INTRAOCULAR LENS IMPLANTING INSTRUMENT

摘要

An intraocular lens implanting tube in which a folded intraocular lens is moved smoothly through an introduction tube of the implanting tube such that a force is not applied unevenly to the intraocular lens and can be inserted into an eyeball easily while being coiled small. The transverse axis is longer than the longitudinal axis at the cross-section (8) of the insertion opening part (3), the longitudinal axis is longer than the transverse axis at the cross-section (9) of the intermediate part of the introduction tube (2), the transverse axis and the longitudinal axis are substantially equal at the cross-section (10) of the discharge opening part (4), the transverse axis changes continuously from the insertion opening part (3) toward the intermediate part to be gradually shorter, and the longitudinal axis changes continuously from the intermediate part toward the discharge opening part (4) to be gradually shorter.
