Clinical evaluation of alignment methods using the Dioptron II

10 March 1982

Abstract

A clinical investigation into the significance of alignment methods as used with the Dioptron II Automated. Refractor was compared to the subjective refraction. A total of 110 eyes were tested. using two differing alignment modes: 1) instrument alignment target centered with the pupil, i.e. on the pupil axis; 2) instrument alignment target centered on the corneal light reflex, i.e. on the line of sight. Results showed no significant difference between either of the alignment methods when they were compared to the subjective refraction examination results.
