Description
Technical field
The present invention relates to there is crystal eye intraocular lens, relating more specifically to posterior chamber type has crystal eye intraocular lens.
Background technology
Posterior chamber type is made of crystal eye intraocular lens opticator and support section, be implanted to natural lens with
Between iris, button loop is supported in ciliary groove, as shown in Figure 1, to change the refractive status of human eye, it is near particularly to correct height
Depending on.
For having crystal eye intraocular lens, except realize correction of refractive errors function in addition to, it is important the considerations of factor be
The structure of intraocular lens is for the security after implantation.
Enough spacing must be kept between corneal endothelium, natural lens after having crystal eye intraocular lens implantation, prevented
Only trigger corneal endothelium damage or natural lens muddy due to intraocular lens contacts with corneal endothelium and natural lens.By
Space is extremely limited between iris and natural lens, therefore surgical procedure difficulty is big, and to the size of intraocular lens just like
Lower strict requirements：
1）Spacing between intraocular lens and natural lens is enough, prevents two kinds of crystalline lenses from contacting with each other, causes contact
Cataract, this requires intraocular lens to have enough springs of arch；
2）Spacing is enough between intraocular lens and corneal endothelium, prevents intraocular lens from being contacted with corneal endothelium, causes cornea
Endothelial injuries, this requires the spring of arch of intraocular lens cannot be excessively high；
3）Intraocular lens's overall length must be matched with ciliary groove size so that intraocular lens can be just stuck in ciliary groove.
If intraocular lens is long compared with ciliary groove, intraocular lens will arch upward, though away from natural lens, in cornea
Bark graft is near, easily causes corneal endothelium damage, and room angle is oppressed, and easily causes room angle closure, and causes the complication such as glaucoma；
And if intraocular lens is too short compared with ciliary groove, easily cause intraocular lens's support force insufficient, under iris compressing with day
Right lens contact, and cause cataract.
In addition, there is following Consideration in the design aspect of intraocular lens：
1）Room angle：As intraocular lens is implanted, human eye iris is influenced by intraocular implants' shape, is arched upward slightly, will be made
Human eye room angle becomes smaller, as shown in Figure 2.If room angle is closed, i.e., iris is extremely close with cornea interior surface, and room angle approaches to turn off shape
State（Nearly 0 degree of room corner connection）, then the complication such as room angle closed intraocular hypertension, glaucoma are caused, therefore intraocular lens should in design
Reduce the influence caused by room angle as far as possible, the room angle of bigger is reserved for human eye.
2）Opticator：Refer to the circular diameter containing optical design features for being concentric with intraocular lens's optical axis, human eye is dim
Under the conditions of pupil expand, to prevent glare problem, the opticator of intraocular lens should try one's best greatly.
In conclusion in order to ensure the security and validity after artificial lens implanting, it should ensure intraocular lens
As far as possible big opticator, as far as possible more intraocular lens with natural lens and with the gap of corneal endothelium, it is as far as possible big surplus
Remaining room angle.However, there is mutually restriction between opticator size and remaining room angle and between spring of arch and remaining room angle
Relation, for an equal amount of human eye, intraocular lens's opticator is bigger, then the point that intraocular lens contacts with iris is got over
Close to room angle, the degree that iris is arched upward is higher, and remaining room angle is smaller.Likewise, intraocular lens vault Gao Yuegao, then iris
The degree to be arched upward is higher, and remaining room angle is also smaller.
Existing ciliary groove support at present, posterior chamber type have the ICL of crystal eye intraocular lens only STAAR companies production.For
Make intraocular lens with corneal endothelium distance enough, existing posterior chamber type have crystal eye intraocular lens using it is preceding it is flat after it is recessed
Structure realizes the diopter that intraocular lens bears.
The problem of this design, is that, when intraocular lens's diopter is larger, rear surface radius of curvature is smaller, optical section
Point edge is easily contacted with human eye natural lens, and causes natural lens that friction is locally subject to cause cataract.In order to reduce
This risk can take the mode of increase sagitta, make intraocular lens's rear surface whole with natural lens keep safety away from
From.However, with the angle that the increase of sagitta, human eye iris are formed with cornea interior surface, i.e. room angle becomes smaller, and room angle is easily caused to be closed
Mould assembly glaucoma.Therefore existing intraocular lens reduces opticator, so as to reduce light by the way of opticator size is sacrificed
It learns part edge to thicken caused by diopter, ensures to leave sufficient space between intraocular lens and natural lens, and
Keep the stabilization at room angle.For example the ICL of STAAR, the diameter maximum of intraocular lens's opticator are only capable of reaching 5.5mm, with
The increase opticator of diopter constantly reduces, and is only capable of maintaining the opticator of a diameter of 4.65mm big for the diopter of -20D
It is small.
Intraocular lens's opticator small the problem of causing dazzle, influence contrast sensitivity, especially pupil of human compared with
In the case of big, such as dim, night-environment, existing posterior chamber type have the complication of the common postoperative dazzle of crystal eye intraocular lens.And
And clinical medicine statistical result shows that the pupil of high myopia is generally bigger than normal eye, therefore existing intraocular lens
The smaller design of the higher opticator of diopter more easily causes glare problem.
Fig. 3 shows that two panels has the intraocular lens 1,2 of preceding flat back concave surface shape.The high phase of vault of intraocular lens 1,2
Together.The absolute value of the diopter of intraocular lens 1 is less than the absolute value of the diopter of intraocular lens 2, after intraocular lens 1
Surface curvature radius R1 is more than the rear surface radius of curvature R 2 of intraocular lens 2.At identical diameter, intraocular lens 1 from
The spacing of natural lens is more than spacing of the intraocular lens 2 from natural lens.In order to increase intraocular lens 2 and natural crystalline
The spacing of shape body is, it is necessary to reduce the opticator of intraocular lens 2.
That is, the intraocular lens that the absolute value of diopter is bigger, rear surface radius of curvature is smaller, and rear surface is steeper
It is high and steep, it is nearer from natural lens at identical optical diameter, in order to increase gap, using the method for reducing opticator.
In addition, for the intraocular lens of double spherical designs, the spherical aberration entrained by intraocular lens itself will
Human eye vision quality can be impacted, the big intraocular lens of spherical aberration generates dazzle easily at night or larger pupil of human and shows
As.Fig. 4 shows the relation of intraocular implants' body front surface of negative diopter and the face shape of rear surface and self-contained spherical aberration.It can
See, the self-contained spherical aberration of preceding flat rear recessed negative diopter intraocular lens is maximum.Therefore existing at present there is the crystal eye manually brilliant
A large amount of spherical aberrations can be brought to human eye after the implantation of shape body, influence human eye vision quality, especially dim condition or pupil of human is larger
In the case of visual quality.
The content of the invention
