About this trial
This observational study aims to establish the safety profile of the use of Terahertz (THz) scanning system on corneal diseases. Participants with "non-seeing" eyes but normal corneas will undergo THz scanning. Eye examinations will be conducted at baseline, immediately after scanning, and at 1 day, 1 week, and 1 month post-scanning. These examinations will include measurements of visual acuity, eye structural, retinal health, corneal cell morphology, and corneal nerve status. The investigators hypothesize that the THz scanning system is safe for application to the human cornea.
