Abstract
An intraocular surgical apparatus including an introduction tube for introducing perfusate into a closed intraocular affected part, a discharge tube for discharging the affected part and the perfusate, a perfusate feed passage connected to the introduction tube and incorporating a perfusate reservoir for feeding the perfusate with a predetermined rest liquid head pressure, a valve for controlling the amount of perfusate fed from the reservoir to the introduction tube, and a discharge passage connected to the discharge tube and incorporating a suction pump. The perfusate feed passage further incorporates, at a passage portion thereof from the control valve to an outlet opening of the introduction tube, a pressure-reduction compensating means for feeding supplementary perfusate into the closed intraocular affected part through a supplementing passage having a smaller passage resistance than the perfusate feed passage in the event of and in association with abnormal pressure reduction inside the affected part.
