Vitrectomy is one of the ophthalmic surgeries that require a large number of instruments. Despite a growing array of single-use disposable instruments, vitrectomies for refractory diseases still involve complicated procedures and many surgical devices. As to the arrangement of materials and instruments on the surgical table, fluids that must not be introduced intraocularly, infusion fluid for washing the ocular surface, fluids for intraocular injection, and fluids for periocular injection are classified and marked to avoid using the wrong fluid. Since bacteria are present in the fluid retained in the fluid catch bag, the accumulated infusion fluid should be removed by aspiration.
