Claim:
An intraocular surgical apparatus comprising: a main body that can be held in a surgeon's hand, the main body further comprising: a pulverizing member that is attached at one end of the main body and that pulverizes a predetermined affected tissue; an inlet channel that supplies perfusate to the vicinity of the pulverizing member; an aspiration channel for aspirating the affected tissue that has been pulverized by the pulverizing member; and a decompression-compensating instrument that is for use in intraocular surgery and is connected to a point midway along the inlet channel, the decompression-compensating instrument comnrising: a storage member, having a capacity of 7 cm 3 to 22 cm 3 , connectable to a point midway along the supply channel, wherein the storage member forms a chamber that is closable except for an opening from which the perfusate that is to be supplied to the supply channel flows; the decompression-compensating instrument supplies the perfusate into the affected part when the internal pressure of the affected part is excessively lowered, the perfusate being supplied from the storage member, whereby a rapid decrease in an inflow rate thereafter is prevented.
