Pentacam Scheimpflug成像测量晶状体密度与torsional超声乳化参数间的关系
目的:评价运用Pentacam Scheimpflug成像测量晶状体核密度与torsinal超声乳化动力学参数(如:运用于老年核性白内障患者的超声能量水平、液体留存时间及液体量)间的关系。方法:此研究为前瞻性双盲研究。瞳孔扩大后运用Pentacam Scheimpflug 成像进行测量。白内障的等级由pentacam核密度测定法[ pentacam nucleus densitometry, PND;又名Pentacam核分段( Pentacam nucleus staging, PNS)软件]自主分为1到5个等级。超声乳化术后,自动在Infiniti Ozil IP超声乳化系统监视器上计算并...

Summary: | 目的:评价运用Pentacam Scheimpflug成像测量晶状体核密度与torsinal超声乳化动力学参数(如:运用于老年核性白内障患者的超声能量水平、液体留存时间及液体量)间的关系。方法:此研究为前瞻性双盲研究。瞳孔扩大后运用Pentacam Scheimpflug 成像进行测量。白内障的等级由pentacam核密度测定法[ pentacam nucleus densitometry, PND;又名Pentacam核分段( Pentacam nucleus staging, PNS)软件]自主分为1到5个等级。超声乳化术后,自动在Infiniti Ozil IP超声乳化系统监视器上计算并显示总超声( U/S)时间、累计耗散能、Torsional U/S时间以及估算液体的使用情况。组间差异运用单因素方差分析( ANOVA )进行评定,多组分析运用Tamhane测试法,PND测量的晶状体密度与torsinal超声乳化动力学参数间的关系运用Spearman相关分析进行评定。界定P〈0.05时具有统计学意义。结果:此项研究包括125例患者(125眼),平均年龄为69.7±9.4岁(范围:48~88岁),其中61例男性、64例女性。 U/S总时间、torsional U/S时间、CDE及估算液体使用情况的范围分别为0.70~158.9s,0.70~158.5s,0.11~42.65和21~98mL. PND组间数据有统计学差异。评估超声乳化动力学参数与PND数据间关系后得出PND数据与总超声时间( r=0.767; P〈0.01)、torsional超声时间(r=0.767;P〈0.01)、CDE(r=0.758; P〈0.01)及液体使用量(r=0.602;P〈0.01)均有显著相关性。结论:白内障手术前运用PND评分法获得核密度的客观程度可为超声乳化术中的参数提供可靠的预见性。因此,对每一位患者进行每一单项超声乳化参数的评估,有助于降低超声乳化能量的使用量,减少内皮细胞丢失和类固醇的使用,加速视力的恢复。 |

METHODS: This was a prospective observer-masked study. Pentacam Scheimpflug imaging was performed following pupil dilation. The cataracts were automatically graded from 1 to 5 using pentacam nucleus densitometry (PND), also known as Pentacam nucleus staging (PNS) software by the same observer. After phacoemulsification, total Ultrasound ( U/S ) time, Cumulative dissipated energy ( CDE ) , Torsional U/S time, and Estimated |
