发明名称 Intraocular lens
摘要 An improved intraocular lens comprises a plurality of lens segments secured in a flexible and distortable frame member whereby the lens may be temporarily folded for insertion into the eye through a relatively small corneal incision. The preferred lens segments have a thickness of about 1.0 mm or less and comprise an optical material having an index of refraction of 1.5 or more.
