目的：比较评估A超及IOL Master在硅油眼患者眼轴长度测量的精确性，探讨IOL Master在硅油眼人工晶状体度数计算中的临床应用价值。方法：分析我院2012-06/12间收治的硅油眼白内障手术患者30例30眼，分别用接触式A超及IOL Master测量术前、术后眼轴长度比较两者之间差异。并将术前 IOL Master测量自动获取IOL度数后预估患眼屈光状态与术后1 mo复查患者屈光状态（等效球镜度数）行统计学分析。结果：A超与术前IOL Master 测量眼轴有显著性差异，使用IOL Master测量术前、术后眼轴无显著差异，术后使用A超及IOL Master测量眼轴之间无显著性差异。采用IOL Master术前测量眼轴所得人工晶状体度数植入人工晶状体术后屈光状态与术前预估无明显差异。结论：IOL Master测量眼轴较A超有明显优越性，但对于某些不能使用IOL Master测量的病例仍需结合A超等其他测量方法辅助测量。

AIM: To evaluate and compare the accuracy of IOL-Master and A-scan in measuring the axial length of silicone oil-filled eyes, and to explore the clinical value of IOL-Master in calculating intraocular lens diopter of the silicone oil-filled eyes. METHODS: An analysis was made of 30 patients ( 30 eyes ) who received cataract surgery combined with silicone oil removal in our hospital from June 2012 to December 2012. Before the operation and one month afterwards, the axial length was measured by both IOL-Master and A-scan, and all the results were divided into two groups:A-scan group and IOL-Master group.Then we used IOL-Master to calculate the intraocular lens diopter and to estimate the postoperative refraction. Postoperative refraction was measured one month after operation and compared with the preoperative estimates. RESULTS: Before silicon oil removal, there was significant difference between the axial lengths obtained by IOL-Master and those by A-scan, with the former much smaller than the latter.After the operation, there was no significant difference between the axial lengths obtained by the two methods.The axial lengths measured by IOL -Master before and after operation were not significantly different. No significant difference was observed between the postoperative refraction and the preoperative estimates, either. CONCLUSION:IOL-Master is a more preferable method to measure axial length than A-scan.However, in cases where IOL-Master cannot be applied, A-scan together with other methods should be used.
