“…The difference between UBM and AL-scan was signi cant, but the correlation was week (r=0.294). In glaucoma patients, there was a statistically signi cant difference between the mean values of ACD, but not CCT when compared anterior segment measurements obtained using the Lenstar and Pentacam 14 . The ACD and CCT measurements obtained from the Lenstar and the Pentacam showed excellent correlation in cataract subjects and can be used interchangeably, this is consistent with previous reports 1,15,16 .…”

Purpose: To test whether some biometry measurements provided by the Lenstar LS900 compared well with the AL-Scan, Pentacam rotating Scheimpflug camera, Ultrasound Biomicroscopy (UBM) and Tomey EM-3000. Methods: 201 patients having routine cataract surgery had standard preoperative assessment. In this clinical study, the axis length (AL) and lens thickness (LT) were taken by Lenstar LS900 and AL-Scan; anterior chamber depth (ACD) were taken by Lenstar LS900, A-scan, Pentacam and UBM; central corneal thickness (CCT) were taken by Lenstar LS900, Pentacam and Tomey EM-3000. The results were compared using a Wilcoxon-Mann-Whitney U test and Pearson correlation calculations. Agreement was assessed through intraclass correlation coefficients and Bland-Altman plots.Results: The highest correlation was found between Lenstar and AL-Scan for AL (r = 0.975; P <0.001). For LT measurements, the correlation between these two devices was also good (r = 0.699; P <0.001). Excellent correlations were showed between Lenstar and pentacam or UBM for ACD (r=0.948, 0.704, respectively; both P <0.001), but AL-scan (r=0.453, P <0.001). According to CCT, correlation between Lenstar and Pentacam or Tomey EM-3000 were both excellent (r=0.817, 0.882, respectively; both P <0.001).Conclusions: In phakic eyes of cataract patients, measurements of AL, LT, ACD, and CCT from Lenstar LS900 yielded results that correlated very well with other clinical instruments.

The physical conditions for optical biometry are reviewed, and the difference between conventional axial length measurements and segmented, or sum-of-segments axial length readings explained. Segmented axial length reading may have an advantage over the conventional axial length readings—especially in the extreme range—and examples are given of the difference between the two methods and also between different biometers.

Comparison of anterior segment measurements with LenStar and Pentacam in patients with newly diagnosed glaucoma

Abstract: There was a statistically significant difference between the mean values of ACD and WTW measured with the LenStar and Pentacam. These biometric devices should not be used interchangeably. It should be appropriate to use the same device on follow-up of glaucoma patients.
