1. A method of making a mask, comprising:
- configuring a body to have an anterior surface capable of residing adjacent a first layer of a cornea of a patient and a posterior surface capable of residing adjacent a second layer of the cornea;
configuring a peripheral portion of the body to be substantially opaque to incident light;
configuring a central portion of the body to be transparent to light incident at the central portion; and
configuring the body with a transport structure capable of substantially maintaining natural flow of at least one biological substance from the first layer to the second layer through the body without producing visible diffraction patterns.

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.
