A diverging intraocular lens 31 is supported in the eye 1 by a first haptic 34 and a second, opposing haptic 36. The first haptic extends a shorter radial distance from the centre of the lens than does the second, such that the lens is held off—centre from the natural optic axis 50 of the eye. In conjunction with either the natural lens or an anterior prosthetic lens 20, the posterior negative lens shifts the focal point of the eye away from the fovea, which may be damaged through macular degeneration, to an undamaged part 9 of the retina. The lens may be manufactured by lathing the centre of a lens template to form the lens and milling the outer zone of the template to form the haptics. |
