Patent ID: 8449611

Claim:
An intraocular lens comprising an optic portion having a peripheral edge and at least two haptics, each haptic integrated with the peripheral edge of the optic portion by a corresponding haptic integration region, each haptic comprising a distal segment region and a deformation segment region, wherein the distal segment region has an outer distal length defined by a proximate endpoint and a distal endpoint on an outer surface of the haptic, the distal segment region scribed by a distal segment angle α of 200 to 300, and the outer surface of the distal segment region is arcuate with a radius of curvature of 4.3 mm to 5.7 mm, and the deformation segment region has an outer deformation length bounded by a proximate deformation endpoint on an outer surface of the haptic and the proximate endpoint of the distal segment region, the deformation segment region scribed by a deformation segment angle β of 20° to 40°, the distal segment angle and the deformation segment angle having a segment origin that lies within a radial segment bound by a radial distance 1.5 mm and 1.9 mm from an optic center and a segment angle θ of from 30° and 45° from a vertical axis, the vertical axis extending through the distal endpoint of at least one haptic and the optic center, wherein a portion of the outer surface of the distal segment region and a portion of the outer surface of the deformation segment region combine to form an angle of contact of not less than 52° and not more than 70° with an arcuate jaw if the haptics are concentrically stressed to a jaw diameter of 10 mm in accordance with ISO Test No. 11979-3(2006).
