1. A mask configured to be implanted in a cornea of a patient to increase the depth of focus of the patient, the mask comprising:
- an anterior surface configured to reside adjacent a first corneal layer;
a posterior surface configured to reside adjacent a second corneal layer;
a substantially opaque portion comprising an inner periphery;
a structure disposed within the opaque portion configured to provide an optical power for vision correction;
a plurality of irregularly located nutrient flow paths in the opaque portion, the nutrient flow paths configured to permit nutrient flow between the first corneal layer and the second corneal layer.

Abstract
A mask configured to be implanted in a cornea of a patient to increase the depth of focus of the patient includes an anterior surface, a posterior surface, and a plurality of holes. The anterior surface is configured to reside adjacent a first corneal layer. The posterior surface is configured to reside adjacent a second corneal layer. The plurality of holes extends at least partially between the anterior surface and the posterior surface. The holes of the plurality of holes are configured to substantially eliminate visible diffraction patterns.
