Summary
Robot-assisted vitreoretinal surgery is emerging but lacks extensive human clinical evidence. Current research focuses on technical aspects, positioning it as a specialized tool for complex retinal procedures rather than a universal replacement for manual surgery.
Area of Science:
- Ophthalmology
- Medical Robotics
- Biomedical Engineering
Background:
- Robot-assisted vitreoretinal surgery is a developing field for complex retinal procedures.
- Its clinical maturity and global development landscape require comprehensive mapping.
Purpose of the Study:
- To map the global development of robot-assisted vitreoretinal surgery using bibliometric and visualization techniques.
- To analyze publication trends, collaborations, and keyword evolution in this interdisciplinary field.
Main Methods:
- Bibliometric analysis of records from Web of Science Core Collection (2008-2026).
- Utilized R (Bibliometrix), CiteSpace, and SCImago Graphica for data analysis.
- Included analysis of publication output, collaboration networks, citation patterns, journal distribution, and keyword evolution.
Main Results:
- Publication output increased significantly after 2017, with the US and China leading.
- The field spans ophthalmology, medical robotics, imaging, and computer-assisted interventions.
- Keywords show growing interest in subretinal injection, OCT-guided procedures, AI, and computer vision.
Conclusions:
- Robot-assisted vitreoretinal surgery is currently more of a selective precision platform than a universal surgical replacement.
- The field shows a predominance of technical/simulation and preclinical studies over human clinical trials.
- Future research should focus on multicenter validation, clinical outcomes, integration, training, and cost-effectiveness.
