摘要：
A switchable intraocular lens assembly includes an optic body having a guiding surface, a holding chamber, a blocking channel, and a laser accessible cavity at a portion of the blocking channel. An elastic film is disposed over the guiding surface, wherein the elastic film is sealed at or near the guiding surface periphery forming a transparent chamber between the guiding surface and the elastic film. A laser flowable blocking element has an enlarged head connected to an extension portion, where a length of the extension portion is more than a distance along the blocking channel from the blocking channel opening to the fluidic connection of the transparent chamber. The extension portion of the laser flowable blocking element is disposed inside the blocking channel. An optical fluid is disposed within the holding chamber under a pressure greater or lesser in comparison to a pressure in the transparent chamber.
摘要（中）：
可切换的眼内透镜组件包括在阻挡通道的一部分处具有引导表面的光学主体，保持腔，阻挡通道和激光可触及腔。 弹性膜设置在引导表面上，其中弹性膜在导向表面周围或附近被密封，在引导表面和弹性膜之间形成透明室。 激光可流动阻挡元件具有连接到延伸部分的扩大头部，其中延伸部分的长度大于沿着阻挡通道从阻挡通道开口到透明腔室的流体连接的距离。 激光可流动阻挡元件的延伸部分设置在阻挡通道内。 光学流体在与透明室中的压力相比更大或更小的压力下设置在保持室内。
