Art is implanted into the host crystal (1)；It is postoperative to select the additional transistor (2) of suitable class and degree if any residual concave-sphere or when cylindrical mirror,
Secondary implantation is carried out, and is detachably connected with what the host crystal (1) matched, to play the role of chasing after strong.The same period plants
Enter are as follows: when patient has low coverage in away from visual demand, select have the additional transistor (2) of diffraction ring or refracting sphere attached to provide
Add focus, the additional transistor (2) and the host crystal (1) same period are implanted into.
As another example, the same period implantation are as follows: when patient has low coverage in away from visual demand, selection has diffraction
The additional transistor (2) of ring or refracting sphere provides additional focus, and the additional transistor (2) and the host crystal (1) same period be implanted into
It is intraocular to patient.
In addition, not being resistant to person to symptoms such as the postoperative serious dazzles of appearance, the additional transistor (2) can be taken out at any time, are made
Eyes of patients become common single focus crystal state, thus dazzle caused by releasing because of additional transistor diffraction or refraction effect.
The double optics portion artificial lens external member of the embodiment of the present invention uses the detachable separation of host crystal and additional transistor
Structure, realizing only needs through replacement additional transistor without replacing whole artificial lens, manually brilliant to reach postoperative straightening
The purpose of body refractive error.In addition, can successively be implanted into host crystal and replaceable additional crystalline substance for the needs for the treatment of by stages
Body makes multiplicating surgical procedure become safer, simple, convenient.
Although being particularly shown and describing the present invention, those skilled in the art referring to its exemplary embodiment
It should be understood that in the case where not departing from the spirit and scope of the present invention defined by claim form can be carried out to it
With the various changes in details.
