目的：比较Pentacam AXL与IOL Master 700对白内障患者术前眼部生物学参数的比较。

方法：前瞻性研究。选取2024年5月至2024年12月我院收治的拟行白内障超声乳化联合人工晶状体(IOL)植入术治疗的白内障患者150例150眼。术前采用IOL Master 700、Pentacam AXL分别测量眼轴长度(AL)，角膜曲率(K1，K2，Km)，前房深度(ACD)，角膜横径(WTW)。比较两种仪器测量结果的差异性和一致性。

结果：两种仪器测量术眼AL、K1、K2、Km、ACD及WTW比较均无差异(均P>0.05)。Spearman相关性分析显示两种仪器测量术眼AL、K1、K2、Km、ACD及WTW均正相关(均P<0.001)。Bland-Altman分析显示，Pentacam AXL与IOL Master 700测量术眼AL、K1、K2、Km、ACD及WTW分别有5/150(3.3%)、7/150(4.7%)、4/150(2.7%)、5/150(3.3%)、0个点位于95%LoA外，均小于5%，提示一致性较好。

结论：Pentacam AXL与IOL Master 700在白内障超声乳化联合IOL植入术前AL、K1、K2、Km、ACD及WTW的测量数据均无显著性差异，且具有较好的相关性及一致性，两种仪器可相互替代使用。

METHODS:Prospective study. A total of 150 patients(150 eyes)with cataracts who were treated in our hospital from May to December 2024 were selected. The IOL Master 700 and Pentacam AXL were preoperatively used to measure axial length(AL), corneal curvature(K1, K2 and Km), anterior chamber depth(ACD), and white-to-white(WTW). The difference and consistency of the results of the two instruments were compared.

RESULTS: There was no significant difference between the two instruments in the AL, K1, K2, Km, ACD, and WTW(all P>0.05). The Spearman correlation analysis showed that the two instruments positively correlated with the AL, K1, K2, Km, ACD and WTW of the operated eye(all P<0.001). The Bland-Altman analysis showed that for the Pentacam AXL and IOL Master 700, there were 5/150(3.3%), 7/150(4.7%), 4/150(2.7%), 5/150(3.3%), and 0 points outside the 95%LoA for the AL, K1, K2, Km, ACD, and WTW of the examined eyes, respectively, with all of these values less than 5%, indicating good consistency.

CONCLUSION:The AL, K1, K2, Km, ACD and WTW of Pentacam AXL and IOL Master 700 in cataract patients before cataract phacoemulsification combined with IOL implantation show no significant differences, and have good correlation and consistency. The two instruments can be used interchangeably.
