The EM-3000 specular microscope has a state-of-the-art color touch screen allowing for ease of operation and speed in its results. The device also measures the thickness of the cornea and takes sharp, clear images of the endothelium, says Tomey. The EM-3000 has an internal computer that automatically analyzes the cells and displays the morphology in a unique color images. The unit can send data to a photo printer, practice management server or both. The EM-3000 has seven fixation targets, making peripheral photography easy to perform and more cells are counted for greater accuracy.

Alignment of the device was followed the standard guidelines of the manufacturer, to include an internal calibration check before beginning data acquisition to ensure that the system could be operated by a technician without any alignment or calibration requirements. After initial alignment, all data were collected with the self-contained fitting software (Tomey OA-3000 Fit) to register the data for the subsequent analysis. The AL, CCT, ACD, Keratometer readings and CD data were automatically calculated. The process of measurement took approximately 1 minute and the measurements were obtained with the subject focused on the fixation target of the lens of the device.
In the first session, 2 observers obtained 3 consecutive scans using the Tomey OA-2000 biometer, respectively, to assess intraobserver repeatability and interobserver reproducibility; ocular parameters were also measured by the IOLMaster (version 5.4.4.0006) in the same session. The average of AL, Keratometer readings, PD and CD obtained by the Tomey OA-2000 biometer by the first observer were used to compared with those obtained by IOLMaster. In the second session, about 1 week later, 1 observer obtained another 3 consecutive scans using the Tomey OA-2000 biometer to assess intersession reproducibility. All measurements were performed at least 3 hours after waking between 10 AM and 5 PM to minimize variations in the results.
The present study has several strengths. We performed a study to assess the precision of ocular parameters measured by Tomey OA-2000 biometer in healthy eyes with good repeatability and reproducibility. Most of the previous studies evaluated the precision of ocular parameters measured by Tomey OA-1000 or IOLMaster (with its predecessor, OA-2000). Furthermore, this is the first study to assess the repeatability and reproducibility of ocular parameters measured by Tomey OA-2000 biometer in healthy eyes. The ICCs and CoV values for all the parameters evaluated in this study were excellent, and the CD was the most unstable parameter. This is due to the fact that the CD was dependent on the ocular pupil diameter, so the ocular movement during the measurements may affect the stability. This is the first study to assess the precision of ocular parameters measured by Tomey OA-2000 biometer in healthy eyes. A limitation of the study is that the test-retest variability was not evaluated in this study, as the measurement was performed in a single session. Although the measurements were performed one examiner, for all the parameters evaluated in the present study, the intra-observer repeatability and reproducibility was excellent. This is due to the fact that the test and retest values were measured by the same observer. The good repeatability of intra-observer could be partially due to the good reproducibility of the data collected by the same device. Another limitation of this study is that the age, sex and race of the subjects were not considered. However, we found in our previous studies that age, sex and race could not influence the precision of ocular biometry[ 30, 31 ]. A prospective study is required to evaluate the effect of age, sex and race on precision of the ocular parameters. Furthermore, we only investigated eyes without eye disease. So, further studies are required to assess the impact of ocular disease on the precision of biometry.
