Various systems, apparatuses, and processes may be used for performing intraocular lens surgery. In some implementations, a system for intraocular lens surgery may include a first body, a second body, and flexible joint. The first body may be adapted to receive an intraocular lens, and the second body may include a passage adapted to facilitate folding the intraocular lens as the lens is advanced through the passage. The flexible joint may be interposed in a gap between the first body and the second body.
