Edge design is processed as the wedge shape being inwardly recessed, and a kind of sharp bevel edge, after being similar to Greek alphabet Σ prevention from the side
While capsule muddiness, dazzle is prevented.
This field research reduces the risk of post gelating time also by crystalline lens material design is changed.Referring to " the third of Mandle
Olefin(e) acid intraocular lens' ratio PMMA, siloxanes IOL cause less post gelating time " ophthalmology news, the phase of volume 14 15, page 23
(1996).And " relationship between artificial lens biomaterial and posterior capsule opacification " (Relationship of Ursell et al.

It can selectively be destroyed crystalline in lens capsule in the fixed trypsase in lenticular surface when being implanted in lens capsule
Body epithelial cell prevents the generation of post gelating time.
Although suitable on these theoretical methods, it is secondary that the toxicity of drug itself will lead to serious complication, intraocular poison
Significant reaction, poor specificity or curative effect be not high, and there are drug excessive velocities, discharge unstable situation, cannot be guaranteed simultaneously
All people's work Lens Epithelial Cells in pouch are killed, there are certain difficulties for these Technical investment clinical applications, any remaining
LEC final hyperplasia and may be moved on intraocular lens after pharmacy effect disappearance, eventually lead to PCO.
In terms of Surgical technique, oculist understands that remaining crystal body cell causes post gelating time, therefore is performing the operation
In always strive to improve modus operandi reduces the residual of epithelial cell as far as possible, and its carefully remove it is all remnants crystalline lenses
Epithelial cell also develops the instrument of removal, such as: it is white that patent CN103099705A discloses a kind of prevention and treatment late coming
The device of cataract or glaucoma (PCO) can be optionally removed lens epithelial cells in operation, to prevent the generation of post gelating time.
However although having done many effort, generally also has a considerable amount of epithelial cells and stay on the inner surface of lens capsule, this is
Because epithelial cell is difficult to recognize and is often difficult to touch due to the limitation of their positions on the inner surface of lens capsule
And.
In recent years, photodynamic therapy or photo-thermal therapy also attract attention in the research of field of ophthalmology.Patent WO2013/
027222 reports the chlorophyll photosensitizer for treating disease of eye;Patent CN103083133 reports a kind of based on Jenner
The retinopathy photothermal laser treatment system of rice stick;Patent WO97/33619 reports a kind of photodynamic therapy by eye and changes
The method of kind eyesight;Patent WO98/25648 reports a kind of light sensitivity for being used to prepare eye disease optical dynamic therapy medicine
Close object;WO98/25610 reports a kind of for treating the green Porphyrin-Based Sensitizer drug of After Cataract;It is treating in white
United States Patent (USP) 5733276 discloses prophylactic laser retinopexy method in terms of barrier inverse position method.According to the method, go irradiation artificial with laser
Crystalline peplos, to destroy remaining lens epithelial cells;Patent CN100455276C coats two on intraocular lens surface
TiOx nano film inhibits lens epithelium by the inhibition and oxidation of titanium dioxide optical catalyst cell proliferation
Cell.
But traditional photodynamic therapy and photo-thermal therapy is all limited by photosensitizer and can not treat intraocular implants
Body post gelating time is widely used.Photosensitizer used in traditional photodynamic therapy and photo-thermal therapy, including light power type are photosensitive
Agent and photo-thermal type photosensitizer, finally require that liquid preparation is made, and enter lesion after entering blood by modes such as intravenous injections
Tissue or direct injection enter pathological tissues, and after treatment end, photosensitizer needs that body is discharged by the modes such as degrading or being metabolized
Outside.The problems such as safety and metabolism of traditional photodynamic therapy and photo-thermal therapy due to needing to consider photosensitizer, significantly
Limit the range and type of photosensitizer selection.Although the toxic side effect very little of photodynamic therapy, used photosensitizer
Human body is eventually entered into, there is certain toxicity.And photosensitizer can not generally be used alone, and need and other drugs or compound
Collective effect is entered in human body in the form of solution, outstanding mixed liquid or lotion, and the compound of these and photosensitizer interaction also will
With certain toxicity, increase Operative risk.In addition, since photosensitizer needs are internal from being injected intravenously, and require injection speed
Quickly, also quickly, the organ-tissues such as sick human heart and blood vessel need to bear photosensitizer over the course for the treatment of fast removing speed degree
It is uncomfortable brought by speed injection;And only when photosensitizer passes through pathological tissues, laser irradiation can be opened and carried out effectively
Treatment, therefore to delivery time and hold time and all propose higher requirement, bring difficulty for therapeutic process.
The prior art prevents the migration of epithelial cell by the design of intraocular lens, and then reaches prevention inverse position method
Purpose, effect are limited.It removes lens epithelial as far as possible in operative process, the generation of inverse position method can also be reduced
Rate, but actually it is difficult fully erased epithelium with physical method, these operations need the additional time, may will increase ocular tissue
Damage, causes the destruction of blood-aqueous barrier to increase, and damage have stimulated the proliferation of residual epithelium cell again;Though the IOL of sharp edges
So it is proved to be able to inhibit PCO, but there are still LEC along rear capsule and a possibility that in IOL surface migration, such case is especially held
Easily occur under the contact and the non-uniform situation of power between intraocular lens periphery and pouch, as intraocular lens exist after performing the operation
Moving in rotation in pouch;Drug and chemical method are removing or are destroying residual lens epithelial cells proliferation and migration is that have very much
Effect, but drug and chemical method the problem of there is drugs to other tissue toxic side effects, in the same of damaged epithelium
When, can also toxic damages be generated to its intraocular hetero-organization, this is still the failure to solve the problems, such as very well, in addition, there are also active drugs
The concentration duration is short, needs the problem of being administered continuously;Traditional photodynamic therapy and photo-thermal therapy is all by the limit of photosensitizer
It makes and can not be widely used in treatment intraocular lens' post gelating time.Laser Posterior capsulotomy is still treatment After Cataract at present
Main means, but also bring a series of complication, including IOL damage, postoperative intraocular pressure increase, macular cystoid edema, view
Film is detached from and IOL dislocation.
