Abstract：
BACKGROUND: To evaluate the axial length acquisition success rates and agreement between various biometric parameters obtained with different biometers in dense cataracts.
METHODS: Fifty-one eyes were measured using Anterion®, Argos® and IOLMaster® 700 swept-source optical coherence tomography (SS-OCT) biometers, a Pentacam® AXL partial coherence interferometry (PCI) biometer, and an OcuScan® RxP ultrasound biometer. We measured keratometry (K1, flattest keratometry and K2, steepest keratometry), white-to-white (WTW), anterior chamber depth (ACD), lens thickness (LT) and axial length. Cataracts were classified according to the Lens Opacities Classification System III grading system, the dysfunctional lens index (DLI) and Pentacam® nucleus staging (PNS) metrics. Percentage of acquisition success rate and a Bland-Altman analysis for the agreement between biometers were calculated.
RESULTS: The mean LOCS III score was 3.63 ± 0.92, the mean DLI was 2.95 ± 1.30 and the mean PNS was 2.36 ± 1.20. The acquisition success rates for the Anterion®, Argos®, IOLMaster® 700, Pentacam® AXL and OcuScan® RxP biometers were 94.12%, 100%, 98.04%, 60.78% and 100%, respectively. There were significant differences in the success rates between biometers (P = 0.014). There were statistically significant differences between biometers for all parameters evaluated (P < 0.05). The range of the limit of agreement (LoA) for all comparisons of K1 and K2 were > 1.00 D. The LoA for WTW ranged from 0.095 to 1.050 mm. The LoA for ACD and LT ranged from 0.307 to 0.114 mm and from 0.378 to 0.108 mm, respectively. The LoA for axial length ranged from 0.129 to 2.378 mm.
CONCLUSIONS: Among optical biometers, those based on SS-OCT technology are more successful at measuring axial length in eyes with dense cataracts.

摘要：
背景：为了评估在致密性白内障中使用不同生物测定仪获得的各种生物特征参数之间的轴向长度采集成功率和一致性。
方法：使用Anterion®测量51只眼，Argos®和IOLMaster®700扫频源光学相干断层扫描(SS-OCT)生物测定仪,Pentacam®AXL部分相干干涉(PCI)生物测量仪，和OcuScan®RxP超声生物仪。我们测量了角膜角化术（K1，最平坦的角膜角化术和K2，最陡峭的角膜角化术），白色到白色(WTW),前房深度（ACD），透镜厚度（LT）和轴向长度。白内障根据晶状体混浊分类系统III分级系统进行分类，功能失调的晶状体指数（DLI）和Pentacam®核分期（PNS）指标。计算了获取成功率的百分比和Bland-Altman分析，以确定生物测定之间的一致性。
结果：平均LOCSIII评分为3.63±0.92，平均DLI为2.95±1.30，平均PNS为2.36±1.20。Anterion®的收购成功率，Argos®,IOLMaster®700、Pentacam®AXL和OcuScan®RxP生物测定为94.12%，100%,98.04%,60.78%和100%，分别。生物测定的成功率差异有统计学意义(P=0.014)。所有评估参数的生物指标之间存在统计学差异（P<0.05）。K1和K2的所有比较的一致性极限(LoA)的范围>1.00D。WTW的LoA范围为0.095至1.050mm。ACD和LT的LoA范围为0.307至0.114mm和0.378至0.108mm，分别。轴向长度的LoA范围为0.129至2.378mm。
结论：在光学生物计中，基于SS-OCT技术的方法在测量致密性白内障眼的眼轴长度方面更为成功.
