Patients and Methods
Institutional review board approval to review patient data was obtained for this study, all patients signed an informed consent form before intervention, and all data were collected in accordance with compliance guidelines outlined by the Health Insurance Portability and Accountability Act of 1996.
We retrospectively reviewed a consecutive series of 140 nonvitrectomized eyes of 140 patients who underwent 25-gauge transconjunctival posterior segment surgical procedures performed by 5 surgeons
Results
Overall results are summarized in Table 1. Overall, 71 men and 69 women, with a median age of 67 years (mean, 67.1±13.7 [standard deviation]), were observed for a mean of 33.8±9.7 weeks. Minimum follow-up time was 12 weeks. Median preoperative VA was 20/250 (logMAR, 1.08±0.47), and median postoperative VA at final visit was 20/60 (0.47±0.3) (P<0.0001) (Fig 1). Mean preoperative IOP was 16.3±4.1 mmHg, and mean postoperative IOPs at 1 day, 1 week, and final visit were 15.9±6.2 (P = 0.46),
Discussion
Minimally invasive vitreoretinal surgery has been proposed in the past by other authors.6, 7, 8, 9, 10, 11 Chen12 proposed sutureless tunnel-based sclerotomies, but his series revealed difficulty in passage of conventional instrumentation along with several complications, including wound extension, dehiscence, and leakage; vitreous and/or retinal incarceration; hemorrhage; retinal tears; and dialysis.6, 9, 12 Also, although these were touted to be minimally invasive, conjunctival dissection and

Novel force sensing module for a concentric tube-based vitreoretinal surgical robot
2020, Sensors and Actuators, A: PhysicalCitation Excerpt :The overall shape varies according to the interaction force between the tubes when relative rotation and translation occur [10]. Because the pivoting motion of conventional straight tools may cause additional stress on the sclera and occasionally results in ocular hypotony [11], our research group proposed that the CTR with its capability of bendable motion within the eyeball (as illustrated in Fig. 1) can be a good solution for minimizing scleral stress and increasing the accessible workspace while minimizing the potential risk of touching delicate tissue in the eyeball [12]. CTR has attracted significant attention from researchers owing to its dexterity and convenient miniaturization [13].
