Mask configured to maintain nutrient transport without producing visible diffraction patterns

A mask (4200) 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 (4220). The anterior surface is configured to reside adjacent a first corneal layer. The posterior surface is co...

Beschreibung
Zusammenfassung:	A mask (4200) 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 (4220). 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.
