Abstract
A silicone oil having a mean molecular weight average greater than about 20,000 Daltons, with no more than about 3% to about 4% of the total silicone oil by weight being comprised of components having a molecular weight less than about 15,000 Daltons. In some embodiments, the silicone oil is used in intraocular lens devices.
