A shape memory polymer (SMP) intraocular lens may have a refractive index above 1.45, a Tg between 10° C. and 60° C., inclusive, de minimis or an absence of glistening, and substantially 100% transmissivity of light in the visible spectrum. The intraocular lens is then rolled at a temperature above Tg of the SMP material. The intraocular device is radially compressed within a die to a diameter of less than or equal to 1.8 mm while maintaining the temperature above Tg. The compressed intraocular lens device may be inserted through an incision less than 2 mm wide in a cornea or sclera or other anatomical structure. The lens can be inserted into the capsular bag, the ciliary sulcus, or other cavity through the incision. The SMP can substantially achieve refractive index values of greater than or equal to 1.45.
形状记忆聚合物(SMP)眼内透镜的折射率可高于 1.45,Tg 介于 10 摄氏度和 60 摄氏度之间(包括 60 摄氏度),极少或没有闪烁,对可见光谱的透光率基本上为 100%。然后在高于 SMP 材料 Tg 的温度下轧制眼内透镜。眼内装置在模具内径向压缩至直径小于或等于 1.8 毫米,同时保持温度高于 Tg。压缩后的眼内透镜装置可通过角膜或巩膜或其他解剖结构上小于 2 毫米宽的切口插入。晶状体可通过切口插入囊袋、睫状沟或其他空腔。SMP 的折射率可达到大于或等于 1.45。
