Abstract
The disclosure relates to an intraocular lens having an optic body and a haptic element including a thermoresponsive polymer having a transition temperature and particles that are magnetic and/or magnetizable. The disclosure additionally relates to a treatment apparatus including the intraocular lens and a magnet set up to subject the intraocular lens to a magnetic field that alternates with time.
Claims19
An intraocular lens, comprising:
- an optic body;
- and
- a haptic element including a thermoresponsive polymer having a transition temperature and particles that are magnetic and/or magnetizable,
- wherein the thermoresponsive polymer forms the surface of the haptic element at least in part of a region of the haptic element and is set up such that a chemical bond of the thermoresponsive polymer breaks on exceedance of the transition temperature.
1 more element
An intraocular lens, comprising:
- a first thermoresponsive polymer which forms a surface of a haptic element at least in that part of a region of the haptic element;
- and
- a second thermoresponsive polymer which has a glass transition temperature or a melting temperature and is set up to irreversibly change the shape of the haptic element on exceedance of the transition temperature.
