Purpose. To evaluate the structural and clinical advantages of our new remote control micro-injector for current critical vitreoretinal procedurefPAT. P). Methods. We manufactured the remote control injector for trial. Components were disposable syringes as slave actuator(5 ml) and as master controller.5 or 1 ml), clean water and plastic extension tube for pressure transmission, and paper clips to connect the syringes. This injector was used for viscodelamination and subretinal t PA injection in vitrectomy. Results. The following advantages were confirmed through the operations: stability of needle tip, no operative view blockade, hydraulic reduction effect(Pascal's law), minimal dead space, low cost, simple design for less mechanical trouble, sophisticated man-machine interface, easy operation, and power source free. Conclusions. This study shows the utility of our new instrument in ocular surgery.
