Abstract
The present invention provides a kind of artificial lens of modified form, the multiple contacts being in contact including optics area and with pouch, optics area has preceding surface and rear surface, wherein rear marginal surface has the Zhou Bianqu of a right angle boss, the boss can stop proliferation of lens epithelial cells to surface after crystal.Wherein it is connected between the preceding surface in optics area and support button loop in an excessive form in obtuse angle, because artificial lens has certain viscosity, is coordinating injector in use, when can avoid folding in artificial lens, optics area is connected with each other with support button loop.Present invention increase support button loop planar dimension, can improve mechanical property, make artificial lens more stable in pouch, reduce the overall thickness of artificial lens, artificial lens is more suitable for small otch injector.
Description
Technical field
The invention belongs to medical domain, and in particular to a kind of that there is raising pouch stability to reduce behind post gelating time edge
Room artificial lens.
Background technology
Artificial lens is used it is well known that intraocular lens refers to a kind of special lenses that synthetic material is made
Become muddy mineral crystal because of cataract in substitution, with medical treatment development, soft artificial intraocular lens more and more replace
Rigid artificial lens, wherein soft artificial intraocular lens have hydrophilic, hydrophobic point, and soft artificial intraocular lens are generally also referred to as foldable artificial
Crystal, coordinate after folding injector be implanted to one it is less cut it is aerial, can be with Automatic-expanding after implantation pouch.
On current international market, with Ai Erkang（Xian Shu Novartis）, refined this two major company of person of outstanding talent be main hydrophobic artificial lens master
Want manufacturer, using Rui Na, Baushe ＆ Lomb as the company represented be the main manufacturer of hydrophilic artificial lens.
Postcataract posterior capsular opacification is the common complication of Lens implantation latter, and posterior capsular opacification is due to lens epithelial
Cell propagation has arrived what surface and rear capsule after crystal were thereby resulted in.
Cataract operation, crystal needs to be used cooperatively with injector, and otch used by injector is generally 2-3mm, plants
Enter rear crystal Automatic-expanding.
The content of the invention
Goal of the invention：The present invention is a kind of artificial lens, and the purpose is to prevent proliferation of lens epithelial cells to arrive after the implantation
Surface and rear capsule after crystal, so as to solve the complication of postcataract posterior capsular opacification present in prior art.
Technical scheme：
With the back room artificial lens for improving pouch stability reduction post gelating time edge, it is characterised in that：Including optics area；Institute
State optics area side and be provided with two support buttons loop；
Described two support buttons loop are bent in the opposite direction respectively；
The optics area includes preceding surface and rear surface, and the support button loop has oblique angle transition contact face in preceding surface side；
The rear marginal surface carries the Zhou Bianqu of right angle boss, surface of the right angle boss higher than support button loop.
Having described in above-mentioned technical proposal improves the back room artificial lens that pouch stability reduces post gelating time edge, excellent
Selection of land：The right angle boss is higher than 0.2 millimeter of the surface of support button loop being connected with rear surface.
Having described in above-mentioned technical proposal improves the back room artificial lens that pouch stability reduces post gelating time edge, excellent
Selection of land：From root, the transition through contact surface is progressively increased the thickness of the support button loop, and thickness increases direction towards forward face.
Having described in above-mentioned technical proposal improves the back room artificial lens that pouch stability reduces post gelating time edge, excellent
Selection of land：The width of the support button loop narrows using root to be most wide to end is progressive.
Having described in above-mentioned technical proposal improves the back room artificial lens that pouch stability reduces post gelating time edge, excellent
Selection of land：Support button loop on the basis of optics district center circumference symmetry arrangement, between angle be 180 °.

The advantage and effect that the present invention possesses be：
To pass through boss stop proliferation of lens epithelial cells to surface after crystal, it is to avoid postcataract posterior capsular opacification it is concurrent
Disease；
It is connected between the preceding surface in optics area and support button loop in an excessive form in obtuse angle, because artificial lens has certain viscous
Degree, is coordinating injector in use, when can avoid folding in artificial lens, optics area is connected with each other with support button loop；
Increase support button loop planar dimension, can improve mechanical property, make artificial lens more stable in pouch；
The overall thickness of artificial lens is reduced, artificial lens is more suitable for small otch injector；
Embodiment：
The present invention is a kind of artificial lens, including optics area and multiple contacts for being in contact with pouch, and optics area has preceding surface
With rear surface, wherein rear marginal surface has the Zhou Bianqu of a right angle boss, the boss can stop proliferation of lens epithelial cells
Surface after to crystal, it is to avoid the complication of postcataract posterior capsular opacification.
Concrete structure and technical characteristic of the present invention are as follows：
As shown in the figure：Artificial lens 1 of the present invention, including optics area 2 and support button loop 3a, 3b are integral type, described two support buttons loop
3a, 3b are bent in the opposite direction respectively；The effect in optics area 2 is to converge to light on retina, and 2 points of optics area is preceding surface
5a and rear surface 5b, support button loop 3a, 3b effect is then to be implanted into after pouch stable effect of playing.
In preceding surface 5a sides, support button loop 3a, 3b respectively have an oblique angle form excessively to form new contact on support button loop
Face 3a1,3b1（Such as Fig. 6）, the purpose of this structure is to make the artificial lens of product thinner, is easy to use cooperatively with injector.It is described
From root, the transition through contact surface 3a1,3b1 is progressively increased support button loop 3a, 3b thickness, and thickness increases direction towards forward face
5a。
There is a right angle boss 6 at 5b edges in surface afterwards, and boss height supports fasten with a rope, string, etc. 3a, 3b than what is be connected with rear surface 5b
Surface is high 0.2 millimeter（Such as Fig. 7）, the boss can stop proliferation of lens epithelial cells to surface after artificial lens.
Described support button loop 3a, 3b width narrow using root to be most wide to end is progressive；Support button loop 3a, 3b are with optics
Circumference symmetry arrangement on the basis of the center of area 2, between angle be 180 °.Mechanical property can be improved, make artificial lens in pouch more
It is stable.
