Abstract
Abstract An instrument for use in human cataract or glaucoma eye surgery which is inserted into the inferior cul-de-sac of the eye in order to rotate the eyeball downward for exposure of the upper eyeball sclera for surgery. The present instrument avoids the need for sutures or stitches to rotate the eyeball down, thereby avoiding the possibility of ptosis, and unnecessary wounds and their associated possibilities of hemorrhage, discomfort, slow healing and infection. The instrument includes a pair of arms with intermediate curls and a terminating crossbar.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
136 words
An instrument for rotating the globe of a human eye downward during eye surgery comprising a pair of arms which are joined at one end forming a joint, and a rubber band attached to said joint, wherein each of said arms includes a first portion which cooperatively extends away from said joint along a horizontal axis, a second portion in which the arms cooperatively curl downward from the horizontal axis forming a first set of curls, and a third portion in which opposite ends of the arms each extend further to a terminating cross bar, said terminating cross bar connecting said opposite ends together transverse to a longitudinal axis of each of the arms, whereby when the instrument is placed in the inferior cul-de-sac and tension is applied to the rubber band the eye globe rotates.
Claim 2
