An intra ocular lens (IOL) for placement in the capsular bag and securing the IOL in an opening in an anterior part of a capsular bag, with an anterior capsular bag flap surrounding said opening. An anterior side, which in use when the IOL is implanted in an eye is directed towards a cornea of the eye. A posterior side, which in use when the IOL is implanted in an eye is directed towards a retina of the eye. The IOL comprises an optical structure, at least two posterior supports to provide support for a posterior surface of an anterior capsular bag flap, and at least two anterior supports to provide support for an anterior surface of an anterior capsular bag flap, when IOL residing inside and outside of the anterior capsular bag flap respectively.

Methods of manufacturing an optic of an accommodating intraocular lens to have an aspheric lens surface, including providing an optic comprising an anterior element and a posterior element that at least partially define an optic fluid chamber, wherein at least one of the anterior element and the posterior element has an external surface that is spherical; and prior to inserting the accommodating intraocular lens into an eye, changing the shape of the at least one of the anterior element and the posterior element from the spherical configuration to an aspherical configuration.

The invention provides an intra ocular lens structure (IOL) for placement in the capsular bag and securing the IOL in an opening in an anterior part of a capsular bag, with an anterior capsular bag flap surrounding said opening, said IOL having an anterior side which in use when the IOL is implanted in an eye is directed towards a cornea of the eye, and a posterior side which in use when the IOL is implanted in an eye is directed towards a retina of the eye, said IOL comprising an optical structure, at least two posterior supports for when the IOL is implanted in the capsular bag residing in the capsular bag extending away from said optical structure, said posterior supports adapted for in use providing support surfaces for a posterior surface of an anterior capsular bag flap, and at least two anterior supports for when the IOL is implanted in the capsular bag residing outside the capsular bag extending away from said optical structure, said anterior supports adapted for in use providing support surfaces for an anterior surface of an anterior capsular bag flap.

Accommodating intraocular lenses containing a flowable media and their methods of accommodation.

An intraocular lens, comprising an optic having an anterior surface and a posterior surface, providing a refractive base power, at least one of the anterior surface and the posterior surface having disposed thereon a profile comprising steps having heights determined by combining three constituent diffractive profiles. The diffractive profiles correspond to powers p1, p2 and p3, the powers being different than one another and each power being a positive power less than about 1D or about 1.25D. Each of the diffractive profiles having step heights causing a phase delay, relative to aqueous fluid, of 0.6 to 1.2 times 2 for 546 nm light. The combined profile defined by the function: z=max (diffractive profile (p1), diffractive profile (p2), diffractive profile (p3)), where p3>p2>p1.

A prosthetic capsular device configured to be inserted in an eye after removal of a lens, in some embodiments, can comprise a housing structure comprising capable of containing an intraocular device and an equiconvex refractive surface. The housing structure can comprise an anterior portion comprising an anterior opening, a posterior portion comprising a posterior opening, and a continuous lateral portion between the anterior portion and the posterior portion.

Generally, an intraocular implant having on the external surface a plurality of pattern surface elements disposed in spaced apart relation defining a tortuous pathway adapted to control a flow of fluid, or a flow of particles suspended in a fluid, or inhibits the growth or migration of cells. In particular, an intraocular implant which implanted between an intraocular lens and the surface of the posterior capsule of the eye inhibits growth or migration of residual lens epithelial cells after cataract surgery by providing structural barriers to reduce posterior capsule opacification of the eye.

The invention provides an intra ocular lens assembly comprising an intra ocular lens structure (IOL) for placement in the capsular bag and securing the IOL in an opening in an anterior part of a capsular bag, with an anterior capsular bag flap surrounding said opening, and a secondary intraocular lens (S-IOL) comprising fixing parts for attaching said S-IOL to said IOL.

An open, seal-less intraocular lens is disclosed herein. An example intraocular lens may include an annular substrate including an oil electrode disposed in or on an inner sidewall of the annular substrate to electrostatically manipulate a volume of electrowetting oil, an optical window coupled to the substrate, where a side of the optical window adjacent to the inner sidewall and the inner sidewall of the annular substrate define a region for constraining the volume of electrowetting oil, and a saline electrode coupled to the annular substrate, the saline electrode positionable within an aqueous humor of an eye upon implantation

An ophthalmic device having posterior and anterior features are disclosed herein. An example ophthalmic device may include an enclosure having an insert disposed therein. The enclosure may include a cornea contact disposed on a posterior side and arranged to rest on a user's cornea outside of a central cornea area when the ophthalmic device is worn by a user. The enclosure further includes a channel formed in the posterior side, where the channel extends through the cornea contact from at least radially outside of the insert to an inner edge of the cornea contact, and a fenestration formed there through, wherein the fenestration is arranged radially outside of the insert and formed to intersect with a proximate end of the channel.
