NCT06859398

Brief Summary

This observational study aims to collect real-world wavefront aberrometry and corneal/scleral topography data from individuals with keratoconus and other corneal ectatic disorders. This data will be used to develop and refine a methodology for designing custom-fitted scleral contact lenses with embedded active light management technology. The study will focus on characterizing the optical imperfections (aberrations) and corneal/scleral shape variations in this population to optimize lens design for improved vision and comfort.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥ 18y
  • Provide written Informed Consent
  • Diagnosed with keratoconus and/or any other type of ectatic corneal disorder
  • Cornea considered to be clinically stable at the discretion of the investigator (e.g. no recent cross linking performed, no current corneal sutures, no corneal sutures recently removed).
  • Willing to remove current contact lenses for a minimum of 48 hours prior to performing the pentacam AXL Wave scan, if applicable.

You may not qualify if:

  • Known active disease-related ocular surface problem (i.e. microbial keratitis)
  • History of ocular pathologies that might lead to incomplete/incorrect eye surface scan AND wavefront aberrometry, at the discretion of the investigator
  • Use of fluorescein in the eye, within 12 hours prior to the pentacam AXL Wave scan is performed
  • Contact lens refitting within one month prior to the pentacam AXL Wave scan, as this can significantly impact the corneal or scleral surface.
  • Currently wearing hybrid contact lenses
  • Having worn contact lenses within 48 hours prior to performing the pentacam AXL Wave scan. Note: this criteria might not be applicable yet at the time of signing ICF, but needs to be confirmed prior to performing the Pentacam AXL Wave Scan
