is connected with ciliary muscle 4, the extruding space and annular constrictions band 10 of bionical elastomer 7 and elastic cavityShrink space is adapted, and the stretching travel of ciliary muscle 4 and the crush stroke of lens 5 are adapted, and lens 5 are by hydrophilic polypropyleneAcid ester copolymer is made, and anterior capsule 6 and Lens capsular 11 are made of hydrophobic polyacrylate copolymer.
This ophthalmic lens, in implantation into eyeball, light enters iris 2, and the neuroinduction piece 8 in high-transparent film 3 can matchClosing compression signal piece 9 stimulates lens 5 and ciliary muscle 4, and lens 5 is made to be deformed into light-transmission angles, by anterior capsule 6 and after capsuleThe filtering noxious light of film 11.On sensitivity speck 12, it is imaged in eyeball.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and itsInventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
