To kill crystalline lens epithelial cells remaining in a crystalline capsule at a surgery for cataract.
A plug 1 seals an incision opening formed at anterior capsulotomy from the inside of a crystalline capsule. The plug 1 comprises: a convex part 2 which protrudes to a hydatoid side rather than to the incision opening when sealing is made; and a flange part 3 made to be larger than the incision opening. The plug further comprises: a conduit line 4 for infusion to infuse a hypotonic solution or an isotonic solution into the crystalline capsule from the outside in order to kill crystalline lens epithelial cells remaining in an anterior capsule by infusing the hypotonic solution or the isotonic solution into the crystalline capsule; and a conduit line 5 for suction to suck, to the outside of the crystalline capsule, the hypotonic solution or the isotonic solution infused into the crystalline capsule. This ensures that the crystalline lens epithelial cells do not grow after the surgery for cataract, preventing cataract from appearing later. When an adjustment-type intraocular lens is used, the focus adjustment function is preserved in a good condition.
