Summary

Most practitioners fitting scleral lenses (SLs) for keratoconus still rely on traditional diagnostic lens fitting. Newer image- and impression-based technologies are less commonly used, particularly in community practices.

Area of Science:

  • Ophthalmology
  • Optometry
  • Biomedical Engineering

Background:

  • Scleral lenses (SLs) offer customized vision correction for conditions like keratoconus.
  • Traditional diagnostic lens fitting and newer image/impression-based technologies are available for SL fitting.
  • Understanding the current adoption of these fitting technologies is crucial for guiding future practice.

Purpose of the Study:

  • To assess the availability and utilization of scleral lens fitting technologies in patients with keratoconus.
  • To compare technology adoption based on practice type, location, and fitting volume.

Main Methods:

  • An online survey was distributed to practitioners fitting SLs for keratoconus.
  • Practitioners reported their practice type, location, and estimated SL fitting methods (diagnostic, image-based, impression-based).
  • Data were analyzed comparing technology access and usage across different practice settings and practitioner volumes.

Main Results:

  • 423 practitioners participated in the survey.
  • Image- and impression-based technologies were more prevalent in academic and high-volume practices.
  • Practitioners utilized these advanced technologies for a median of 5-12% of their SL fittings.

Conclusions:

  • The majority of practitioners currently favor traditional diagnostic lens fitting for scleral lenses in keratoconus patients.
  • Wider adoption of advanced image- and impression-based fitting technologies may be warranted.
