PURPOSE: To analyze the state of scientific publications in multifocal contact lenses field through a bibliometric study. METHODS: The database used to carry out the study was SCOPUS and contained the descriptors "multifocal contact lens", "bifocal contact lenses", "progressive contact lenses" and "presbyopia contact lenses", limited to the fields of title, keywords and abstract. The indicators applied in this research were: doubling time and annual growth rate, Price's transience index, Lotka's law of scientific productivity, and Bradford's zones. RESULTS: A total of 346 articles were published between 1960 and 2019. The growth in the number of publications matches the exponential adjustment slightly better (R = 0.53). The duplication time was 13.2 years. The productivity level is focused on articles with an average number of authors of just 2.06 per article. The Bradford core was formed by two journals, Optometry and Vision Science and Eye and Contact Lens. CONCLUSIONS: Research on multifocal contact lenses has exponential growth, without evidence of having reached a saturation point. The main countries in scientific production in this field are the United States and Australia.
目的:通过文献计量学研究分析多焦点接触镜领域的科学出版物状况。
方法:本研究使用的数据库是 SCOPUS,包含了“多焦点接触镜”、“双焦点接触镜”、“渐进式接触镜”和“老视接触镜”等主题词,限定在标题、关键词和摘要字段。本研究应用的指标包括:倍增时间和年增长率、普赖斯指数的短暂性、洛特卡科学生产力定律和布拉德福区。
结果:1960 年至 2019 年共发表了 346 篇文章。出版物数量的增长与指数调整略为吻合(R=0.53)。倍增时间为 13.2 年。生产力水平集中在平均每位作者仅撰写 2.06 篇文章的文章上。布拉德福核心由 Optometry and Vision Science 和 Eye and Contact Lens 这两本期刊组成。
结论:多焦点接触镜的研究呈指数增长,没有达到饱和点的迹象。该领域科学产出的主要国家是美国和澳大利亚。
