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.
