“…Furthermore, Anterion showed good agreement in various biometric parameters with other biometers, e.g. IOL Master500 (a PCI system) [ 14 , 18 ], Pentacam (Scheimpflug system) [ 19 ], MS 39 (combined placido disk and AS-OCT) [ 14 ], and CASIA SS 100 (SS-OCT) [ 20 ]. Anterion could be applied for reliable irido-corneal angle evaluation prior to and after LPI in PACD patients [ 21 ].…”

Purpose To investigate agreement between 2 swept source OCT biometers, IOL Master700 and Anterion, in various ocular biometry and intraocular lens (IOL) calculations of primary angle-closure disease (PACD). Setting Rajavithi Hospital, Bangkok, Thailand. Design Prospective comparative study. Methods This study conducted in a tertiary eye care center involving biometric measurements obtained with 2 devices in phakic eye with diagnosis of PACD. Mean difference and intraclass correlation coefficient (ICC) with confidence limits were assessed, and calculations of estimated residual refraction of the IOL were analysed using Barrett’s formula. Results Sixty-nine eyes from 45 PACD patients were enrolled for the study. Excellent agreement of various parameters was revealed, with ICC (confidence limits) of K1 = 0.953 (0.861–0.979), K2 = 0.950 (0.778–0.98), ACD = 0.932 (0.529–0.978), WTW = 0.775 (0.477–0.888), and LT = 0.947 (0.905–0.97). Mean difference of axial length (AL) was -0.01 ± 0.02 mm with ICC of 1.000. IOL calculation was assessed with Barrett’s formula, and Bland-Altman plot showed excellent agreement in the results of the 2 devices for the IOL power and estimated post-operative residual refraction (EPR). Conclusions Mean differences of biometric parameters, obtained with IOL Master700 and Anterion, were small, and ICC showed excellent concordance. No clinical relevance in calculation of IOL power was found, and the two devices appeared to be comparably effective in clinical practice.

“…The IOLMaster 500 is based on the partial coherence interferometry principle; however, the device uses a different principle to measure the ACD. The ACD was measured by projecting a 0.7 mm wide slit-light beam at 30° and assessing the distance between the light reflection of the anterior corneal surface and anterior lens surface [ 12 ]. The IOLMaster 500 measures AL based on the partial coherence interferometry principle using a laser diode generating 780 nm infrared light of short-coherence light [ 13 , 14 ].…”

Purpose: To evaluate the level of agreement between ANTERION (Heidelberg Engineering, Heidelberg, Germany), OA-2000 (Tomey, Nagoya, Japan), and IOLMaster 500 (Carl Zeiss AG, Jena, Germany).Methods: Fifty-one eyes of 51 patients were included in the study. Flat keratometry (K) and steep K, vector component of astigmatism (Jackson cross-cylinder at 0° and 90° [J0] and Jackson cross-cylinder at 45° and 135° [J45]), anterior chamber depth, and axial length were compared using the three devices. Repeated measures analysis of variance was conducted to compare the mean values of the biometrics. Pearson correlation test was conducted to analyze the correlations of the measured values, and a Bland-Altman plot was used to assess the agreement between the three devices. The predicted intraocular lens power of each device was compared to the others using the SRK/T, Haigis, Barrett Universal II, and Kane formulas.Results: All K values measured using ANTERION were flatter than those of other instruments. However, good agreement was observed for flat K (ANTERION - OA-2000; 95% limits of agreement [LoA], 0.86 diopters [D]) and steep K (ANTERION - OA2000; 95% LoA, 0.93 D) and OA-2000 - IOLMaster 500 (95% LoA, 0.93 D). J0 and J45 vector components of astigmatism were not statistically different; however, the agreements were poor between the devices (95% LoA ≥1.97 D). Anterior chamber depth values of ANTERION and OA-2000 were interchangeable (95% LoA, 0.15 mm). The axial length showed a high agreement (95% LoA ≤0.17 mm) among the three devices. The predicted intraocular lens powers of the three devices were not interchangeable regardless of formulas (95% LoA ≥1.04 D).Conclusions: Significant differences in ocular biometrics were observed between ANTERION and the other two devices. This study demonstrated that only axial length showed good agreement among devices.

Purpose: To assess the comparability of ocular biometry measurements and refractive outcomes between ANTERION and IOL Master 700. Methods: This comparative prospective study was conducted from December 2020 to February 2021. A total of 225 patients who had cataracts were enrolled for the study and different parameters such as anterior keratometry (Steep K, Flat K) with axis, Sim K, central corneal thickness (CCT), aqueous depth (AQD), lens thickness (LT), and axial length (AL), white-to-white (WTW) were evaluated in IOL master 700 first and then with ANTERION. Finally, 203 patients completed the 6-week follow-up and the postoperative refraction was done at the 6 th week. To assess the agreement between the devices, intraclass coefficient (ICC) and Bland–Altman analysis with 95% limits of agreement (LoA) were used. To analyze the agreement for postoperative residual refractive error between the two devices, Kappa statistics were used. Results: The mean difference for steep K, flat K, and Sim K between ANTERION and IOL Master 700 were − 0.18 +/−0.26 D, −0.13+/− 0.28D, −0.15 +/−0.23, respectively. The CCT, ACD, and LT also showed excellent agreement (ICC > 0.9) but the similarity for the keratometry axis was not up to the mark (ICC = 0.794). For postoperative refractive outcomes, the Kappa value was 0.437, indicating moderate agreement. Conclusion: ANTERION showed a good agreement for the majority of parameters with IOLMaster 700 in measuring ocular biometry, except for the keratometry. The accuracy of the intraocular lens power calculations was clinically acceptable with both biometers though the IOL power given by ANTERION remained slightly on the hypermetropic side.
