A mask configured to be implanted in a cornea of a patient to increase the depth of focus of the patient includes an anterior surface, a posterior surface, and a plurality of holes. The anterior surface is configured to reside adjacent a first corneal layer. The posterior surface is configured to reside adjacent a second corneal layer. The plurality of holes extends at least partially between the anterior surface and the posterior surface. The holes of the plurality of holes are configured to substantially eliminate visible diffraction patterns.

A posterior chamber phakic intraocular lens comprising a central optical part, a peripheral haptic part comprising a plurality of support elements arranged to lie on a ciliary zonule of an eye, and at least one flexible haptic comprising a reticulated distal region arranged to lay into a ciliary sulcus of the eye.

The invention relates to a lens case (50, 150) for accommodating an intraocular lens, IOL (1). The lens case (50, 150) comprises a lens case body (3, 103) and a sliding element (4, 104) which can slide on the lens case body from a first position to a second position. The lens case body (3, 103) comprises a longitudinal recess (32, 132), having a first part (32a, 132a) and a second part (32b, 132b), the first part (32a, 132a) being adapted to receive a side zone of the IOL (1) comprising at least one haptic (2), the second part (32b, 132b) being adapted to receive a narrower central zone of the IOL (1). The sliding element (4, 104) comprises a bolt (5, 105a) arranged adjacent a loading port (34, 134) of the second part (32b, 132b) of the recess (32, 132) for displacing the IOL (1) within the recess (32, 132).

Provided is an intraocular lens including: an optic portion; and a haptic portion extending from the optic portion, wherein a pattern having ridges and grooves is formed on at least one of the optic portion and the haptic portion, and each of the grooves has a nanostructure roughness. Provided also is a method of manufacturing an intraocular lens, the method including: seating an object to be processed including an optic portion and at least one haptic portion extending from the optic portion, processing a predetermined pattern for guiding cells by performing laser irradiation on the haptic portion and the optic portion, forming grooves having a nanostructure surface roughness in the predetermined pattern formed by laser beams, and the surface of each of the grooves has an average roughness Ra less than 200 nm.

An intraocular lens comprising an optic and four haptics extending from the optic, each haptic having a proximal end meeting with the optic at differing points about a periphery of the optic. The four haptics are arranged into a first pair comprising two arcuate haptics with curvature orientated toward each other such that a distal end of each of the two haptics of the first pair are in nearer relation than their proximal ends; and, a second pair comprising two arcuate haptics with curvature orientated toward each other such that a distal end of each of the two haptics of the second pair are in nearer relation than their proximal end.

The present disclosure provides an intralocular-lens (IOL) or ophthalmic device including an optic and at least one haptic, at least a portion of which is formed from a photoresponsive shape memory polymer network, such as a polydomain azo liquid crystalline polymer network (PD-LCN). The present disclosure further provides systems and methods for adjusting the position of such an IOL or other ophthalmic device using polarized laser radiation.

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. The lens unit includes a lens optics having at least two lens haptics radially outwardly extending therefrom. The base member includes a flat circular base member centerpiece having zero optical power.

An intraocular lens is provided. The intraocular lens includes an optical part and an adjoining haptic part. The optical part includes an optically imaging element and a telescope, the entire telescope being integrally formed and being integrated in the optical imaging element. The optically imaging element has a convexly-curved front side and a concavely-curved rear side. Further, the optically imaging element is arranged as a single lens system.

Ionized radiation-absorbed, dose sensitive, highly flexible polymeric compositions are provided that exhibits multidirectional changes in refractive index. Also provided are methods of producing a precision multi-directional nanogradient of refractive index in a polymeric composition.
