Abstract (en)
[origin: WO2007059160A2] A prosthesis is provided, which includes a positive lens, a negative lens spaced from the positive lens and aligned with the positive lens along an optical axis, and an optic body supporting the positive lens and the negative lens in spaced relation to one another to establish a chamber between the lenses. An optically transmissive primary fluid is contained in the chamber of the optic body. The primary fluid is situated such that orienting the optical axis in a horizontal orientation for far vision positions the optical axis through the primary fluid. An optically transmissive secondary fluid is contained in the chamber of the optic body and is substantially immiscible with the primary fluid. The secondary fluid has a different density and refractive index than the primary fluid. The secondary fluid is situated such that orienting the optical axis for near vision at a range of effective downward angles relative to the horizontal orientation positions the optical axis to extend through the primary fluid and the secondary fluid. Related methods are also provided.
