title: Validity of the laser refraction technique for meridional measurement.
abstract: This study assessed the validity of the laser refraction technique for determining the refractive status of a given meridian of the eye. A subjective-to-BVA finding was taken on a total of 75 eyes, and the laser technique was then used to refract each of the 2 principal meridians that had been located by the subjective procedure. Correlations between laser and nonlaser findings indicated that the laser technique is a valid method for meridional refraction. Differential findings for against-the-rule astigmatism are also discussed.
