  • Title: Accuracy of intraocular lens powers calculated from A-scan biometry with the Echo-Oculometer.
    Author: Schachar RA, Levy NS, Bonney RC.
    Journal: Ophthalmic Surg; 1980 Dec; 11(12):856-8. PubMed ID: 7207958.
    Abstract:
    Our study indicates that by using data obtained from the Model 3000 Echo-Oculometer, 93% of eyes receiving intraocular lenses will have an optimal visual acuity which will differ by less than three diopters from that calculated. With oscilloscopic control of the end points, the Echo-Oculometer provided good inter-observer reproducibility and low variability.
