Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
69 words
A method for measuring torque on an eyeball to correct a strabismus condition, comprising the steps of: displacing the eyeball in a single plane by means gripping the eyeball's sclera to exert a force on the eyeball sufficient to correct the condition while isolating any forces outside the single plane from being exerted on the eyeball; and simultaneously with said displacing step, measuring the force exerted on the eyeball.
Claim 2
Independent Claim
69 words
A method for measuring torque on an eyeball to correct a strabismus condition, comprising the steps of: displacing the eyeball in a single plane by means gripping the eyeball's sclera to exert a force on the eyeball sufficient to correct the condition while isolating any forces outside the single plane from being exerted on the eyeball; and simultaneously with said displacing step, measuring the force exerted on the eyeball.
Claim 3
Dependent Claim
19 words
A method according to claim 1 further including the step of utilizing a reverse-action clip as the gripping means.
Claim 4
Independent Claim
22 words
A method according to claims 1 or 2 further including the step of utilizing a Pierse-type forceps tip in said gripping means.
Claim 5
Dependent Claim
36 words
A method according to claim 1 wherein said measuring step includes the steps of attaching the gripping means to a force gage and transmitting only nasal and temporal displacements of the eyeball to the force gage.
Claim 6
Dependent Claim
71 words
A method according to claim 4 in which the force gage has an arm moveable in the single plane and wherein said transmitting step includes the step of moving the force gage arm generally parallel to the nasal and temporal displacements and pivoting the gripping means to the force gage arm for moving the gripping means in the single plane which is orthogonal to the plane in which the arm moves.
