Tele-Refraction in Tele-Eye Care Settings: A Commentary
Author(s): Nicolas Blais*, Benoit Tousignant and Jean-Marie Hanssens
Uncorrected refractive errors are the leading cause of visual impairment globally. The access to primary eye care,
which includes refraction, is limited by the lack of refractionists and the remoteness of certain populations. Remote
refraction could be a promising way to address this issue. There are two types of remote refraction: web-based
refraction testing and clinical tele-refraction. Online refraction is the use of web-based tools or devices that allow for
subjective refractive measurements. This type of remote refraction is unassisted, while clinical tele-refraction involves
an in-person technician, or professional, and a remote eye care provider in a synchronous, asynchronous or hybrid
modality. Studies have found that both online refraction and clinical tele-refraction can be equivalent to in-person
subjective refraction. Tele-refraction also appears to h.. View More»
