Foldable intraocular lens and method of making

A foldable intraocular lens, comprising:

• an optic body including an optical zone and a peripheral zone entirely surrounding the optical zone, the optic body having an anterior face, a substantially opposing posterior face, an optic edge, and an optical axis;
• at least one haptic integrally formed with the peripheral zone, comprising:
• a distal posterior face and a proximal posterior face;
• and
• a boundary between the proximal posterior face and the distal posterior face, the distal posterior face being offset from the proximal posterior face at the boundary in a direction along the optical axis;
• the proximal posterior face and the posterior face of the optic body forming a continuous surface;
• an edge corner comprising an intersection of the continuous surface with the optic edge and the boundary;
• the distal posterior face being perpendicular to the optical axis along a finite radial length.

A method of making a foldable intraocular lens, comprising:

• providing an optic body including an optical zone and a peripheral zone entirely surrounding the optical zone, the optic body having an anterior face, a substantially opposing posterior face, an optic edge, and an optical axis, the anterior face comprising a central face, a peripheral face, and a recessed annular face therebetween disposed posterior to the peripheral face, the recessed annular face encircling the optical axis;
• at the peripheral zone, integrally forming at least one haptic comprising a distal posterior face, a proximal posterior face, and a boundary therebetween, the distal posterior face being offset at the boundary from the proximal posterior face in a direction along the optical axis;
• forming the proximal posterior face and the posterior face of the optic body into a continuous surface;
• forming an edge corner comprising an intersection of the continuous surface with the optic edge and the boundary.

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, an opposing posterior face, and a wall face disposed between the anterior face and the posterior face, the anterior face comprising a central face, a peripheral face, and a recessed annular face therebetween disposed posterior to the peripheral face, the recessed annular face entirely surrounding a point along the optical axis;
• at least one haptic integrally formed with the peripheral zone, comprising:
• a distal posterior face and a proximal posterior face;
• and
• a step boundary between the proximal posterior face and the distal posterior face, the distal posterior face being offset at the step boundary from the proximal posterior face in a direction along the optical axis;
• a continuous surface comprising the proximal posterior face and the posterior face of the optic body;
• and
• an outer boundary edge comprising an edge corner, and the outer boundary surrounding the continuous surface and comprising the step boundary and an intersection of the continuous surface with the wall face.
