    Abstract: A system for preparing an intraocular lens (IOL) injector for receipt of an IOL. A manifold mates with an injector cartridge and easily distributes a lubricating agent to a load chamber of the cartridge. The IOL is then transferred into the load chamber. The cartridge may be rotatably coupled to the handpiece, and then converted from a preparation and load position to a delivery position. The manifold may remain external to the load chamber or fit within the load chamber and include a handle that remains outside. One or more internal channels in the manifold lead from one or more inlet ports to surfaces in the load chamber than contact the IOL.

    Abstract: A multifocal diffractive lens comprises a multifocal diffractive structure coupled to a refractive component. The refractive component comprises at least one curved surface. The multifocal diffractive structure comprises a first plurality of substantially monofocal echellettes having a first optical power for near vision correction and a second plurality of substantially monofocal echellettes for far vision correction. The first plurality of substantially monofocal echellettes combined with the second plurality of substantially monofocal echellettes can provide a multifocal diffractive profile having decreased light scatter, chromatic aberration, and diffraction to non-viewing orders such that dysphotopsia is substantially inhibited. A third plurality of substantially monofocal echellettes having an intermediate optical power can be combined with the first plurality of substantially monofocal echellettes and the second plurality of substantially monofocal echellettes.

    Abstract: Ophthalmic lenses and methods for their design and use involve displacement functions based on the sum of a continuous cosine function and a continuous sine function, optionally over a plurality of echelettes. Exemplary monofocal and multifocal diffractive ophthalmic lenses provide reduced light scatter and/or improved light energy distribution properties. Such properties can be provided by diffractive profiles, often having subtlety shaped echelettes with appropriately curving profiles. Light scatter may be generated by the sharp corners associated with vertical steps between adjacent conventional diffractive echelettes. Smooth diffractive profiles of the invention reduce light scatter. Light energy directed toward non-viewing diffractive orders may have a unwanted effects on vision quality. Diffractive profiles as described herein may limit the light energy in certain, selected orders, thereby improving viewing quality and mitigating unwanted effects such as dysphotopsia. Diffractive profiles may also vary the light energy distributed between individual echelettes, providing additional advantages in various viewing situations.

    Abstract: An intraocular lens insertion apparatus includes a hollow tube having an interior wall defining a hollow space through which an intraocular lens may be passed from the open space into an eye. A lubricity enhancing component is covalently bonded to the hollow tube at the interior wall in an amount effective to facilitate the passage of the intraocular lens through the hollow space. The lubricity enhancing component includes a substituent component effective to reduce hydrolysis of said lubricity enhancing component relative to an identical lubricity enhancing component without the substituent component.
