The Echo-oculometer is a relatively inexpensive ultrasonic device for measuring anterior chamber depth and axial length prior to lens implantation. It is uncomplicated, easy to use and functioned very well in this limited study, giving an average error of 0.98 D when preoperative measurements were compared to postoperative refraction.
回声眼压计是一种相对廉价的超声设备，用于在晶状体植入术前测量前房深度和眼轴长度。它结构简单，易于使用，并且在这项有限的研究中运行良好，将术前测量值与术后验光结果相比较时，平均误差为0.98屈光度。
