3-dimentional lens densitometry measured with Scheimpflug imaging in eyes with cataract

本研究采用Scheimpflg散光密度计对近视检查环境和每个区域360度的晶状体密度进行了评估，并确定了它们与视觉表现的相关性。我们的结果表明，360度和每个区域的晶状体密度的量化可以提高视力的预测准确度。并利用光学仿真软件验证了折射率、散射率和透光率对视网膜图像质量的影响。应用Scheimpflug密度计的三维晶状体密度测量有助于白内障的随访和治疗/预防药物的定量，并可能成为预测白内障患者视力的一种潜在工具。

The study assessedthe crystalline lens density covering 360 degrees in pupil diameterclose to environment of examination of visual performance and every area using the Scheimpflug densitometry, and to determine their correlation with visual performance.Our results suggest that the quantitation of lens density covering 360 degrees and every area improve predictive accuracyof visual acuity. Also, weconfirmed the effects of refractive index, scatter, and light transmittance on retinal image qualityusing optical simulation software. The 3-D lens densitometry using the Scheimpflug densitometry could be helpful for follow-up of cataractsand quantitation of curative/preventive drug, and could be a potential tool for prediction of visualperformancein cataract patients.
