目的：评价Daytona超广角眼底成像系统对屈光手术术前眼底病变的检查效果。

方法：连续检查拟接受屈光手术的患者312例624眼，分别在自然瞳孔下行Daytona超广角眼底成像系统检查和散瞳后裂隙灯下前置镜结合三面镜检查，比较两种方法检查用时和检出的病变类型和检出率。

结果：Daytona超广角眼底成像系统检查的平均时间5.38±1.25min，裂隙灯前置镜检查平均时间7.25±3.23min，差异有统计学意义(P<0.01)。Daytona检出有眼底病变的69例107眼，检出率17.1%，检出病变126处； 前置镜结合三面镜检出70例108眼，检出率17.3%，检出病变129处。两种方法检出率的一致性差异无统计学意义(P=1.000)。

结论：Daytona具有免散瞳、非接触、检查快捷、超广角等优点，用于眼底病变的检查，效果可靠，可以提升诊疗效率。

METHODS: A consecutive series of 624 eyes in 312 patients intended to performing refractive surgery with myopia were examined fundus by the Daytona ultra-widefield retinal imaging device before dilating pupil. After dilating pupil, the non-contact slit lamp lenses and three-mirror contact lens were used to examine fundus again.

RESULTS: Average examination time of the Daytona and non-contact slit lamp lenses was 5.38±1.25min and 7.25±3.23min respectively, there was no statistical significant difference(P<0.001). The Daytona detected peripheral retinal pathology in 107 eyes(17.1%)and the non-contact slit lamp lenses detected peripheral retinal pathology in 108 eyes(17.3%), 126 lesions were detected and there was no statistical significant difference between the two methods(P=1.000).

CONCLUSION: The Daytona has non-contact, shorter time and ultra-widefield view of the retina which is a reliable method in examining the retinal pathology without mydriasis.
