The application of the Daytona ultra-widefield retinal imaging device in preoperative fundus examination before refractive surgery / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM: To evaluate the effectiveness of the Daytona ultra-widefield retinal imaging device in preoperative fundus examination before refractive surgery.<p>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.<p>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(<i>P</i><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(<i>P</i>=1.000).<p>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.
