眼内透镜及其制造方法
摘要：
一种具有新颖结构的眼内透镜包括足够大的有效光学部件并产生对继发性白内障的优良抑制作用。眼内透镜的透镜表面(16，18，30)的至少一部分是细胞诱导区(26，32)，在所述细胞诱导区(26，32)中直接形成大量线状微槽(28)，所述微槽(28)具有0.01到1.0μm的深度、0.1到2.0μm的宽度和预定长度并沿周向延伸。所述微槽(28)沿所述透镜表面(18，30)的圆周方向连接而构成链接图形，并沿所述透镜表面(18，30)的径向周期性排列而构成周期性图形。由于在所述线状微槽之间没有间隔地在整个细胞诱导区(26，32)内形成所述线状微槽(28)，所述细胞诱导区(26，32)中的可见光透射率为60％以上。
摘要（英）：

An intraocular lens having a novel structure including an adequately large effective optical part and producing an excellent suppressing effect on a secondary cataract. At least a part of the lens surfaces (16, 18, 30) of an intraocular lens is cell inducing regions (26, 32) where a large number of linear micro-grooves (28) having depths of 0.01 to 1.0 [mu]m, widths of 0.1 to 2.0 [mu]m, and predetermined lengths, circumferentially extending are directly formed. The micro-grooves (28) are connected in the circumferential direction of the lens surfaces (18, 30) to construct a chaining structure and are periodically arrayed in the radial direction of the lens surfaces (18, 30) to construct a periodic structure. The transmittance to visible light in the cell inducing regions (26, 32) is 60% or more thanks to the formation of the linear micro-grooves (28) over the whole cell inducing regions (26, 32) with no space between the linear micro-grooves.
