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.
Claims18
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;
- and
- a plurality of nutrient flow paths extending between the anterior surface and the posterior surface;
- wherein at least one of the nutrient flow paths is configured to substantially prevent propagation of light therethrough from the anterior surface to the posterior surface to reduce diffraction patterns visible to the patient.
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 transmit along an optical axis incident light in the central portion;
- and
- configuring the body with a transport structure capable of substantially maintaining natural nutrient flow from the first layer to the second layer, the transport structure substantially preventing propagation of light therethrough from the anterior surface to the posterior surface to reduce visible diffraction patterns.
