As a common type of refractive error, astigmatism has always been one of the important factors affecting visual quality in clinical practice and it is quite an important public health burden. This study aims to evaluate astigmatism research and the clinical application of the vector method of the past half-century through a broad scientometric analysis, and to explore its reference value for guiding clinical treatment.
The literature search was conducted on the Web of Science for astigmatic vector studies published from 1965 to August 2024. Retrieved publications were analyzed by the number of annual publications, prolific countries, and researchers, core publications and journals, and the number of citations through descriptive statistics. Collaboration networks and keyword analysis were visualized by VOSviewer and CiteSpace.
One thousand and fifty-nine publications were included for a visualized analysis. Vector methods help researchers to describe astigmatism specialized, and clinicians are mainly focused on the correction of astigmatism in both corneal and cataract surgery. Journal of Cataract and Refractive Surgery was the core journal for this field. The United States accounts for the largest proportion of publications and Australia had the highest citation ratio. Through the keyword analysis, the network identified 4 major research trends of corneal refractive surgery, penetrating keratoplasty, cataract surgery, and epidemiological surveys of astigmatism. "Photorefractive keratectomy," "postoperative astigmatism" and "surgery" had significant burst strength and continuous attention to the astigmatism vector analysis.
Vector analysis is the most commonly used method to evaluate astigmatism and could significantly improve the accuracy of astigmatism correction, particularly in areas of refractive and cataract surgery. The application of vector analysis is beneficial in guiding the design of surgical incisions, determining the nomogram, optimizing the surgical protocol, and improving the accuracy of astigmatism correction. Meanwhile, the popularization of vector method will help to improve the accuracy of astigmatism analysis and promote the benign development of public health.
散光作为一种常见的屈光不正类型，一直是临床实践中影响视觉质量的重要因素之一，也是一项相当重要的公共卫生负担。本研究旨在通过广泛的科学计量分析，评估过去半个世纪散光研究及矢量法的临床应用，并探讨其对指导临床治疗的参考价值。
在科学网（Web of Science）上检索1965年至2024年8月发表的散光矢量研究文献。通过描述性统计分析检索到的出版物的年发表数量、高产国家和研究人员、核心出版物和期刊以及被引次数。利用VOSviewer和CiteSpace对合作网络和关键词分析进行可视化。
纳入1059篇出版物进行可视化分析。矢量法有助于研究人员更专业地描述散光，临床医生主要关注角膜和白内障手术中散光的矫正。《白内障与屈光手术杂志》是该领域的核心期刊。美国的出版物占比最大，澳大利亚的被引率最高。通过关键词分析，该网络确定了角膜屈光手术、穿透性角膜移植术、白内障手术和散光流行病学调查4个主要研究趋势。“光性屈光性角膜切削术”“术后散光”和“手术”具有显著的突发强度，且对散光矢量分析持续受到关注。
矢量分析是评估散光最常用的方法，可显著提高散光矫正的准确性，尤其是在屈光和白内障手术领域。矢量分析的应用有助于指导手术切口设计、确定列线图、优化手术方案以及提高散光矫正的准确性。同时，矢量法的推广将有助于提高散光分析的准确性，促进公共卫生的良性发展。
