    摘要:

    目的:比较Orbscan眼前节分析系统与光学相干生物测量仪IOLMaster测量角膜曲率的差异。方法:我院2010-09/12屈光手术前近视患者68例135眼,排除近期隐形眼镜配戴史、严重干眼患者、曾经进行过角膜手术者以及其他眼部器质性病变者,其中男46例91眼,女22例44眼,同时用两种方法测量角膜曲率,进行临床比较。结果:Orbscan眼前节分析系统、IOLMaster两种仪器测量角膜曲率结果分别为43.4637±1.4188,43.6952±1.3676D。两组间比较,差异无统计学意义(P>0.05)。结论:Orbscan眼前节分析系统与IOLMaster对近视患者角膜曲率检查结果无统计学差异。IOLMaster用于屈光手术术前角膜曲率检查评估有一定价值。

    Abstract:

    AIM:To analyze keratometric readings obtained from Orbscan topography system and IOLMaster in myopia patients.METHODS:The corneal curvature were measured with Orbscan topography system and IOLMaster respectively in 68 cases(135 eyes) subjects aged 18-41 years old.There were 46 male(91 eyes) and 22 female(44 eyes)subjects.The results were compared.RESULTS:The average corneal curvature measured by Orbscan topography system and IOLMaster were 43.4637±1.4188 and 43.6952±1.3676D.The measurement obtained from Orbscan topography system was lower than that from IOLMaster,There is no statistical difference between the two methods.CONCLUSION:Corneal curvature abtained from IOLMaster showed no significant difference than that from Orbscan system.It is a clinically useful tool in eveluating corneal surface curvature.