Therefore, the prior art can not prevent the generation of inverse position method well, and clinically there are no a kind of effective at present
Method prevents and treats inverse position method.
In addition, intraocular lens are generally made of transparent material in ophthalmic applications, it is divided into optics area and Support.
Optics area is located at intraocular lens centre, for changing the refractive status of human eye, realizes the purpose of optical imagery.Support portion
Divide and be called support button loop, can be template, L-type, c-type etc., for intraocular lens' supporting and fixing in human eye.Optics area and
Support can be made of same material, can also be made of not same material.The intraocular implants made of soft material
Body can fold, be implanted into intraocular intraocular implants after this folding or curling under rolled state by a lesser notch
Body being capable of Automatic-expanding after entering human eye.
In field of ophthalmology, the optics area of ophthalmic lens (such as intraocular lens) generally comprises former and later two curved tables
Face since its material refractive index is different from intraocular aqueous humor refractive index, and generates the effect of dioptric, refraction.Ophthalmic lens are (as manually
Crystalline lens) optics area generally comprise optical lens, be located at ophthalmic lens (such as intraocular lens) center, be ophthalmic lens
(such as intraocular lens) realize the core part of dioptric function, and part ophthalmic lens (such as intraocular lens) are with outside optics area
The structure being connected with support section.After ophthalmic lens (such as intraocular lens) are implanted into eye, optics area is placed in the middle, ophthalmic lens (such as people
Work crystalline lens) with eye own optical structure collectively constitute an optical system.Ophthalmic lens (such as intraocular lens) optics area packet
Containing optical imaging moieties, does not allow generally to be blocked, interfere.
All there are some non-predetermined light and finally throw on imaging surface in any optical system, these light due to many reasons
Line is referred to as stray light, it is the interference light beam for influencing optical system normal imaging.Most of stray light is not imaged in image planes,
And a bright background is generated in image planes, decline picture contrast, influences image quality;There are also the mesh of some high brightness
Mark can form ghost image (also referred to as secondary picture) in image planes.The presence of interference light can be such that patient experiences after implantable artificial crystalline lens
To bad optical phenomenas such as ghost, dazzle, abnormal specks.
For ophthalmic lens (such as intraocular lens) in this optical system of eye, interference light and ghost image main source have two
Kind: one is the additional image generated near optical system focal plane due to lens surface multiple reflections, this ghost image mainly leads to
The reasonable optical surface profile of lens front and rear surfaces is crossed to be designed to deal with or alleviate.Another kind is that light is incident to rims of the lens, by side
The reflection of edge section or refraction form harmful light, and this harmful light is affected to visual effect, and patient is postoperative often anti-in clinic
Phenomena such as " now side have tear sense " of feedback, " having bright ring/bright border ", " edge glare ", is caused by the interference light of the type.Especially
It is the refractive index that the Refractive Index of Material of ophthalmic lens (such as intraocular lens) is generally higher than surrounding aqueous humor, light by refractive index compared with
High optically denser medium is incident on the lower optically thinner medium of refractive index, and light is oblique incidence, and incidence angle is generally very big, is easy to
Total reflection phenomenon is generated, light is all reflected to human eye after being incident to intraocular lens edge, by severe jamming visual quality.
The artificial crystalline lens material higher for refractive index, this phenomenon are more serious.It is known in those skilled in the art to be, total reflection
Refer to when light is incident on optically thinner medium by optically denser medium, and incidence angle is greater than Brewster's angle, light will all be reflected
Phenomenon.
The mode for solving intraocular implants' marginal interference light at present is mainly alleviated by edge shape design and surface treatment,
Reflection as attempted reduction marginal interference light in United States Patent (USP) US6884262 using the edge shape of special gradient, the U.S. are special
The mirror-reflection at edge is become by diffusing reflection using frosted edge in sharp US8012203, reduces interference light and ghost image.These sides
Method has relaxation effect for rim ray reflection, but can not accomplish to eliminate comprehensively.The method bevel angle list that US6884262 is used
One, it is only capable of playing the role of elimination to part interference light;The local frosted processing of US8012203 is upper extremely difficult in technique realization,
And diffusing reflection still will form certain interference light, only the brightness of light be interfered to be reduced and alleviate.
Inventor's discovery, the medical device (such as lens) by providing a kind of specific structure can solve above-mentioned each
Kind problem, such as reduce bad optical phenomena, reduce the problems such as marginal interference light and local treatment (such as preventing inverse position method), and
It can be used for device relevant to optical medical devices, as ophthalmic lens (for example, intraocular lens), frame eyeglasses, cornea connect
It touches mirror built in mirror (contact lenses), cornea, have the various ophthalmic lens such as crystal Pseudophakia (implanted contact lenses).
