title: Accuracy of intraocular lens powers calculated from A-scan biometry with the Echo-Oculometer.
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.
