摘要：
Apparatuses, systems, and methods for implanting an intraocular lens into an eye are described. For example, an intraocular lens injector may include a plunger and an injector body that includes an insertion depth guard and a nozzle extending therefrom. The insertion depth guard is disposed at a distal end of the injector body to limit a distance that the nozzle penetrates the eye. The intraocular lens injector may also include a biasing element configured to generate a counterforce to distal movement of the plunger through the injector rod. An example intraocular lens injector may include a biasing element to produce a counterforce that opposes advancement of the plunger through the injector body. The counterforce provides for a more continuous advancement of the plunger while reducing or substantially eliminating abrupt changes in the rate at which the plunger is advanced through the injector body.本案描述用於將人工晶狀體植入眼睛之設備、系統及方法。舉例而言，人工晶狀體注射器可包括柱塞及注射器主體，該注射器主體包括插入深度防護件及自該插入深度防護件延伸之噴嘴。插入深度防護件安置於注射器主體之遠端以限制噴嘴穿透眼睛之距離。人工晶狀體注射器亦可包括偏置元件，該偏置元件經配置以產生針對柱塞穿過注射器桿之遠端移動之反作用力。示例性人工晶狀體注射器可包括偏置元件以產生抵抗柱塞穿過注射器主體推進之反作用力。反作用力在減少或大致上消除柱塞推進穿過注射器主體之速率之突然變化的同時提供柱塞之更連續推進。
