ABSTRACT:
The invention contemplates haptic construction for support of a finished intraocular lens element, wherein the haptic has plural radially outward stabilizing-leg formations, which incorporate a feature of radial adaptability in terms of the anterior-chamber wall size to which the lens may be fitted. Various embodiments are described to illustrate application to a single-piece and to multiple-piece haptics, and to illustrate radially compliant yieldability as well as ratchet-retention of a selected radial span of the stabilizing leg formations.
