Description
Technical 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 factors
Harder, color is deeper and opaque.These factors include that the factors such as gene, ultraviolet light irradiation are intracorporal partly by natural crystalline
Cystine structure aoxidizes and is converted into Cystine structure, becomes harder and muddy, more than threescore old man so as to cause crystal
In 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 forever
Eyesight is gone, thus, the sixties in last century ophthalmology medical science and technology worker begins trying the people for replacing muddiness with artificial lens
Eye 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 eyeball
Between the problem of having the transmitance of light, while the not natural eyeball of ophthalmic lens can equally filter a large amount of harmful light
Line, 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 cavity
Side 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 iris
It 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 set
It 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, and
The 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 wall
Filled 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 elastomer
The 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 capsule
Wall 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 band
Match, 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 hydrophobicity
Polyacrylate 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 by
Hydrophobic polyacrylate copolymer is made, and can be matched by penetrating into different absorbents in implanted in soft crystalline material
It closes, hydrophobic polyacrylate material, glass transition temperature is lower than 25 degrees Celsius, and morphotropism is greater than 80%, and refractive index is high
In 1.46, closer to natural lens, while being divided into anterior capsule and Lens capsular, and cooperate epineural sensing chip and extruding
Message slot can effectively reduce the direct extruding between lens and muscle and the nerve of eyeball, extend the service life.
