[Reproducibility of measurement of intraocular lens location in situ with an anterior eye segment analysis system].
The reproducibility of the measurement (accuracy of repeated measurement) of intraocular lens (IOL) location in situ was studied using an anterior eye segment analysis system (NIDEK EAS-1000). The measurements were performed as follows: (1) errors at photography: 1) errors by the individual photographer 2) errors among three photographers. (2) errors at analysis: 1) errors by individual analysists 2) errors among six analysists. The greatest standard deviation was the accuracy of repeated measurement. Accuracy of repeated measurement (tilt and decentration) was (1) 1) 1.104 degrees, 0.083 mm, (1) 2) 0.866 degrees, 0.072 mm, (2) 1) 0.597 degrees, 0.079 mm, (2) 2) 0.562 degrees, 0.079 mm. From the data obtained in this study, the reproducibility of the EAS-1000 was satisfactory for measurement of IOL location.
