An apparatus and method for manufacturing intraocular lenses (IOLs) is disclosed. Two mold components (an outer mold component and an inner mold component) of different composition may be employed. The outer mold may be composed of a metal or other refractory material and may serve as the outer die into which a lens forming material can be introduced. The inner mold component may be composed of a softer or more compliant material and may be deployed within the outer mold component. The IOL may be formed by casting the lens-forming material into a shape defined by the space between the two mold components. In certain embodiments, the present disclosure may reduce or eliminate flash in IOLs, improve alignment of their optical surfaces, and/or reduce or eliminate the need for bonded regions.

Apparatus and method of manufacture of intraocular lenses

An intraocular lens includes a deformable outer shell having a distal end and a proximal end, a fluid optic having at least one elastic membrane surface positioned to traverse an optical axis of a patient's eye and at least partially defining an internal chamber to hold an optical fluid, and an inner shell associated with the fluid optic having a distal end and a proximal end. Each end is joined to a corresponding end of the outer shell to define a reservoir between the inner and outer shells, the reservoir at least partially disposed about a circumference of the fluid optic and in fluid communication with the internal chamber. The deformable outer shell is configured to deform upon axial compression of the capsular bag in a manner that increases the volume of the reservoir and draws fluid from the chamber into the reservoir, modifying a curvature of the elastic membrane.

Curvature-changing, accommodative intraocular lenses with expandable peripheral reservoirs

Disclosed herein is an implantable capsule expander device for insertion within a lens capsule of an eye of a patient. The device comprises an arcuate center portion including first and second rims and having a first height, an outermost peripheral portion including a second height that is less than the first height, and a receiving portion formed between the first and second rims. The center portion and the outermost peripheral portion are configured to stabilize the capsule expander device within the lens capsule and to expand the lens capsule. The receiving portion is sized to receive an artificial intraocular lens.

Capsule expander devices, systems, and methods for inhibiting capsular opacification and stabilizing the capsule

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.
