A mechanical model of the eye considering it as a cable-driven parallel kinematics mechanism is proposed. The inverse kinematics of the eye is carried out and theisodeformation curves of the extraocular muscles are obtained. The results agree with those previously reported by other, more complex, analytical approaches and with physiological measurements. This effort is a contribution to the modeling ofthe kinematics of the eye from the standpoint of robotics and mechanism theory and it could be used in eye movement studies to explore brain function. This work may support the neurologically-constrained argument for the positioning of theeye.
