Abstract
Abstract An insertion guide for aiding the insertion of the superior haptic of an intraocular lens into the capsular bag of the eye during intraocular surgery. The guide is made of a thin, flexible material and has a body portion and a flap portion connected by an integral connecting portion which permits the flap to move from the first position folded against the body portion to a second position where the flap is disposed at an acute angle to the body portion so that the flap will act as a backstop to guide the superior haptic of an intraocular lens into the capsular bag. The present invention also relates to the method of inserting an intraocular lens using this guide.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
186 words
A lens insertion guide to facilitate the insertion of an intraocular lens into the capsular bag comprising: a thin, elongated body portion; a thin flap portion; a flexible, resilient connecting portion integrally connecting said flap portion and said body portion and permitting said flap to move from a first position, aligned with said body to facilitate insertion of said guide into the eye, to a second position disposed at a predetermined angle to said body portion to act as a backstop to facilitate proper insertion of a lens into the capsular bag; wherein said connecting portion permits said flap to move to a third position extending from said connecting portion in a direction away from said body portion and aligned generally parallel therewith to permit the lens guide to be easily removed from the eye; and further including a hollow insertion tube for said guide having an axial length shorter than the axial length of said insertion guide so that said flap may be moved from said second position to said third position for removal from the eye by merely pulling said guide through said tube.
Claim 2
Dependent Claim
186 words
