目的:使用IOLMaster700预测白内障手术后的人工晶状体位置,并与从眼前节分析系统获得的结果进行比较,探索相关的眼部参数(Sirius,CSOInc,佛罗伦萨意大利)。
方法:共98例(106只眼)纳入回顾性研究。使用IOLMaster700获得术后人工晶状体位置,并使用AdobeIllustrator软件进行测量。应用相关性分析和线性回归分析研究术后人工晶状体(ALP)的实际位置与眼部参数的相关性。此外,Bland-Altman一致性分析用于比较使用IOLMaster700生物测量获得的预测人工晶状体位置(ALPi)中任何两个之间的一致性。使用眼前节分析系统计算的预测人工晶状体位置(ALP),或ALP。
结果:眼部参数,包括术前前房深度,透镜厚度,轴向长度,白色到白色,单因素分析显示术后屈光不正与白内障术后ALP相关(P<0.05)。然而,在多元线性回归中,只有前三个变量与ALP相关。与眼前节分析得出的方程相比,IOLMaster700生物测量的方程提供了更好的拟合.一致性分析结果表明,ALP,ALPi,和ALP达成了很好的协议。
结论:IOLMaster700生物测量有助于预测手术后的人工晶状体位置,并且其准确性优于眼前节分析系统提供的准确性。
OBJECTIVE: Predict intraocular lens position after cataract surgery using the IOL Master 700 and explore the associated ocular parameters compared with the results obtained from the anterior segment analysis system (Sirius, CSO Inc, Florence, Italy).
METHODS: A total of 98 patients (106 eyes) were included in the retrospective study. The postoperative intraocular lens position was obtained using the IOL Master 700 and measured using Adobe Illustrator software. Correlation analysis and linear regression analysis were applied to study the correlation between the actual position of the postoperative intraocular lens (ALP) and the ocular parameters. In addition, Bland-Altman consistency analysis was used to compare the consistency between any two among the predicted intraocular lens position (ALPi) obtained using IOL Master 700 biometry, the predicted artificial lens position (ALPs) calculated using the anterior segment analysis system, or the ALP.
RESULTS: Ocular parameters, including preoperative anterior chamber depth, lens thickness, axial length, white-to-white, and postoperative refractive error were all correlated with ALP after cataract surgery (P < 0.05) using univariate analysis. However, in multivariate linear regression, only the first three variables were correlated with ALP. Compared with the equation obtained by the anterior segment analysis, the equation from IOL Master 700 biometry provided a better fit. The results of the consistency analysis showed that ALP, ALPi, and ALPs were in good agreement.
CONCLUSIONS: IOL Master 700 biometry can help predict intraocular lens position after surgery, and its accuracy is better than that provided by the anterior segment analysis system.
