    • An intraocular lens (IOL) insertion apparatus for implanting IOLs through smaller incisions. The insertion apparatus includes an insertion cartridge that receives the IOL and cooperates with a handpiece. The cartridge includes a longitudinal lumen from al loading chamber to an open distal mouth that gradually narrows in dimension. A push rod having an extremely soft tip thereon urges the IOL through the cartridge and from the open distal mouth. The soft tip (130) is made of low-stimulus material having a minimum ultimate elongation of 400%. Because of the extremely soft material of the tip, the outside diameter of the open distal mouth can be reduced to no more than 2.00 mm, enabling passage through incisions of 2.2 mm or less. The soft tip may be a thermoplastic elastomer having a relatively high elongation and relatively low modulus at elongations of 100-300%.
    • 一种用于通过较小切口植入IOL的人工晶状体(IOL)插入装置。 插入装置包括容纳IOL并与手持件配合的插入盒。 药筒包括从装载室到开口的远端口的纵向腔,其逐渐变窄。 具有非常软的尖端的推杆通过盒和从开放的远端口引导IOL。 软尖端(130)由具有最小极限伸长率为400%的低刺激材料制成。 由于尖端的材料非常柔软,所以开放的远端口的外径可以减小到不超过2.00mm,能够穿过2.2mm以下的切口。 软尖端可以是在100-300%的伸长率下具有相对高的伸长率和相对低的模量的热塑性弹性体。
