摘要：

目的·比较Lenstar LS900与Tomey EM-3000测量玻璃体切除术后无晶体眼角膜中央厚度的精确性和一致性。方法·玻璃体切除术后3个月以上的患者共54例（55眼），所有术眼均为无晶体眼。分别按照眼轴长度分为3组：A组（眼轴长度≥26 mm）、B组（24 mm≤眼轴长度＜26 mm）、C组（眼轴长度＜24 mm），或者分为硅油组（26眼）和非硅油组（29眼），再按照眼轴长度分3组。采用Lenstar LS900与 Tomey EM-3000眼前节分析系统分别测量角膜中央厚度，并对所得数据进行统计学分析。结果·Lenstar LS900测量的角膜中央厚度的平均值为（550.44±32.03）μm，Tomey EM-3000测量的角膜中央厚度的平均值为（547.58±34.29）μm，两者之间差异有统计学意义（P<0.01）；但是在A组、B组、C组中，2种方法测量的角膜中央厚度的差异均无统计学意义（P>0.05）；比较硅油组和非硅油组，2种方法测量的角膜中央厚度差异无统计学意义（P>0.05）,仅在非硅油组中的A 组中，2种方法测量的角膜中央厚度的差异存在统计学意义（P<0.05）。2种方法测量的角膜中央厚度值之间存在线性相关（r=0.957，P<0.01）；测量差值的95%一致性界限范围为（-16.77 μm，22.47 μm），92.7%（51/55）的测量值在一致性界限内。结论·Lenstar LS900 测量的角膜中央厚度值略大于Tomey EM-3000，但两者之间存在正相关性，具有一致性，均可以用于玻璃体切除术后的角膜中央厚度的测量。

Abstract:

Objective·To compare the accuracy and consistency between Lenstar LS900 and Tomey EM-3000 for measuring central corneal thickness after vitrectomy. Methods·Fifty-four patients (55 aphakic eyes) who had undergone post-vitrectomy for at least three months were assigned to three groups based on the axial length, i.e. group A (axial length≥26 mm), group B (axial length between 24 mm and 26 mm), and group C (axial length＜24 mm ). The patients were also assigned to the silicone oil-filled eye group (26 eyes) and the non-silicone oil-filled eye group (29 eyes), and then each group was assigned to three groups according to the axial length. The central corneal thickness was measured using Lenstar LS900 and Tomey EM-3000 analyzer and the data were statistically analyzed. Results·The mean central corneal thickness values measured by Lenstar LS900 and Tomey EM-3000 were (550.44±32.03) μm and (547.58±34.29) μm, respectively and the difference was statistically significant (P<0.01). But the differences in mean central corneal thickness values between the two methods in group A, group B, or group C were not statistically significant (P>0.05). The differences in mean central corneal thickness values between the two methods in the silicone oil-filled eye group or the non-silicone oil-filled eye group were not statistically significant (P>0.05). Only the differences in mean central corneal thickness values between the two methods in group A of the non-silicone oil-filled eye group were statistically significant (P<0.05). Mean central corneal thickness values measured by the two methods were linearly correlated (r=0.957, P<0.01). The width of the 95% limit of agreement ranged from -16.77 μm to 22.47 μm, containing 92.7% (51/55) measurements. Conclusion·The central corneal thickness measured by Lenstar LS900 is slightly larger than that measured by Tomey EM-3000. The two methods are positively correlated and consistent, and both of them can be used to measure the central corneal thickness after vitrectomy.
