Consecutive cases of keratoconus or ectasia post-refractive surgery newly seen or reviewed in consultation by Dr. Damien Gatinel since January 2017 are included in the study.
Other than the full set of paraclinical investigations (including manifest refraction, topography, corneal hysteresis, other biomechanical measurements and aberrometry), a detailed history taking of the presence or absence of eye rubbing and the patients’ sleeping habits is performed, and pictures of their eye profiles and sleeping positions taken. Video recordings of eye rubbing techniques and interviews of patients and their relatives are initiated whenever appropriate. These are all taken with the patients’ full informed consent.
Progression or stabilization of the keratoconus is documented objectively via difference maps.
