| Research Abstract |
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.
