“…Limitations of this system that came into knowledge were the presence of a high remote center of motion (RCM) in the robot, which is located directly on the wrist and a great distance from the head of the device. This leads to unnecessary stress and the need for another RCM in the process at the site of penetration [6].…”

“…These limitations make humans insufficient and thus come to light the robots with integrated imaging modalities such as digital microscopy and optical coherence tomography (OCT). Procedures such as maintaining cannulation and inserting a retinal vein cannula with successful infusion are technically beyond the scope of the majority of surgeons [ 6 ]. In addition, the challenges faced by surgeons in determining the optimal timing of a procedure, and the optimal drug for administration, collectively limit the feasibility of the procedure.…”

In this paper, an overview of the integration of robotic techniques into surgical fields of ophthalmology is described and the details about the latest advancements and future potentials associated with it are presented.The eye is a small, enclosed space that does not tolerate the misplacement of instruments that general surgery can tolerate. As the retina doesn't regenerate, it is of paramount importance to avoid injury. Furthermore, there are additional limitations of unassisted human hands in terms of dexterity, tremor, and precision in positioning instruments in the eye. Robotics has become a promising solution to these human challenges. The emergence of robotic technology into the domain of rapidly advancing micro-invasive surgery has reduced discomfort in patients and enhanced safety, capabilities, and outcomes. With the arrival of the Femtosecond laser system for robotic cataract surgery in several hospitals in India, the paradigm of robotic surgery has shifted as people started to accept and apply it. Although there is still much to learn in this area, there is growing interest in creating gadgets that perform complete surgical procedures. The fundamental objective of these surgeries would be to increase speed and efficiency without compromising the capacity to increase precision. Major criteria include an acceptable range of motion, the capacity to switch instruments mid-surgery, and simultaneous manipulation of the surgical instrument.Robotic surgery is an already well-established technological advancement employed across the globe by leading surgeons in their fields but its curve in ophthalmology is still under supervision. Just like every other advance, robotics has its own set of disadvantages including but not limited to the costs, limited availability, and long learning curve. Nonetheless, this paper doesn't intend to promote the replacement of surgeons with technology, it's intended to get aware of the utilities of technology to improve care and deliver personal compassionate care. This quest is for the idea of robotics in the ocular field and improvisation of the field.

“…However, MIS is more difficult than open surgery because it uses a long instrument to reach the desired site through a small incision and provides a view through an endoscope. With the introduction of robotic technology, dexterity and accuracy increased, which, in turn, improved the safety of the procedure and the ergonomics of the operator, thus placing robotic surgery in the spotlight 3–8 …”

Background: Control of the joints of robotic surgical instruments is difficult owing to hysteresis, and tendon twisting due to axial rotation of surgical tools also causes hysteresis. Therefore, a new mechanism is needed to prevent tendon twisting.Methods: Tendon tension and hysteresis change were analysed by observing the movement of the joint depending on whether the tendons twisted for the same input signal. An anti-twist tendon mechanism to prevent twisting was developed.A 3-mm needle driver applied with the proposed mechanism was manufactured. Results:The anti-twist mechanism makes no tension change because of twisting or friction between the tendon and the system, that is, the operating performance was the same regardless of rotation. Conclusion:The proposed mechanism has been verified and can be applied to small surgical instruments 3 mm in size. These findings can be applied in the development of instruments for precise surgeries such as microsurgery.

“…Surgical robots provide a viable solution for the precise implementation of RVC ( Gerber et al, 2020b ; Jara et al, 2020 ). Through the intelligent injection device at the far end of the robot, the surgical robot assists the surgeon in accurately delivering the intelligent injection device to the target blood vessel according to the predetermined path, measures the contact force between the device and the blood vessel tissue in real time, and steadily pushes the thrombolytic drug at the specified speed to improve the accuracy and safety of operation.…”

Retinal vein injection guided by microscopic image is an innovative procedure for treating retinal vein occlusion. However, the retina organization is complex, fine, and weak, and the operation scale and force are small. Surgeons’ limited operation and force-sensing accuracy make it difficult to perform precise and stable drug injection operations on the retina in a magnified field of image vision. In this paper, a 3-DOF automatic drug injection mechanism was designed for microscopic image guiding robot-assisted needle delivery and automatic drug injection. Additionally, the robot-assisted real-time three-dimensional micro-force-sensing method for retinal vein injection was proposed. Based on the layout of three FBG sensors on the hollow outer wall of the nested needle tube in a circular array of nickel-titanium alloys, the real-time sensing of the contact force between the intraoperative instrument and the blood vessel was realized. The experimental data of 15 groups of porcine eyeball retinal veins with diameters of 100–200 μm showed that the piercing force of surgical instruments and blood vessels is 5.95∼12.97 mN, with an average value of 9.98 mN. Furthermore, 20 groups of experimental measurements on chicken embryo blood vessels with diameters of 150–500 μm showed that the piercing force was 4.02∼23.4 mN, with an average value of 12.05 mN.
