Claim 1
Independent Claim
267 words
A tool for inserting an intraocular lens assembly into an eye, comprising: first and second members each having a first, a second and a third portion, said first portion of said first member and said first portion of said second member being flexibly engaged, said second portion of said first member angularly extending from said first portion of said first member and said second portion of said second member angularly extending from said first portion of said second member and said second portion of said first member and said second portion of said second member overlapping each other, said third portion of said first member angularly extending from said second portion of said first member, said third portion of said second member angularly extending from said second portion of said second member, said third portions of said first and second members respectively terminating opposite one another in a spaced apart relationship and said third portion of said first member and said third portion of said second member having means formed thereon for gripping an intraocular lens assembly; and actuating means for moving a securing pin carried by an intraocular lens assembly, said means being flexibly engaged to at least one of said members and extending therefrom to an area approximately between and above the terminus of the gripping portions of said third portions to engage said pin carried by said intraocular lens assembly when said assembly is held by said gripping means and thereby move said pin from a first position perpendicular to said means to a second position when pressure is applied to said actuating means.
