Is the Autorefractor reading closest to manifest refraction? A comparison of the patient's previous spectacles and the 6600 Autorefractor reading.
In a study of 56 patients, the old glasses of a previously refracted individual were as close to the final subjective refraction as the reading obtained with a 6600 Autorefractor. Therefore, the previous spectacle correction might logically be used for the starting point of a subjective refraction, with retinoscopy or automatic refractor results being used for this purpose in patients whose previous spectacle refraction is unknown or in the first refraction of an aphakic patients.
