SYSTEM AND METHOD FOR INCREASING THE DEPTH FOCUS OF THE HUMAN EYE
First Claim
1. A method for screening a patient for an ophthalmic mask, the method comprising:
- providing an assembly comprising a posterior surface, an anterior surface opposite the posterior surface, and a mask defining an aperture and configured to increase the patient'"'"'s depth of focus, the mask being located between the posterior and the anterior surfaces;
placing the assembly on a cornea of a first eye of the patient such that the posterior surface of the assembly substantially conforms to an anterior surface of the cornea; and
testing the patient'"'"'s vision in the first eye.

Abstract
A method and apparatus for increasing the depth of focus of the human eye is comprised of a lens body, an optic in the lens body configured to produce light interference, and a pinhole-like optical aperture substantially in the center of the optic. The optic may be configured to produce light scattering or composed of a light reflective material. Alternatively, the optic may increase the depth of focus via a combination of light interference, light scattering, light reflection and/or light absorption. The optic may also be configured as a series of concentric circles, a weave, a pattern of particles, or a pattern of curvatures. One method involves screening a patient for an ophthalmic lens using a pinhole screening device in the lens to increase the patient'"'"'s depth of focus. Another method comprises surgically implanting a mask in the patient'"'"'s eye to increase the depth of focus.

27. A method for screening a patient for an ophthalmic lens configured to increase depth of focus, the method comprising:
-
fitting each of the patient'"'"'s eyes with a first contact lens; placing a mask configured to increase depth of focus on each of the first contact lenses; fitting each of the patient'"'"'s eyes with a second contact lens, the second contact lens being placed over the mask to hold the mask in a substantially constant position; and testing the patient'"'"'s vision. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)
