  • Methods and systems for cataract surgery using intraocular illumination
    Patent number: 11826282
    Abstract: A method for cataract surgery includes incising a continuous curvilinear capsulorrhexis (CCC) in an anterior capsule of a lens of an eye, inserting an endoillumination probe into the lens through the CCC, further inserting the endoillumination probe to a location below an equator of the lens and below a nucleus of the lens, tilting the endoillumination probe to laterally aim light emitted from the endoillumination probe behind the nucleus, and chopping the nucleus with a chopper needle of the endoillumination probe. The chopping further includes chopping the nucleus with a phaco tip.
