CLINICAL-EVALUATION OF AUTOMATED REFRACTION IN ANTERIOR-CHAMBER PSEUDOPHAKIA

Automated refraction with the Canon RK-1 Autoref keratometer was evaluated in 85 eyes of 85 patients with an anterior chamber intraocular lens implant and a best corrected visual acuity of at least 6/12. Autorefraction readings were obtained in 80 (94%) of these eyes. The agreement between autorefraction and clinical refraction data was 89% for spherical equivalence < 0.51 dioptres (D), 91% for sphere power < 0.51 D, 82% for cylinder power < 0.51 D, and 91% for cylinder axis < 11-degrees. Autorefraction provides acceptably accurate postoperative refraction values in anterior chamber pseudophakia.
