Technical field
The present invention relates to a kind of new mesopic vision rectification type aspheric intraocular lens completely（IOL）.Specifically,
The present invention relates to a kind of spherical aberration value is about -0.1 ~ -0.2 μm of aspheric intraocular lens, wherein correspond to a diameter of of pupil
4.5mm..
Background technology
Cataract, as the main cause leading to people's blinding, has caused the attention of more and more people, with people's age
Increase, human eye natural lens cognition gradually thickens, or even loses transmittancy, ultimately results in human eye complete Loss Of Vision work(
Energy.
Extract lighttight human lenses, implantable artificial crystalline lenses are the optimum selections recovering human eye vision, from 1949
The intraocular lenss that year Britain is made using hard PMMA material first, successfully achieve lens replacement operation, intraocular implants
Body and corresponding surgical technic have obtained swift and violent development, so far it is already possible to realize diffraction using flexible material many
Focus or even zoom IOL, and be successfully applied in clinic.
Fig. 1 is the dioptric schematic diagram of human eye, and from optical angle, human eye is by corneaaAnd crystalline lensesbTwo main
The optical system of lens composition, pupilcIt is the aperture diaphragm of whole optical system, retinadIt is imaging surface, whole system is suitable
In being immersed in liquid solution.Cornea, as topmost optical power element, assume responsibility for the focal power of eyes more than 2/3rds, brilliant
Shape body undertakes remaining 1/3rd diopters.The cornea of human eye carries certain positivity spherical aberration, and the size of its value varies with each individual,
Substantial amounts of clinical trial shows, the distribution of its spherical aberration value meets normal distribution law, and in the case of 6mm pupil, intermediate value is about
0.27 μm, when extraneous light enters human eye, under bright light environments, the pupil of human eye is less（Below 3mm）, now the spherical aberration of cornea is relatively
Little, light is paraxial rays, can become gem-pure picture on the retina, and the visual condition of human eye is good, but in night vision
In the case of（Pupil 6mm about）, the spherical aberration of cornea is larger, and the refractive power through CC region and marginal area for the light is bright
Aobvious difference, the refractive power of central area is weak, and the refractive power of marginal area is stronger, and the natural lens of human eye itself can be mended
Repay the positive spherical aberration that cornea brings so that the Integral ball differential of eyes is bordering on zero, therefore, no matter bright or scotopia or
At night, all there is good visual effect.
Itself there is positive spherical aberration in traditional sphere intraocular lenss, it, on the basis of the positive spherical aberration of cornea itself, increased
Total spherical aberration of human eye, affects postoperative visual quality.Patient therefore will be made to obtain more preferably visual effect it is necessary to reduce postoperative eye
Total spherical aberration.Aspheric intraocular lens are based on that this is theoretical and research and develop, by the aspheric design of plane of crystal so as to
There is zero spherical aberration or negative spherical aberration, so that total spherical aberration of postoperative eye remains at low levels, thus solving common sphere intraocular implants
Body in the case of big pupil, the problem that contrast declines, improve the visual capacity under half-light and night-environment.AMO company
Tecnis Z900 type intraocular lenss are the intraocular lenss that the first can produce negative spherical aberration, produce -0.27 μm of negative ball
Difference, equal with the average spherical aberration statistical data of cornea, design concept is to be completely counterbalanced by the positive spherical aberration of cornea.Alcon company sets
The aspheric intraocular lens Acrysof SN60WF of meter, after optical section, surface adopts aspheric design, can produce -0.2 μ
The negative spherical aberration of m is it is intended to keep a certain amount of positive spherical aberration for full eye, to obtain more preferable visual comfort.Bausch ＆ lomb is public
The aspheric intraocular lens of department entitled SofPort AO and AkreosAO of release, crystal aberrationless itself, will not be to whole
Individual human eye introduces extra spherical aberration, also referred to as zero spherical aberration crystal.
However, the aspheric faceted crystal of -0.27 μm of negative spherical aberration, to crystalline lenses during implantation and postoperation recovery, exist
Bias and tilt very sensitive, even slight bias, the characteristic limited by aspheric surface crystal diffraction will disappear, because
This this crystalloid is in fact very high to the accuracy and required precision of implant surgery.Zero spherical aberration（No spherical aberration）Crystal no ball itself
Difference, or even in bias, do not introduce coma yet, therefore can effectively reduce the impact that crystal is eccentric and inclination is to image quality,
But this design there is problems that, because crystal itself does not offset the positive spherical aberration of cornea, in mesopic vision and scotopia
It will be apparent that limiting visual effect in the case of feel.
In sum, the present invention proposes a kind of new intraocular lenss, and this crystal can be completely counterbalanced by mesopic vision feelings
The spherical aberration of cornea under condition, thus human eye visual quality under bright and dark situation is substantially improved, part compensates human eye simultaneously
Cornea spherical aberration in the case of night vision, takes into account its image quality, more importantly, reduce operation implantation process in crystal inclined
The impact to image quality of the heart and inclination, it is true that human eye is in most cases, is all to be operated in bright and Crape ring
Under border, therefore, the image quality in the case of effective lifting mesopic vision, and sufficiently consider follow-up implant surgery to imaging matter
The impact of amount, provides a kind of crystal type of more balance and is necessary..
