Intraocular lenses with shape-changing optics

An intraocular lens (IOL) having an optical axis extending in an anterior-posterior direction and an equator extending in a plane substantially perpendicular to the optical axis, the IOL comprising:

• an elastic anterior face located anterior to the equator;
• a posterior face located posterior to the equator, wherein the anterior face, the posterior face, or both comprises a poly(dimethylsiloxane) elastomer having a durometer between about 30 Shore A to about 50 Shore A;
• and
• a chamber located between the anterior face and the posterior face and comprising a silicone oil comprising polysiloxanes comprising diphenyl siloxane and dimethyl siloxane units, the silicone oil having a maximum viscosity of about 700 mm2/s at 25° C. and having a mean molecular weight of less than about 3000 Daltons.
