Abstract
The invention contemplates improved extraocular-lens structures for contact with the cornea of a human eye, to be worn in place of spectacles. The construction features a lens element of requisite prescription power but of diameter which substantially equals or only slightly exceeds the fully dilated pupil size of the wearer, and fenestrated haptic structure engaged to the lens extends radially outwardly and is so thin and axially compliant as to be self-conforming to the curvature of the cornea and to effectively adhere thereto, thus stabilizing the lens for retention of its position on the optical axis of the eye.
Claims33
A contact lens assembly adapted for self-adherent removable mounting to the cornea of an eye, comprising a circular lens element, and haptic means peripherally engaging and mounting said lens element, said haptic means being of sheet material including integrally formed axially compliant radially outward foot formations extending outward of said lens element at angularly spaced locations, said foot formations being substantially fenestrated and being of such compliant action as to bendably deform in continuous smooth conformance to the surface curvature of the cornea and to adhere thereto solely through contact with natural moisture of the surface of the cornea.
