Bibliometric and visual analysis of global research on premium IOLs from 2000 to 2022

Abstract

Background Premium intraocular lenses (PIOLs), particularly those using multifocal, extended depth of focus (EDoF) and toric technologies, have been in clinical use for decades, giving countless cataract patients the ability to see the world clearly again. To explore the development process, research status and future development trends of PIOLs, we explored research on PIOLs from the past 22 years through bibliometrics. Methods The literature search was performed on the Web of Science and included PIOL studies published between 2000 and November 2022. The retrieved literature was collated and analyzed by R-tool's Bibliometrix package, CitNetExplorer, CiteSpace and other software. Results We obtained a total of 1801 articles about PIOLs, most of which were published in Spain and the United States. The organization that published the most articles was the University of Valencia in Spain. Alió JL, and Montés-Micó R, from Spain were the most influential authors in this field. The Journal of Cataract and Refractive Surgery and Journal of Refractive Surgery were the core journals for this field; the top 10 cited articles mainly focus on postoperative satisfaction with multifocal IOLs and postoperative results of toric IOLs. Through a key word analysis, we found that trifocal IOLs, astigmatism and EDoF IOLs are the most discussed topics at present, and the importance of astigmatism and the clinical application of the new generation of PIOL are the emerging research trends. In addition, we found that researchers are not only focusing on the application of cutting-edge technology but also paying increasing attention to patients' subjective satisfaction. Conclusion Bibliometric analysis can effectively help to identify multilevel concerns in premium intraocular lens (PIOL) research and we found that in the past 2 decades, the research of PIOL has made rapid development and gradually matured, countless cataract patients can regain excellent visual quality and improve their quality of life after surgery. The current research hotspots regarding PIOL are the application of EDoF IOL as well as trifocal IOL and its toric models and the development of new types of PIOLs.
