What this trial studies

This observational study aims to validate the effectiveness of a Terahertz (THz) scanning system in assessing corneal edema and scars. Participants with these conditions will undergo THz scanning, followed by conventional clinical examinations to characterize their corneal lesions. The study will evaluate the correlation between THz scan measurements and standard clinical methods, hypothesizing that THz scanning can accurately assess corneal hydration levels. This innovative approach seeks to provide a quantitative tool for monitoring disease progression and aiding surgical decisions.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 21 and older with corneal endothelial dysfunction or corneal scars without corneal edema.

Not a fit: Patients with active inflammation or infection in the eyes, or those unable to comply with study requirements, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved monitoring and management of corneal diseases, potentially reducing the need for invasive procedures.

How similar studies have performed: While the use of THz scanning in other medical fields has shown promise, this specific application in corneal assessment is relatively novel and untested.
