KeratoConus Data Acquisition With Topography and Aberrometry

Inclusion Criteria: * 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. Note: In case only 1 eye is diagnosed with keratoconus, both eyes will be scanned, as long as none of the exclusion criteria apply to that eye Exclusion Criteria: * 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 Note: In case any of the above exclusion criteria are met in 1 eye, but not in the other, it's sufficien…
