Abstract
Systems and methods for high-resolution, wide-angle viewing of a retina of an eye using an ophthalmic microscope that can view a high-resolution image of a retina formed using a wide field of view optical system. A wide field of view optical system can involve a first lens having a diffractive surface on at least one surface and a second lens housing in a shared housing. A wide field of view optical system can involve one or more lens formed from an optical grade polymer and manufactured at a cost that allows the lens to be disposable.
