Abstract: A method improves depth of focus in a first eye only by adding a higher order aberration (HOA) to the first eye by adding a monofocal optical device to the first eye. The method may also correct a spherical aberration in a second eye by inserting a monofocal aspheric IOL. The HOA added to the first eye may be selected from the group consisting of spherical, trefoil and coma. Additionally, the monofocal optical device inserted into the first eye may comprise a monofocal aspheric IOL that adds spherical aberration to the first eye. The optical device inserted into the first eye may comprise a 20 D monofocal aspheric IOL that adds 0.4 ?m of spherical aberration to the first eye at 6 mm entrance pupil and adds 0.1 ?m of spherical aberration to the first eye at 4 mm entrance pupil.

Abstract: Hybrid Accommodating Intra Ocular Lens (AIOL) assemblages including two discrete component parts in the form of a discrete base member for initial implantation in a vacated capsular bag and a discrete lens unit for subsequent implantation in the vacated capsular bag for anchoring to the discrete base member.

Abstract: The invention relates to a multifocal lens (1) with a refractive focus (Fr) and with a diffractive structure (5) which, in the radial direction (r) of the lens (1), plotted across the squared radius (r2), has a periodic profile (6, 7, 8, 9), wherein the profile (6, 7, 8, 9) per period has four adjoining portions (6, 7, 8, 9) which are not differentiable at their connection sites (10, 11, 12, 13), wherein a first portion (9) has a monotonically falling function and the three further portions (6, 7, 8) have a monotonically rising function or vice versa, and wherein the further portion (7), which does not adjoin the first portion (9), has a greater pitch than the other further portions (6, 8).

Abstract: An intraocular lens comprises an optic and two or more haptics, wherein the optic is convexo-concave, i.e. both faces are curved in the same sense with respect to the plane defined by the rim of the optic, wherein the haptics lie at an angle with respect to said plane and on the same side thereof as the optic's faces, and wherein each haptic has a smooth, undulating radially outer edge.

Abstract: A cartridge for storing and implanting an intraocular lens has a first part and a second part that are movable relative to one another from a storage configuration, in which interior surfaces of the first and second portions define a storage chamber for storing the IOL in an unfolded state, to an implanting configuration, in which the interior surfaces of the first and second portions together define a smooth-bored implanting chamber for retaining the IOL in a folded state. According to a first aspect, the first and second portions are hinged together, whereas according to a second aspect, the first and second portions are slidably interconnected.

Abstract: An intraocular lens comprises an optic and one or more haptics, wherein the or each haptic can be compressed in the plane of the lens, and which additionally comprises, around the optic, an annular rim that, in use, is in contact with the posterior capsular sac.

Abstract: An intraocular lens is described which comprises, as one face thereof, a linear Fresnel prism array with facets angled relative to the optical axis of the lens so as to deviate light incident thereon to an off-axis position. The facets are modified so as to reduce at least one of diffraction effects and astigmatism associated with the Fresnel prism. In particular, by varying the pitch of the prism elements across the array, which may comprise varying their size, a diffraction grating effect can be reduced or negated, such that light is not diffracted into undesirable orders and multiple images can be avoided. Furthermore, chromatic angular dispersion associated with the diffraction grating effect may be reduced. The pitch variation can be random. By varying the angle of the facets across the array, astigmatism that would otherwise result from the presence of the Fresnel prism can also be compensated.
