The flexible folding artificial lens represented is expected more and more instead of other rigid artificial lens, using flexible material as generation
The artificial lens of table possesses that notch is small, reduces the advantage of patient suffering.
Hydrophilic artificial crystal material is poly- hydroxy ethyl methyl methyl acrylate, has mesh space structure, due to there is hydroxyl
Base has water imbibition, compared with hydrophobic artificial lens, is easily implanted into, and this kind of small notch of 1.8mm, 2.2mm can be used
Injector.
Typically, be connected position between hydrophily artificial lens body region and support button loop, and support button loop shape, relatively
Thiner, after being implanted into pouch with injector, the active force between support button loop and pouch is too low, easily causes crystal and sends out within the eye
Phenomena such as raw rotation, offset, inclination.
Postoperative posterior capsular opacification is the common complication of Lens implantation latter, and posterior capsular opacification is since Lens Epithelial Cells increase
It grows resulting to crystal rear surface and rear capsule.
After implantable artificial crystal, manually crystal positioning hook transposes to the artificial lens after implantation to doctor's needs,
Until position is transferred to most preferably.
Summary of the invention
Goal of the invention: the purpose of this utility model is that the design of improvement artificial lens support button loop, avoids due to mechanical property
Can be bad, artificial lens is due to unstable appearance after being implanted into pouch, phenomena such as rotating, deviate within the eye, tilting.
A kind of technical solution: modified form back room artificial lens, it is characterised in that: the artificial lens includes body region and branch
Support button loop；
The body region includes optics area and peripheral region；
For the front surface and rear surface in the optics area under same focal power, radius of curvature is identical；
The peripheral region is 0.2mm thicker than optics area edge；On the radial section of the artificial lens, body region and support
Right angle step is formed by peripheral region between button loop；
Shrinkage pool is provided on the support button loop.
The modified form back room artificial lens, it is characterised in that: the support button loop is two, is connect with peripheral region；Institute
Two support buttons loop are stated with optics district center circumference symmetry arrangement.
The modified form back room artificial lens, it is characterised in that: on radial section, support button loop and body region at 5 °~
10 ° of angles.
The modified form back room artificial lens, it is characterised in that: the shrinkage pool on support button loop is strip groove profile through-hole.
The modified form back room artificial lens, it is characterised in that: described two support button loop bending directions are opposite.

Advantage and effect:
The utility model improves the design of artificial lens support button loop, avoids since mechanical property is bad, in implantation pouch
Artificial lens is due to unstable appearance afterwards, phenomena such as rotating, deviate within the eye, tilting.
Design of the utility model due to strengthening support button loop, is improved mechanical property, while can reduce artificial
Size after crystal optics district center keeps the volume of hydrophilic artificial lens smaller, reduces the wind that patient swells after occurring after being implanted into
Danger.
The utility model support button loop on be provided with groove, artificial lens after the implantation by pouch pressure when, play slow
The effect of punching, while manually crystal positioning is hooked into capable positioning after artificial lens implantation convenient for doctor.
There is square edge design on two surfaces before and after intraocular lens optic area to the utility model simultaneously, can stop epithelial cell
Proliferation causes Posterior Capsular Opacification, while right angle side side is in be smoothly connected with optics area surface, is kept in intraocular lens optic area
Size after the heart.
The utility model in optical design using etc. biconvexs design, so that product is can achieve optimal imaging quality.
Specific embodiment:
As depicted in figs. 1 and 2, artificial lens 7, including body region 1 and support button loop 4a, 4b, are integral type by same material
It constitutes, wherein body region 1 is made of optics area 2 and peripheral region 3, and optics area is made of front surface 2a and rear surface 2b, peripheral region 3
Than 0.2mm behind the edge in optics area 2, to form a new right angle step Fig. 4 between support button loop 4 and optics area 2, this is straight
Angle step can effectively stop proliferation of lens epithelial cells to optics area 2.Shrinkage pool 6a, 6b on support button loop 4a, 4b, as power transmission
Supporting part, when artificial lens 7 is squeezed in pouch, support button loop 4a, 4b can rotate inward compression, play buffering and make
With will not influence optics area 2, guarantee stability of the hydrophilic artificial lens 7 in pouch with this.
Simultaneously in optical design, 2a, 2b in Fig. 2 are such using identical radius of curvature under same focal power
Design can make patient reach better visual experience, ensure that simultaneously, the consistency of artificial lens front and rear surfaces makes artificial crystalline substance
Body uniform force within the eye.
Square side design in Fig. 3 can make the thickness in the entire optics area of artificial lens become larger, and increase the whole body of artificial lens
Product, the risk swollen after increasing after implantation, Fig. 4 is the square side design after improvement, and on optical zone dimension without influence, square side is also simultaneously
It is connected to the effect that support button loop also functions to reinforcing rib with optics area.
Fig. 5, Fig. 6 are the another type of perspective view and left view of artificial lens, the structure and Fig. 1 and figure at each position
2 is consistent, including body region and support button loop, is made of for integral type same material, wherein body region is by optics area and peripheral region structure
At uniquely difference is that body region and support button loop have an angle, and angular range can be seen in Fig. 6 at 5 ° to 10 °.
