However, to date, the impact of pterygium and its surgical removal on refractive errors has not been thoroughly compiled in a comprehensive study.

Relevant articles published up to December 2024 were searched and collected from four electronic databases: PubMed, Scopus, MEDLINE, and Web of Science.
