Abstract

The present invention relates to devices, systems, and methods for optimizing peripheral vision. In particular, methods are disclosed which include utilizing particular characteristics of the retina in optimizing peripheral vision. Additionally, various IOL designs, as well as IOL implantation locations, are disclosed which optimize peripheral vision.

Claims

1. A method of optimizing peripheral vision, comprising:

determining one or more physical and/or optical properties of the retina;

selecting an IOL based on the one or more physical properties of the retina; and

determining an axial position of an IOL.

2. The method of claim 1, wherein the principal plane of the IOL or IOL system is between about 1.9 mm and 2.9 mm behind the iris.

3. The method of claim 1, wherein the principal plane of the IOL or IOL system is between about 2.9 mm and 3.9 mm behind the iris.

4. The method of claim 1, wherein the principal plane of the IOL or IOL system is between about 3.9 mm and 4.5 mm behind the iris.

5. The method of claim 1, wherein the optical properties of the retina include a geographical map of retinal functionality

6. The method of claim 1, wherein the optical properties of the retina include the shape of the retina.

7. An IOL for optimizing peripheral vision, comprising:

an optic;

and an element that extends the depth of focus off-axis.

8. The IOL of claim 7, wherein the optic comprises:

a singular circular surface structure with an inner portion, an outer portion, and a transition zone that connects the inner and outer portions, wherein the transition is characterized by a step height having a value within a range from about 0.5 microns and about 4 microns.

9. A multifocal IOL for optimizing peripheral vision comprising:

an optic which produces at least two foci having essentially the same dioptric power.

10. The multifocal IOL of claim 9, wherein, the add powers of the at least two foci are about zero diopters.

11. The multifocal IOL of claim 10, wherein the optic is comprised of at least two zones with each zone focusing an image at a different part of the retina.

12. The multifocal IOL of claim 11, wherein the inner zone is spherical and the outer zone consists of a spherical lens combined with a prism for focusing an image at a predetermined spot in the periphery.
