The META is an innovative and non-invasive examination instrument for a variety of common eye diseases. The integrated multimodality device combines digital slit lamp, fundus camera, OCT, refractometer, optical biometry and visual acuity test (near and distance) that facilitate a comprehensive ophthalmic examination. In the current study, all participants will undergo the measurements provided by the META and by traditional examination modalities (including digital slit lamp, fundus camera, OCT, refractometer, optical biometry and visual acuity test) in a random order. The participants will need to complete several questionnaires to investigate their preference and confidence to receive the META exams in the future.
We have developed a Multimodal Equipment for Teleophthalmology Assessment (META) device. This novel device is compact, portable and suitable for packaging and express delivery. With this device, there is a potential to implement a new concept of hospital-at-home eye care model. The present study is designed to validate the META device for future clinical usage and investigation. We will compare the performance of the META device with those provided by commercial devices in terms of image quality of optical coherence tomography (OCT), anterior segment and fundus camera, and evaluate the level of agreement in lesion detection and quantitative measurements between META and other commercial devices (e.g., Heidelberg Spectralis OCT, Haag-Streit BQ900 Slit-lamp imaging, Canon CR-2 fundus imaging, Zeiss IOL Master 500).
