Correlation Analysis Of Lens Dysfunction Index And Visual Functional Index

Objective:To analyze the correlation between Dysfunctional Lens Index(DLI)and other functional indexes.Methods:From October 2016 to May 2017,patients with early cataract who were treated in Ophthalmology Clinic of our hospital,the best corrected visual acuity was≥0.6,slit lamp,i-Trace,OQAS,C-Quant and OPD-Scan Ⅲ and Pentacam and measured DLI,OSI,Log(S),total high order aberrations of the lens and lens coma,trefoil aberration,spherical aberration,lens density and other indexes.Pearson correlation analysis was used to compare DLI values with other indexes.Results:The lens dysfunction index and subjective and objective visual quality included objective scattering index(r =-0.321,P = 0.004),intraocular light scattering(r =-0.329,P= 0.003),higher order aberrations(r =-0.272,P= 0.015),lens coma aberration(r =-0.259,P = 0.021),trefoil aberration(r =-0.322,P=0.004),spherical aberration(r=-0.349,P=0.001).There was a negative correlation between the lens dysfunction index and the average density of lens(r =-0.312,P = 0.005),which had statistical significance.Conclusion:The lens dysfunction index combined visual quality evaluation indicators can be used to evaluate the visual function of patients with early lens crystalline,which can provide better evidence for refractive cataract surgery.
