Abstract
The present disclosure provides an intralocular-lens (IOL) or ophthalmic device including an optic and at least one haptic, at least a portion of which is formed from a photoresponsive shape memory polymer network, such as a polydomain azo liquid crystalline polymer network (PD-LCN). The present disclosure further provides systems and methods for adjusting the position of such an IOL or other ophthalmic device using polarized laser radiation.
Claims14
A method of adjusting an intraocular lens (IOL), the method comprising irradiating with polarized laser radiation a portion of a haptic of the IOL comprising a photoresponsive shape memory polymer network to induce a shape change of the haptic and thereby cause the IOL to at least one of translate or rotate in a capsular bag in which the IOL is positioned.
An ophthalmic lens, comprising:
- an optic;
- and
- a plurality of haptics, wherein at least a portion of each haptic of the plurality of haptics comprises a polydomain azo liquid crystalline polymer network (PD-LCN), and wherein each haptic of the plurality of haptics comprises a closed loop attached to the optic.
