"According to prespecified criteria [] outlined by the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines, this study protocol was registered with PROSPERO (No. CRD42023403759). Two investigators (PZ and CG) independently searched eight databases to identify all the eligible literature from January 01, 1997, to February 20, 2023: PubMed, the Cochrane Library, Embase, Web of Science, Chinese National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature (CBM), Wanfang and VIP, by a combination of Medical Subject Headings [MeSH] terms and keywords. The ClinicalTrails and China Clinical Trials Registry were also searched manually for unpublished relevant literature. It contained four core components, linked using the AND operator: (1) phakic intraocular lenses (e.g. phakic, implantable collamer lens, ICL, intraocular lens implantation); (2) vault (e.g., arch height, arch highness, high arch); (3) risk factor (e.g., influenc* factor, relate*, predict*); (4) observational study (e.g., case-control study, cohort study, case series study). Search terms were reviewed by an independent specialist (HY) to ensure its comprehensive and relevant."
