Intraocular lens with increased depth of focus and methods for increasing a depth of focus of an intraocular lens

A method of forming a pinhole intraocular lens (IOL), comprising:

• directing laser light at a first layer of an optic portion of an IOL in a first spiral pattern until a first opaque mask layer is formed within the optic portion, wherein the IOL has a refractive power configured to adjust a refractive power of an eye to between about −0.7 diopters and about −0.9 diopters when the IOL is implanted within the eye;
• and
• directing the laser light at a second layer of the optic portion of the IOL in a second spiral pattern until a second opaque mask layer is formed within the optic portion,
• wherein the first opaque mask layer is not aligned with the second opaque mask layer in an anteroposterior direction.

An intraocular lens (IOL), comprising:

• an optic portion and one or more haptics coupled to the optic portion;
• and
• an opaque mask formed within the optic portion,
• wherein the opaque mask encloses a pinhole,
• wherein the opaque mask is comprised of multiple mask layers, and
• wherein at least one of the multiple mask layers is not aligned with another one of the multiple mask layers in an anteroposterior direction.
