Validation of the Use of Terahertz Scanning System on Corneal Scars and Corneal Edema

The THz scanning system is non-invasive and non-contact. It is a prototype developed by Institute of Materials Research and Engineering (IMRE), A\*STAR, Singapore and is performed for the purpose of research. THz scanning will provide safety data in human and the measurement of cornea hydration status. Each THz scan will take approximately 1 second. Real-time data will be generated when participants are positioned in front of the device.
