at medial segment 26 is only approximately between 0 16 mm and 0 14 mm 0 14 mm being preferred width 32 continues to narrow along the length of medial segment 26 so that as can be seen in fig5 width 32b of medial segment 26 at is narrowest point is only approximately 0 12 as can be seen in fig6 and 7 width 32 of haptic 14 increases along the distal portion of medial segment 26 so that at the intersection of medial segment 26 and distal segment 22 width 32c is approximately 0 14 mm width 32 of haptic 14 remains constant for the entire length of distal segment 22 so that at tip 28 width 32d remains approximately 0 14 mm maintaining a constant thickness 30 along the entire length of haptic 14 while having a varying width 32 from haptic origin 20 to tip 28 allows haptic 14 to flex but this flexing is primarily limited to planar flexing within or parallel to the plane of optic 12 and flexing of haptic 14 in the plane normal to the plane of optic 12 is minimized in addition the relative stiffness of distal segment 22 and proximal segment 24 compared to medial segment 26 causes haptic 14 to flex primarily along medial segment 26 thus medial segment 26 acts like a hinge allowing distal segment 22 to expand outwardly once iol 10 is fully inserted into the capsular bag the relatively shallow radius.
