Systems, methods and apparatuses for intraocular imaging system are disclosed comprising an optical coherence tomography (OCT) system. The OCT system has an imaging range that may enable substantial portions of an eye to be imaged. The OCT system may be coupled to an operation microscope, such that, for example, a surgeon can visualize ocular structures like the human crystalline lens and other ocular structures such as the cornea and/or vitreous while surgical instruments are in the field of view.
