Objective

To analyze the research status of scleral lenses by bibliometric method based on the relevant collection of scleral lenses in the Web of Science database.

Methods

Using 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.

Results

A 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.

Conclusions

At 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.
