Foldable intraocular lens and method of making
First Claim
1. A foldable intraocular lens, comprising:
- an optic body disposed about an optical axis and comprising an optical zone and a peripheral zone disposed about the optical zone, the peripheral zone having an outer radius of curvature, the optic body having an anterior face, a substantially opposing posterior face, and an optic edge comprising a face disposed between the anterior face and the posterior face; and
at least one haptic integrally formed with the peripheral zone, comprising;
a distal posterior face, a proximal posterior face, and boundary between the proximal posterior face and the distal posterior face, the distal posterior face being offset in a direction along the optical axis from the proximal posterior face at the boundary;
the proximal posterior face of the haptic and the posterior face of the optic body forming a continuous surface bounded by the optic edge and the boundary between the proximal posterior face and the distal posterior face;
the boundary having a profile about the optical axis that includes a rounded tip.

Abstract
A foldable intraocular lens for providing vision contains an optic body that includes an optical zone and a peripheral zone entirely surrounding the optical zone. The optic body has an anterior face, a substantially opposing posterior face, an optic edge, and an optical axis. The anterior face comprises a central face, a peripheral face, and a recessed annular face therebetween that is disposed posterior to the peripheral face. The intraocular lens further comprises at least one haptic that is integrally formed with the peripheral zone. The haptic comprises a distal posterior face, a proximal posterior face, and a step edge disposed at a boundary therebetween. The haptic further comprises a side edge disposed between the optic edge and the step edge. The proximal posterior face and the posterior face of the optic body form a continuous surface. An edge corner is formed by the intersection of the continuous surface with the optic edge, the side edge, and the step edge.
