Automated Keratometry

An auto-refractor or automated refractor is a computer controlled device used for a quick and accurate estimation of refractive error (spectacle prescription). This is achieved by measuring how light is changed as it enters the eye and requires no input or feedback from the patient. Automated refraction is a quick a painless procedure which requires the patient to look at a picture of a road with a hot air balloon in the distance whilst the machine takes accurate measurements.

This process takes a matter of seconds to perform and does not affect vision, meaning driving afterwards is safe. At Peter Ivins Eye Care we use the latest auto-refractor, which will not only measure the refractive error of the eye but is also an automated keratometer allowing for quick and accurate measurements of the curvature of the eye used in contact lens fitting
