Abstract
Abstract Apparatus comprising a spheroidal concave reflector is described for imparting vision to the aphakic eye without the use of a transparent external lens or aperture. A critical radius for the reflector between about 41/2" and 91/2" is defined, and associated apparatus for the convenient illumination and inspection of the eye is described.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
147 words
Apparatus for providing vision to the aphakic eye without the use of either an external aperture or an external transparent lens comprising reflecting means for gathering rays of light from an illuminated portion of the face of a person having an aphakic eye and reflecting same back toward the aphakic eye, said reflecting means positioned a distance from the face of said person appropriate for self examination of the eye and for the insertion, removal, and adjustment of a contact lens, and the curvature of said reflecting means selected in relation to the distance of the image from the reflecting means to cause rays of light emanating from said eye to form, when modified by the combined refraction of the epithelium and cornea and vitreous humor of said eye, an image at the retina of said aphakic eye, whereby said aphakic eye perceives an image of itself.
Claim 2
Dependent Claim
147 words
Apparatus for providing vision to the aphakic eye without the use of either an external aperture or an external transparent lens comprising reflecting means for gathering rays of light from an illuminated portion of the face of a person having an aphakic eye and reflecting same back toward the aphakic eye, said reflecting means positioned a distance from the face of said person appropriate for self examination of the eye and for the insertion, removal, and adjustment of a contact lens, and the curvature of said reflecting means selected in relation to the distance of the image from the reflecting means to cause rays of light emanating from said eye to form, when modified by the combined refraction of the epithelium and cornea and vitreous humor of said eye, an image at the retina of said aphakic eye, whereby said aphakic eye perceives an image of itself.
Claim 3
Dependent Claim
46 words
The apparatus defined in claim 1 further characterized by the general radius of said reflecting means being between about 4.5 inches and 9.5 inches, whereby the distance between said eye and said reflecting means is between about 4" and 12" when the image is in focus.
Claim 4
Dependent Claim
14 words
The apparatus defined in claim 1 further characterized by said reflecting means being spherical.
Claim 5
Dependent Claim
14 words
The apparatus defined in claim 1 further characterized by said reflecting means being parabolic.
Claim 6
Dependent Claim
15 words
The apparatus defined in claim 1 further characterized by said reflecting means is symmetrically spheroidal.
Claim 7
Dependent Claim
42 words
The apparatus defined in claim 2 further characterized by a conventional mirror adapted for inspection of the aphakic eye by a normal eye or by an aphakic eye equipped with an external lens, said conventional mirror positioned adjacent to the reflecting means.
Claim 8
Dependent Claim
57 words
The apparatus defined in claim 2 further characterized by means spaced laterally of said reflecting means for directing diffused light onto said object from a multiplicity of lateral angles permitting illumination of said object without shadows, but without illuminating a hand balancing a contact lens positioned generally over said reflecting means but closer to said reflecting means.
Claim 9
Dependent Claim
28 words
The apparatus defined in claim 7 further characterized by additional means for directing light across said reflecting means to illuminate a contact lens resting on said reflecting means.
Claim 10
Dependent Claim
53 words
The apparatus defined in claim 2 further characterized by means for pivotally mounting said reflecting and an ordinary mirror connected to said reflecting means in back-to-back relation whereby a user may flip the reflecting means over and use the ordinary mirror to inspect the position of a contact lens on the aphakic eye.
