Description
Technical field
The present invention relates to intraocular lens system technical field, specially a kind of novel intraocular lens system.
Background technique
Senile macular degeneration (AMD) is generally acknowledged one of the most refractory eye disease of international ophthalmic industry, and causes patient
Blindness one of the main reasons, senile macular degeneration increasingly increase in Chinese (AMD) disease incidence, and total patient population has reached at present
5000000, the patient of advance macular geographic atrophy accounts for ten thousand people of 50%(250), and in the trend risen.Senile macular degeneration meeting
Macula retinae region photosensory cell is caused seriously to be lost, this damage usual situation can all cover central fovea of macula region.This
The eyesight in a little regions is related to reading and face recognition eyesight in daily life, so most important.
Most of patients with macular degeneration loses most photosensory cells of macula lutea center between the illness several years, only
Central area remains with island shape region by macula lutea, possesses normally functioning Retina.But this part isolated island region is still
It cannot be used for reading, because the central fovea of macula in foveal region of retina region possesses highest photoreceptor density, also correspond to highest
Image resolution ratio and eyesight it is horizontal.As viewed area deviates central fovea of macula region, under photoreceptor distribution density is significant
Drop, the normal isolated island region of patients with macular degeneration photosensory cell are usually located at central fovea of macula and deviate optical axis 3-5 degree range, institute
With the view level of resolution of isolated island part only in relation to 30% or so of macula lutea central area eyesight.Reading and face recognition, still
It is so very problematic, seriously affect the living standard of Age related macular deformation patient.
According to the different severity of patient's vision defect, patient wants to improve eyesight, it is necessary to by means of helping view equipment.Example
Such as, the magnifying glass of wear-type or hand-held help is read and other situation needs.Equipment is watched attentively using these, and there are convenient
Property, brightness of illumination limitation, the problems such as limits vision.
Now, cataract operation uses intraocular lens, substitutes natural human lens, helps patient to restore eyesight, has become
To implement most operations in ophthalmology.The offset and adjustment of imaging optical axis are not considered in the implantation process of existing intraocular lens
Structure, and do not consider the factors such as the visual axis tilt of human eye ball, pupil decentration so that adjustment effect is poor, and operative incision compared with
Greatly, corneal astigmatism degree is more serious.
Summary of the invention
The purpose of the present invention is to provide a kind of novel intraocular lens systems, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the invention provides the following technical scheme: a kind of novel intraocular lens system, including rear group saturating
After mirror and preceding group of lens, it includes at least one first lens that lens are organized after described, and the rear group lens are inside eyeball
Before cyst membrane, it also includes at least one second lens that lens are organized before described, and the preceding group lens are arranged in inside eyeball
Lens and the rear group lens are organized around the imaging system of the optical axis formation rotational symmetry of eyeball in the side of iris before described.
Preferably, first lens are specially the single-positive-lens for having the positive diopter of preceding light pass surface and rear light pass surface,
Wherein preceding light pass surface and rear light pass surface are at least aspherical on one side.
Preferably, second lens are specially the single-positive-lens for having the negative diopter of preceding light pass surface and rear light pass surface,
Wherein preceding light pass surface and rear light pass surface are at least aspherical on one side.
Preferably, before described position of the group lens inside eyeball be specially be located between the Lens capsular of eyeball and iris and
Any one between the iris of eyeball and the cornea of eyeball in two kinds of positional relationships.
Preferably, first lens and the second lens realize lens light after being implanted into eyeball by supporting mechanism for location respectively
The sloped position of school district.
Preferably, the supporting mechanism for location is specially any one in two kinds of the first positioning mechanism and the second positioning mechanism
Kind.
Preferably, first positioning mechanism includes that the first support is climbed and climbed with the second support, and first support is climbed and the
Two supports climb difference asymmetric distribution in the outside of the lens light school district of first lens and the second lens.
Preferably, second positioning mechanism includes that frame is climbed in support, and the support, which is climbed, offers intermediate cavity on the inside of frame, institute
The optics of lens area for stating the first lens and the second lens is slidably connected at the inside that the intermediate cavity of frame is climbed in support respectively, to complete
By the adjusting of the deviation post to optics area, the adjusting that fine location is imaged on eye ground is obtained.
Compared with prior art, the beneficial effects of the present invention are:
By the position of rear group of lens and preceding group of lens, the dynamic adjustment of the clear area of eyeball prosthomere imaging is realized, with macula lutea
The eye ground situation for being denaturalized patient is adapted, and full resolution pricture is projected to retinal photoreceptor cells extent of damage lowest region
Domain.
