Abstract: An accommodating intraocular lens includes an optic and four haptics. the optic includes an outer wall, a solid posterior optic, an anterior fluid chamber, an anterior membrane and a fluid reservoir within the outer wall surrounding the anterior fluid chamber and the solid posterior optics. The four haptics are attached to the outer wall at four attachment points. Each of the four haptics includes an arc member extending between successive attachment points and contacting the outer wall only at the attachment points. Each of the arc members is configured to compress laterally under accommodative forces.

Abstract: An accommodating intraocular lens includes a haptic assembly and a flexible optic. The haptic assembly includes an anterior ring, a posterior ring, anterior spring arms, and posterior spring arms, wherein the anterior spring arms and the posterior spring arms bias the anterior ring and the posterior ring apart from one another. The flexible optic is suspended between the anterior ring and the posterior ring and connected to the haptic assembly by a plurality of support struts. The support struts are adapted to deform the flexible optic upon axial compression of the haptic assembly so that an optical power of the flexible optic is reduced relative to an uncompressed state of the haptic assembly.

Abstract: A cartridge includes a body, a reservoir, a filter, and a tab. The body is configured to be held in a fixed relationship relative to a stem, wherein the body comprises an inlet and an outlet. The inlet is configured to receive a fluid from a surgical instrument via the stem. The outlet is configured to output a first portion of the fluid from the cartridge. The reservoir is configured to receive the fluid from the inlet. The filter is configured to filter the first portion of the fluid as the first portion of the fluid is directed from the inlet, through the filter, and to the outlet. The tab connected to the body and configured to engage with the stem. The tab is configured to, when the cartridge is moved to disengage from the stem, at least one of break away from the body and become functionally inoperable.

Abstract: A curvature changing accommodative intraocular lens is provided in which the anterior surface of the intraocular lens undergoes dynamic change in curvature to focus light from distant objects to those nearby. The lens utilizes fluid movement from bladders defined as junctions between haptic elements and lens element or bladders positioned between the haptic elements and lens element periphery to change the curvature.

Abstract: An accommodative intraocular lens is described that provides monofocal vision at multiple pre-defined focal points during accommodation. The intraocular lens includes a lens element having a series of stacked optics that can be formed utilizing multiple different materials, each of which can have a different stiffness. In an implanted, disaccommodated state, the lens element can have a pre-defined curvature to thus define a first or base focal point of the intraocular lens. Upon accommodation of the patient's eye, the optics can be compressed and/or deformed at differing intervals so as to provide the intraocular lens with three or more distinct focal points. As an alternative, the lens element can include optics formed with multiple sets of haptic elements having varying haptic stiffnesses to vary compression of the optics in order to provide the intraocular lens with multiple focal points.

Abstract: A lubrication cartridge includes a cartridge body. A cartridge coupling is located on the cartridge body and defines a first passage and a second passage. A lubricant reservoir is housed in the cartridge body and comprises a pressurized fluid inlet coupled to the first passage and a lubricant outlet coupled to the second passage. A metering insert is located between the lubricant outlet and the second passage and comprises a density that controls lubricant flow between the lubricant reservoir and the second passage.

Abstract: An accommodative intraocular lens (IOL) system is disclosed for insertion into an eye to provide accommodative vision, the system including a first lens having an first optic, a second lens having a second optic, a transparent, low refractive index medium disposed between the first and second optics; and at least one haptic connected to the first and second lenses and configured to facilitate movement of one lens relative to the other lens, such that when the lens system is positioned in an eye, ciliary muscle movements can alter the distance between the first and second lenses and vary the overall lens power of the system.
