A cartridge (10) for an intraocular lens (IOL) delivery system is provided that is specifically designed to aid in wound assisted IOL delivery. The distal tip (16) of the nozzle (14) has an extended canopy (20) which serves to open the incision and support the IOL. Peripheral protrusions (22), flanges, or stops extending laterally from the side of the distal tip provide a positive depth limitation, and prevent the full insertion of the nozzle into the incision. In addition, the protrusion (22) provides support to the incision to reduce the tendency of wound damage through tearing.一種用於IOL輸送系統的卡匣，該IOL輸送系統係經特別設計可輔助傷口輔助IOL輸送。該噴嘴的遠端尖端有一用來打開切口以及支撐IOL的伸出罩蓋。由遠端尖端側面橫向伸出的外周突出物、凸緣、或擋板係提供主動的深度限制，以及防止該噴嘴完全插入切口。該突出物也支撐切口以降低傷口因撕裂而受傷的傾向。
