There is provided an intraocular lens including an optic portion having a circular shape from one side thereof and including a first pattern which includes a ridge and a groove, and a plurality of haptic portions extending from an outer circumferential edge of the optic portion and each including a second pattern which includes a ridge and a groove, in which at least one of the ridges included in the first pattern and the second pattern and at least one of the grooves included in the first pattern and the second pattern includes a section in which a width is formed differently.

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.

An accommodating intraocular lens (AIOL) for implantation within a capsular bag of a patient's eye comprises first and second components coupled together to define an inner fluid chamber and an outer fluid reservoir. The inner region of the AIOL provides optical power with one or more of the shaped fluid within the inner fluid chamber or the shape of the first or second components. The fluid reservoir comprises a bellows region with fold(s) extending circumferentially around an optical axis of the eye. The bellows engages the lens capsule, and a compliant fold region between inner and outer bellows portions allows the profile of the AIOL to deflect when the eye accommodates for near vision. Fluid transfers between the inner fluid chamber and the outer fluid reservoir to provide optical power changes. A third lens component coupled to the first or second component provides additional optical power.

An improved self-centering phakic refractive lens is disclosed. The lens floats freely in the posterior chamber of the eye and corrects vision of the patient but also prevents buildup of intraocular pressure, cataract induction and iris pigment dispersion. The lens comprises an optical body, haptic members which extend outward from the optical body, and a small hole in the approximate center of the optical body for the purpose of allowing aqueous humor to flow through that hole. The lens is designed such that its posterior surface conforms to the shape of the anterior surface of the patient's natural crystalline lens.

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.

An illustrative method of treating a patient having an eye condition includes determining that the patient has a closed-angle or narrow-angle glaucoma. The method further includes treating the closed-angle or narrow-angle glaucoma during a surgical procedure performed on the patient. The method further includes, during the surgical procedure, treating the patient with an excimer laser to create a plurality of perforations in the trabecular meshwork by applying a plurality of shots to the trabecular meshwork from the excimer laser.

An intraocular lens (IOL) for implantation within a capsular bag of a patient's eye comprises an optical structure and a haptic structure. The optical structure comprises a planar member, a plano convex member, and a fluid optical element defined between the planar member and the plano convex member. The fluid optical element has an optical power. The haptic structure couples the planar member and the plano convex member together at a peripheral portion of the optical structure. The haptic structure comprises a fluid reservoir in fluid communication with the fluid optical element and a peripheral structure for interfacing to the lens capsule. Shape changes of the lens capsule cause one or more of volume or shape changes to the fluid optical element in correspondence to deformations in the planar member to modify the optical power of the fluid optical element.

An intraocular lens has an upper surface and a lower surface, and comprising an optic portion, and at least one haptic portion connected to the optic portion and extending outward from the optic portion, and a channel disposed in the intraocular lens and having a first end being disposed in the optic portion and a second end disposed in the haptic portion. The channel extends generally radially outward from the optic portion into the haptic portion and is generally linear in a radial direction, but can have some curvature if desired. The channel is open to a top surface of the optic portion and haptic portion along the length of the channel or is disposed below the top surface of the optic portion and haptic portion, with openings in the top surface of the optic portion and haptic portion on each end of the channel.
