An intraocular lens system comprising at least one intraocular lens having an anterior surface and a posterior surface, wherein at least one surface of the lens is aspherical to provide for a continuum of retinal images to be focused at the retina in an area between two retinal eccentricities. The system may include an anterior light-converging intraocular lens 16 for positioning within the eye, the anterior lens having an anterior surface and a posterior surface; and a posterior light-diverging intraocular lens 17 for positioning within the eye posterior to the anterior lens, the posterior lens having an anterior surface and a posterior surface; wherein one or both surfaces of the anterior lens and/or one or both surfaces of the posterior lens are aspherical.

Fluidic glasses for correcting refractive errors of a human or animal are disclosed herein. The fluidic glasses includes at least one flexible fluidic lens having an outer housing and a flexible membrane supported within the outer housing, the flexible membrane at least partially defining a chamber that receives a fluid therein; and a fluid control system operatively coupled to the at least one flexible fluidic lens, the fluid control system configured to insert an amount of the fluid into the chamber of the at least one flexible fluidic lens, or remove an amount of the fluid from the chamber of the at least one flexible fluidic lens, in order to change the shape of the at least one flexible fluidic lens in accordance with the amount of fluid therein, thereby correcting the refractive errors of an eye of a human or animal.

A slit lamp and biomicroscope assembly can include a viewing system including a biomicroscope; an illumination system including a slit lamp with a light source and a light processing system with a first actuator; a positioning system supporting the biomicroscope and the slit lamp and including second and third actuators to position the biomicroscope along horizontal and vertical axes; and a user interface handle. The user interface handle can be graspable by a hand of a user and supported on the positioning system proximate to the biomicroscope such that a user looking into the biomicroscope can reach the user interface handle. The user interface handle can include a plurality of input devices including input devices in communication with the actuators.

An accommodating intraocular lens assembly can include a first lens, a first stanchion, a second lens, and a second stanchion. The first lens can have a first anterior side and a first posterior side. The first stanchion can have a first distal end connected to the first lens and a first base end. The second lens can have a second anterior side and a second posterior side. The second stanchion can have a second distal end connected to the second lens and a second base end. The first lens and the second lens can move laterally relative to one another during contraction of the ciliary muscle in a vertically-extending plane containing the optic axis of the eye and substantially centered in the eye.

A trephination apparatus can include a first member, a blade, and a second member. The first member can include a through-aperture and a first internal chamber. The first member can also include opening to the first internal chamber that can surround the through-aperture in a plane. The blade can have an outwardly-facing male profile at least partially matching the through-aperture and have a cutting edge. The second member can include a first body sized to be received in the through-aperture with the blade. The blade can be positionable between the first body and the female profile at the second opening. The second member can also include a second internal chamber with an opening extending about the aperture axis in the plane with an opening to the first internal chamber.
