晶状体密度与超声乳化动力学参数的量化关系
Correlation of lens density and phacodynamics parameters in phacoemulsification
摘要
Abstract
Objective To evaluate the correlation of lens density (LD) measured by opacity lensmeter (OLM) and Pentacam with phacodynamics in patients with age-related nuclear cataract.Methods A prospective study was conducted in 78 patients (78 eyes) with age-related nuclear cataract.The lens density was measured with OLM and Pentacam respectively before operation,and the phacoemulsification kinetic parameters in phacoemulsification,including ultrasound time (UST),cumulated dissipated energy (CDE) and balanced salt solution (BSS) usage,were recorded for the analysis of the correlations of LD values with phacodynamics.Results LD measured by OLM and Pentacam was 32.83 ± 14.41 and 15.26 ±5.82,respectively.LD from OLM and Pentacam was positively correlated with both UST (r =0.645,0.807,respectively;both P ＜ 0.05)and CDE (r =0.669,0.828,respectively;both P ＜ 0.05).UST and CDE were more strongly correlated with LD from Pentacam than from OLM (Z =2.153,2.283;both P ＜0.05).Conclusion LD from both OLM and Pentacam are correlated with UST and CDE,and a stronger correlation is observed in Pentacam than OLM.关键词
