摘要:
An intraocular lens is disclosed, with an optic (21,28,43,63,82,111,130,200,230)that changes shape in response to a deforming force exerted by the zonules of theeye. A haptic (23,30,42,62,81,112,120,190,220) supports the optic aroundits equator and couples the optic to the capsular bag of the eye. The haptic maybe pre-stressed before the optic is placed within it. After such placement, thepre-stress may be relieved, and the haptic may produce stress in the optic. Thepre-stress may produce a radial tension or a radial compression in the optic.Alternatively, once the optic is placed within the haptic, both may undergo aprocess that changes the size and/or shape of one with respect to the other, causinga stress within the optic. This process may produce a radial tension or a radialcompression in the optic. The haptic may include an annular ring having outerand inner diameters that may depend on the stiffness of the haptic.
