New method for diagnosing keratoconus using advanced imaging technology
A Study on Evaluating the Consistency of CASIA2, Pentacam, and Corvis ST Measurement Parameters and the Diagnostic Efficacy of Early Keratoconus
Tianjin Eye Hospital · NCT06152484
This study is testing a new imaging device to see if it can better diagnose keratoconus by comparing its measurements with those from older devices.

What this trial studies
This observational study compares corneal topography measurements obtained from a novel optical coherence tomography device (CASIA2) with those from established devices like Pentacam and Corvis ST. The aim is to evaluate the effectiveness of these technologies in screening and diagnosing keratoconus, particularly focusing on their consistency in measuring corneal parameters such as curvature and thickness. By analyzing these different imaging techniques, the study seeks to improve diagnostic accuracy for keratoconus and its subclinical forms.
Who should consider this trial
Good fit: Ideal candidates include individuals with a best corrected visual acuity of 20/20 and no significant ocular diseases other than myopia and astigmatism.
Not a fit: Patients with other ocular diseases, previous ocular surgeries, or those who are pregnant or lactating may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to more accurate and early diagnosis of keratoconus, improving patient outcomes.
How similar studies have performed: While the approach is innovative, similar studies have shown promise in using advanced imaging techniques for diagnosing keratoconus.
