Background: Microcannulation, a surgical procedure for the eye that requires drug injection into a 60-90 µm retinal vein, is difficult to perform manually. Robotic assistance has been proposed; however, its effectiveness in comparison to manual operation has not been quantified.
Methods: An eye model has been developed to quantify the performance of manual and robotic microcannulation.
Purpose: To elucidate the merits of robotic application for vitreoretinal maneuver in comparison to conventional manual performance using an in-vitro eye model constructed for the present study.
Methods: Capability to accurately approach the target on the fundus, to stabilize the manipulator tip just above the fundus, and to perceive the contact of the manipulator tip with the fundus were tested. The accuracies were compared between the robotic and manual control, as well as between ophthalmologists and engineering students.

Purpose: Robotics may improve vitreoretinal surgery by steadying hand motion, thereby reducing negative outcomes. This study aimed to develop a microsurgical robot for vitreoretinal surgery and to perform clinical procedures using robot-assisted interventions.
Methods: A microsurgical system for vitreoretinal surgery was designed to meet specific requirements for the degree of freedom, accuracy, and workspace.
Aim: To evaluate the performance of a parallel robotic system by comparison with the conventional manual procedure using an animal model.
Methods: A new parallel robotic system was developed that features a small cylindrical manipulator (base diameter 76 mm, height 240 mm). The performance of the new system was evaluated for its capability to assist in retinal vessel microcannulation.
