Abstract
This invention relates to the fields of polymer chemistry, materials science and ophthalmology. More particularly it relates to optical components and method(s) of preparing same from hydrophobic acrylic (HA) monomer(s) that exhibit reduced or eliminated glistenings when implanted in a patient's eye. The method of this invention uses a mixture of one or more low temperature initiators (LTI) combined with one or more high temperature initiators (HTI), to polymerize one or more HA monomers to produce an optical HA polymer which, when used to manufacture an optical component and implanted as with an intraocular lens (IOL), exhibit reduced glistenings to the patient.
