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。
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.
