Abstract
An intraocular lens comprises an optic portion having a peripheral edge and at least two haptics. Each haptic is integrated with the peripheral edge of the optic portion by a corresponding haptic integration region. Also, each haptic comprises a distal segment region and a deformation segment region. The distal segment region has an outer distal length bounded by a proximate endpoint and a distal endpoint on an outer surface of the haptic, and is scribed by a distal segment angle α of 20° to 30°. The distal segment angle has a segment origin that lies within a radial segment bound by a radial distance 1.5 mm to 1.9 mm from an optic center and a segment angle θ of from 30° to 45° from a vertical axis. The vertical axis extends through the distal endpoint of at least one haptic and the optic center.
