Abstract: A multifocal IOL including at least one diffractive surface including a plurality of discrete, adjacent, diffractive, concentric rings, having a radial phase profile cross-section with a near-symmetrical diffractive surface topography, and an odd number, greater than three, of diffractive orders and an asymmetrical distribution of energy flux over the diffractive orders.

Abstract: An intraocular assembly includes a peripheral side wall (12) that has a rim (16) sized to receive therein an intraocular device, and a posterior peripheral edge (20) that is sharp and extends out from a posteriorly-facing end face (22) of the side wall. An interior perimeter of the rim is a combination of continuous concave and convex shapes.

Abstract: An intraocular clip including first and second hook members extending generally coplanarly in opposite directions from a spine, the spine being formed with an attachment member attachable to ocular structure.

Abstract: A packaging system for an IOL including an IOL pre-packaged in a liquid medium in a load chamber of an IOL delivery device, the IOL delivery device including an injection port through which the IOL is expellable.

Abstract: A multifocal contact lens having a posterior surface and an anterior surface, includes a distance vision segment and a near vision segment, and at least one hole through which the posterior surface and the anterior surface communicate with each other.

Abstract: A multifocal contact lens, having a rear surface configured to float on a tear film covering the user's cornea, a front surface comprised of at least two contiguous surface segments, an upper surface segment optically configured to serve for distance vision and a lower surface segment optically configured to serve for near vision. In at least one peripheral zone of the lens there is provided at least one recess constituting a preferred escape aperture for parts of the tear film displaced when the contact lens slides down the user's cornea, to the effect of substantially preventing rotation of the contact tens during lens translation.

Abstract: A contact lens having a back surface comprising a central zone and at least one marginal zone. The central zone and the marginal zone being each constituted by portions of second-order surfaces of revolution other than spherical. The transition from the central to the marginal zone is tangential, and in the marginal zone, the axial clearance between the cornea and the back surface increases in direction towards the edge of the lens.
