An intraocular lens for correcting of refraction, includes at least one optical lens with an optical axis; and haptics, connected to the optical lens, for positioning the lens in front of the capsular bag of an eye, for example arranged to be placed in the sulcus of the eye; wherein haptics include at least one ring shaped flexible arm, preferably at least a pair of ring shaped flexible arms arranged on opposite sides of the optical lens, preferably as seen perpendicular to the optical axis. The optical lens includes an optical power element for correcting the refractive power of an eye. The optical lens further includes a multifocal optical surface for extending the depth of field of an eye.

An accommodating intraocular lens construction includes a lens of fixed optical power to correct refractive error and a lens of variable power to restore accommodation of the eye, which variable lens can have two optical elements which either shift perpendicular to the optical axis, or which variable lens can have two elements which move along the optical axis. The accommodating intraocular lens has at least one haptic to provide transfer of movement to at least one of the optical elements and at least one additional haptic for sulcus fixation to provide limitation of movement of at least one component of the lens along the optical axis. The movement of the additional haptic is largely independent from the haptic for movement.

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.

An accommodating intraocular lens for providing a range of accommodative vision contains an optic and a haptic. The optic is disposed about an optical axis and includes an anterior surface and a posterior surface defining a clear aperture of the optic. The haptic is at least partially disposed inside the optic and includes an inner structure, an outer structure, and a plurality of arms disposed between and connecting the inner structure and the outer structure. The inner structure is circumferentially disposed about the optical axis, while the outer structure is circumferentially disposed about the inner structure and has an outer face. Each arm has proximal portion adjacent the inner structure and a distal portion adjacent the outer structure that is bifurcated in a radial direction from the proximal portion. The intraocular lens also has an outer surface defined by outer surfaces of the plurality of arms and an outer surface of the outer structure. The inner structure and at least a portion of the arms are disposed inside the clear aperture. The distal portion of each arm has a larger axial extent than an axial extent of the inner portion. The distal portion of each arm has a larger axial extent along the outer surface than an axial extent of the outer structure along the outer surface.

The invention relates to an artificial intra ocular lens of variable optical power, comprising at least two optical elements which can be shifted relative to each other in a direction extending perpendicular to the optical axis wherein the optical elements have such a shape that they exhibit, in combination, different optical powers at different relative positions. This results in a construction which has such a low weight that it is applicable as an intra ocular lens of adjustable optical power. According to a first preferred embodiment the lens comprises positioning means the optical elements in the eye and driving means, which can be operated by the user to execute a movement of at least one of the optical elements relative to the other optical element. This embodiment can be used to correct the accommodation function.

The invention relates to a lens which has an extended range of focus, wherein the lens consists of a solid material, the optical surfaces of the lens are transparent and the lens has a focal power distribution. According to the invention, the focal power distribution F.sub.G of the lens (1), in relation to a plane perpendicular to the optical axis (10), changes as a function of the radial height r and of the azimuth angle phi of the aperture between a base value of the focal power F.sub.L not equal to zero and a maximum value F.sub.Smax. Hence, the focal power distribution emerges as
F.sub.G(r,phi)=F.sub.L+F.sub.S(r,phi),
with the spiral focal power component
F.sub.S(r,phi)=F.sub.Smax(r)*w(phi),
where F.sub.Smax(r) depends nonlinearly on the radius and w(phi) is a factor for the focal power component with a spiral profile.

A novel lens for variable focus has two optical elements which simultaneously move in a lateral and an axial direction. The lens also includes variable corrective optics to correct for undesired variable optical aberrations. The lens can be used as an accommodating lens for implantation in the capsular bag. The lens can be driven by either the surfaces of the capsular bag as well as the rim of the capsular bag.
