OPHTHALMIC LENSES HAVING AN EXTENDED DEPTH OF FOCUS FOR IMPROVING INTERMEDIATE VISION
The present disclosure provides an ophthalmic lens (such as an IOL) that is designed to enhance depth of focus for intermediate vision performance, while maintaining distance vision. The lens may include an optic having an anterior surface and a posterior surface disposed about an optical axis. One of the surfaces (e.g., the anterior surface) may have a surface profile involving a superposition of at least three structures or profiles, including a base structure, a phase shift structure having an inner region, an outer region and a transition region, and a zonal structure having an inner power zone and an outer transition zone.
Intraocular lens with extended depth of focus
The invention relates to an intraocular lens with extended depth of focus including aspheric anterior and posterior optical surfaces.
Implantable accomodating intraocular lenses, IOL implants, and related systems and methods
An accommodation-facilitating intraocular implant has: a ring sized to fit within a capsular lens bag of an eye; and a plurality of haptics angularly spaced around and radially extended from the ring. A multi-curve implantable accommodating intraocular lens has a convex anterior and concave posterior.
