      Abstract

      Objectives

      To describe current components of scleral lens curricula at U.S. based optometry colleges and universities.

      Methods

      Contact lens educators were surveyed between June 2019 and August 2019 regarding their optometric scleral lens curriculum. Respondents were asked to describe their experience and involvement in optometric scleral lens education as well as to describe components of scleral lens curricula. Educators were also asked to identify sources of information upon which they rely on in order to stay informed about new developments and best practices in scleral lens prescription and management.

      Results

      Most programs begin scleral lens education during the 3rd year of optometric education (71.2 %; n = 52). Students complete an estimated 18.0 ± 18.1 (range 2–100) scleral lens evaluations during training (n = 36). Ideal fitting characteristics taught include central corneal clearance of 206.3 ± 44 microns (range 150−350, n = 40), limbal clearance of 62.1 ± 23.6 microns (range 20−100, n = 36) with one clock hour or less of conjunctival vascular compression (n = 41). Educators ranked in-person continuing education (61 %, 22/36) followed by contact lens laboratory consults (22 %, 8/36) as the two most important sources of information on best practices in scleral lens prescription and management.

      Conclusions

      Educators are uniquely positioned to guide the next generation of eyecare providers by incorporating and disseminating new research findings into their scleral lens curricula.
