High definition and extended depth of field intraocular lens

A method of treating an eye, comprising:

• implanting an ocular implant into the eye, the ocular implant comprising:
• an optical zone comprising at least one anterior optical surface and at least one posterior optical surface;
• a first periphery region peripherally positioned relative to the optical zone, the first periphery region comprising a virtual aperture, the virtual aperture comprising an anterior virtual aperture surface and a posterior virtual aperture surface;
• and
• a second periphery region peripherally positioned relative to the first periphery region, the second periphery region comprising a haptic for positioning the intraocular lens within an eye, wherein the haptic comprises an outermost region of the intraocular lens;
• wherein a first plurality of light rays incident on the anterior optical surface pass through the optical zone to form an image on a retina when the intraocular lens is implanted in the eye;
• and
• at least one of:
• (a) a first surface contour on an anterior surface of the intraocular lens, the first surface contour comprising at least one annular region;
• and
• (b) a second surface contour on a posterior surface of the intraocular lens, the second surface contour comprising at least one annular region;
• wherein a second plurality of light rays incident on the anterior virtual aperture surface are dispersed widely downstream from the intraocular lens towards and across the retina, such that the image comprises the extended depth-of-field and further wherein said virtual aperture reduces monochromatic and chromatic aberrations in the image;
• wherein the second surface contour comprises a micro-prism array, and
• wherein the array of micro-prisms across the micro-prism region is not uniform.
