Myopic corneal refractive surgery is one of the most prevalent ophthalmic procedures for correcting ametropia. This study aimed to perform a bibliometric analysis of research in the field of corneal refractive surgery over the past 40 years in order to describe the current international status and to identify most influential factors, while highlighting research hotspots.
A bibliometric analysis based on the Web of Science Core Collection (WoSCC) was used to analyze the publication trends in research related to myopic corneal refractive surgery. VOSviewer v.1.6.10 was used to construct the knowledge map in order to visualize the publications, distribution of countries, international collaborations, author productivity, source journals, cited references, keywords, and research hotspots in this field.
A total of 4,680 publications on myopic corneal refractive surgery published between 1979 and 2022 were retrieved. The United States has published the most papers, with Emory University contributing to the most citations. The Journal of Cataract and Refractive Surgery published the greatest number of articles, and the top 10 cited references mainly focused on outcomes and wound healing in refractive surgery. Previous research emphasized "radial keratotomy (RK)" and excimer laser-associated operation methods. The keywords containing femtosecond (FS) laser associated with "small incision lenticule extraction (SMILE)" and its "safety" had higher burst strength, indicating a shift of operation methods and coinciding with the global trends in refractive surgery. The document citation network was clustered into five groups: (1) outcomes of refractive surgery: (2) preoperative examinations for refractive surgery were as follows: (3) complications of myopic corneal refractive surgery; (4) corneal wound healing and cytobiology research related to photorefractive laser keratotomy; and (5) biomechanics of myopic corneal refractive surgery.
The bibliometric analysis in this study may provide scholars with valuable to information and help them better understand the global trends in myopic corneal refractive surgery research frontiers. Two stages of rapid development occurred around 1991 and 2013, shortly after the innovation of PRK and SMILE surgical techniques. The most cited articles mainly focused on corneal wound healing, clinical outcomes, ocular aberration, corneal ectasia, and corneal topography, representing the safety of the new techniques.
近视角膜屈光手术是矫正屈光不正最常见的眼科手术之一。本研究旨在对过去40年角膜屈光手术领域的研究进行文献计量分析，以描述当前的国际现状，确定最具影响力的因素，并突出研究热点。
基于科学网核心合集（WoSCC）进行文献计量分析，以分析近视角膜屈光手术相关研究的发表趋势。使用VOSviewer v.1.6.10构建知识图谱，以可视化该领域的出版物、国家分布、国际合作、作者生产力、来源期刊、被引参考文献、关键词和研究热点。
检索到1979年至2022年间发表的4680篇关于近视角膜屈光手术的出版物。美国发表的论文最多，埃默里大学的论文被引用次数最多。《白内障与屈光手术杂志》发表的文章数量最多，前10篇被引参考文献主要集中在屈光手术的结果和伤口愈合方面。以往的研究重点是“放射状角膜切开术（RK）”和准分子激光相关的手术方法。与“小切口基质透镜切除术（SMILE）”及其“安全性”相关的包含飞秒（FS）激光的关键词具有较高的爆发强度，表明手术方法的转变，这与屈光手术的全球趋势一致。文献引用网络聚类为五组：（1）屈光手术的结果；（2）屈光手术的术前检查；（3）近视角膜屈光手术的并发症；（4）与光折射性角膜切削术相关的角膜伤口愈合和细胞生物学研究；（5）近视角膜屈光手术的生物力学。
本研究中的文献计量分析可为学者提供有价值的信息，帮助他们更好地了解近视角膜屈光手术研究前沿的全球趋势。在准分子激光原位角膜磨镶术（PRK）和SMILE手术技术创新后不久，分别在1991年和2013年左右出现了两个快速发展阶段。被引用次数最多的文章主要集中在角膜伤口愈合、临床结果、眼像差、角膜扩张和角膜地形图方面，代表了新技术的安全性。
