基于Web of Science的巩膜镜研究态势文献计量分析

Bibliometric analysis of scleral lens research trends based on Web of Science

目的通过文献计量方法分析Web of Science数据库中巩膜镜的研究现状。方法检索2013年1月至2022年12月Web of Science核心合集数据库收录的巩膜镜相关文献,采用CiteSpace工具对文献进行可视化分析,对文献发文量、国家及机构分布、核心作者信息、刊文期刊分布及关键词聚类等方面进行综合分析。结果共检索到340篇文献,相关文献分别刊载在54种期刊,平均每种期刊约6.3篇,涉及301位作者;该研究领域覆盖35个国家或地区,共256个研究机构;学科发展主要集中在美国、印度、西班牙、澳大利亚,主要研究领域为巩膜镜(巩膜接触镜)、眼表疾病、角膜水肿、小型巩膜接触镜等方面。近10年来,巩膜镜的研究热点变化趋势为从最初的巩膜接触镜与眼表疾病相结合的研究,到后续的眼表人工置换研究,再到角膜间隙及形状方面的研究。2013—2021年主要关注的主题为眼表疾病、巩膜接触镜及角膜水肿,而在2021年后,眼表疾病和角膜移植术的相关研究有衰落趋势。2013年1月至2022年12月巩膜镜相关的突现词主要包括:第1阶段为巩膜接触镜、移植、抗宿主病、假体装置等研究;第2阶段为眼表生态系统人工置换、不规则角膜等研究;第3阶段为角膜间隙、特有形状等研究。光学相干断层扫描和角膜地形图是巩膜镜研究和验配的常用检查。结论目前巩膜镜主要应用于干眼、角膜扩张、角膜炎、角膜移植(特别是穿透角膜移植术后)和屈光不正;眼表人工置换、角膜间隙及形状是近年的研究热点。

ObjectiveTo analyze the research status of scleral lenses by bibliometric method based on the relevant collection of scleral lenses in the Web of Science database.MethodsUsing the scleral lens-related literature collected in the Web of Science Core Collection database in the past 10 years (January 2013 to December 2022) as the object of analysis, bibliometric method and CiteSpace tools were used to conduct visual analysis of the literature.A comprehensive analysis of the volume of literature published, the distribution of countries and institutions, the information of core authors, the distribution of journals, and keyword clustering was performed.ResultsA total of 340 articles were retrieved, which were published in 54 journals, with an average of 6.3 articles per journal, involving 301 authors.Research in this area covered 35 countries or regions, and 256 research institutions were involved.Discipline development was mainly in the United States, India, Spain and Australia.The main focus was on scleral lens (scleral contact lens), ocular surface disease, corneal edema, miniature scleral lens, etc.In the past 10 years, the trend of research hot topics in scleral lenses had shifted from the initial study of combining scleral contact lenses with ocular surface diseases to the subsequent study of prosthetic replacement of the ocular surface ecosystem, and the exploration of corneal clearance and shape.From 2013 to 2021, the main focuses were ocular surface diseases, scleral contact lenses, and corneal edema.After 2021, research on ocular surface diseases and keratoplasty declined.From January 2013 to December 2022, emergent keywords related to scleral lens mainly included scleral contact lens, transplantation, anti-host disease, prosthetic device in the first stage, artificial replacement of ocular surface ecosystem and irregular cornea in the second stage, and the research on corneal gap and characteristic shape in the third stage.Optical coherence tomography and corneal topography were commonly used examinations for scleral lens research and fitting.ConclusionsAt present, the scleral lens is mainly used for dry eye, corneal diseases, corneal ectasia, keratitis, and corneal transplantation, especially after penetrating keratoplasty and refractive errors.Prosthetic replacement of the ocular surface ecosystem, and the exploration of corneal clearance and shape are the research hotspots in scleral lenses.
