Abstract

Purpose: Publication metrics are derived for the fields of silicone hydrogel (SH) and daily disposable (DD) contact lenses.

Methods: A search of the Scopus database for papers in the fields of SH and DD contact lenses found 979 SH and 291 DD papers. Subject-specific h-indices for SH lenses (hSH-index) and DD lenses (hDD-index) were derived, in relation to five categories - authors, institutions, countries and journals - to serve as measures of impact. A short list of the most impactful entities was generated for each of the above five categories in the SH and DD fields.

Results: A paper entitled "Soft contact lens polymers: An evolution" by Nicholson and Vogt was the most highly cited article (495 citations) in both SH and DD fields. The most impactful entities for the SH and DD fields were: authors - Lyndon Jones (hSH = 33) and Philip Morgan (hDD = 15); institutions - the University of Waterloo (hSH = 37) and the University of New South Wales (hDD = 15); countries - the United States (hSH = 45) and the United Kingdom (hDD = 24); and journals - Optometry and Vision Science (hSH = 33) and Contact Lens and Anterior Eye (hDD = 17). Overall, the SH field (hSH = 64) is far more impactful than the DD field (hDD = 34).

Conclusions: Impactful papers, authors, institutions, countries and journals in the SH and DD fields are identified. Optometry is revealed as the leading profession in relation to SH and DD publications.

Keywords: Bibliometric analysis; Contact lens; Daily disposable; Silicone hydrogel; h-index.
