above the lens 30 will not rotate or shift within the capsule 20 implantation of the inventive lens 30 restores normal vision because not only does the lens 30 replace the patient 39 s occluded natural lens but the normal responses of the ciliary body 24 cooperate with the lens 30 during focusing in fig1 the capsule 20 is shaped for viewing an object distant from the eye 10 that is in order to view an object distant from the viewer the ciliary body 24 has retracted thus pulling on the zonular fibers 26 making the capsule 20 and thus the lens 30 more discoid in shape this change in shape causes the optic 32 to become thinner i e there is a decrease in the horizontal depth of the optic 32 so that it has a thickness t d as used herein the thickness of the optic is intended to be the thickness at approximately the center of the optic optic 32 is formed of a solid liquid or gel material e g silicone so it has a refractive index greater than that of the surrounding fluid in the eye i e greater than 1 33 this refractive index combined with the thinness of optic 32 as shown in fig1 results in a less convergent lens which makes distance viewing possible referring to fig2 the ciliary body 24 has contracted making the capsule 20 more spheroid in shape as a result the optic 32 has had an increase in thickness.
