目的 使用OQAS视觉质量分析系统(Optical Quality Analysis System,OQAS)对三种多焦点IOL (intraocular lens,IOL)植入术后进行IOL眼的视觉质量评估.方法 临床病例对照研究.选取2012年8月至12月在天津市眼科医院就诊的老年性白内障患者34例(34只眼).入选要求角膜散光度小于1.0 D,并排除中高度近视者.根据患者要求分别植入SN6AD1 IOL 11只眼、Acri.Lisa 366DIOL 11只眼和Tecnis ZMA00 IOL 12只眼的三种多焦点IOL.术后3个月,对所有IOL眼的视觉质量进行OQAS的测量.并对所有IOL眼客观散射指数(Objective Scatter Index,OSI)和MTF的截止频率(MTF Cut off)、斯特尔比率(Strehl ratio,SR)、对比度视力(Visual Acuity,VA)等视觉质量指标,进行比较.以同年龄正常对照组13名(13只眼)为标准,计算三组多焦点IOL眼与对照组对比度视力的比值进行比较.结果 术后3个月三组最佳矫正远视力均≥0.8;近视力不低于0.8的眼数分别为4只眼(4/11,36.3％)、4只眼(4/12,33.3％)和4只眼(4/11,36.3％),三组差异无统计学意义(P＞0.05).三组多焦点IOL眼的平均OSI进行比较,总平均值为(2.77±1.56),SN6AD1、ZMA00与Acri.Lisa 366 D三组患者平均OSI分别为(3.18±1.19)、(2.57±1.12)和(2.56±1.35),各组差异有统计学意义(F=1.592,P=0.042).三组患者平均MTF cutoff和SR比较,Acri.Lisa 366D略高于其他两组,但差异均无统计学意义(P =0.127).在不同对比度视力下,三组患者VA值差异均无统计学意义(P =0.325,0.268,0.222).三组多焦点IOL眼OQAS光学质量参数和不同对比度视力与对照组的比值均在0.5以上,并且ZMA00与Acri.Lisa 366D两组比值更接近于1.0.结论 通过OQAS视觉评估,三组多焦点IOL均具有较为稳定的视觉质量.OQAS对于多焦点IOL的视觉评估功能仍需大样本临床随机试验进一步验证.
目的 使用OQAS視覺質量分析繫統(Optical Quality Analysis System,OQAS)對三種多焦點IOL (intraocular lens,IOL)植入術後進行IOL眼的視覺質量評估.方法 臨床病例對照研究.選取2012年8月至12月在天津市眼科醫院就診的老年性白內障患者34例(34隻眼).入選要求角膜散光度小于1.0 D,併排除中高度近視者.根據患者要求分彆植入SN6AD1 IOL 11隻眼、Acri.Lisa 366DIOL 11隻眼和Tecnis ZMA00 IOL 12隻眼的三種多焦點IOL.術後3箇月,對所有IOL眼的視覺質量進行OQAS的測量.併對所有IOL眼客觀散射指數(Objective Scatter Index,OSI)和MTF的截止頻率(MTF Cut off)、斯特爾比率(Strehl ratio,SR)、對比度視力(Visual Acuity,VA)等視覺質量指標,進行比較.以同年齡正常對照組13名(13隻眼)為標準,計算三組多焦點IOL眼與對照組對比度視力的比值進行比較.結果 術後3箇月三組最佳矯正遠視力均≥0.8;近視力不低于0.8的眼數分彆為4隻眼(4/11,36.3％)、4隻眼(4/12,33.3％)和4隻眼(4/11,36.3％),三組差異無統計學意義(P＞0.05).三組多焦點IOL眼的平均OSI進行比較,總平均值為(2.77±1.56),SN6AD1、ZMA00與Acri.Lisa 366 D三組患者平均OSI分彆為(3.18±1.19)、(2.57±1.12)和(2.56±1.35),各組差異有統計學意義(F=1.592,P=0.042).三組患者平均MTF cutoff和SR比較,Acri.Lisa 366D略高于其他兩組,但差異均無統計學意義(P =0.127).在不同對比度視力下,三組患者VA值差異均無統計學意義(P =0.325,0.268,0.222).三組多焦點IOL眼OQAS光學質量參數和不同對比度視力與對照組的比值均在0.5以上,併且ZMA00與Acri.Lisa 366D兩組比值更接近于1.0.結論 通過OQAS視覺評估,三組多焦點IOL均具有較為穩定的視覺質量.OQAS對于多焦點IOL的視覺評估功能仍需大樣本臨床隨機試驗進一步驗證.

Objective To compare the visual and optical performance caused by different kinds of multifocal IOLs using OQAS system.Methods In a prospective non-radomized trial,34 eyes of patients for cataract surgery were offered SN6AD1,Acri.Lisa 366D,Tecnis ZMA00 three kinds of multifocal IOLs.Three months postoperatively,all of the subjects,straylight on the retina,MTF Cut off,Contrast Visual Acuity and Strehl ratio were measured with OQAS system.The normal group was used as the control group.Results The respective mean Objective Scatter Index measurements for SN6AD1,ZMA00 and Acri.Lisa 366D groups were 3.18±1.19,2.57±1.12 and 2.56±1.35,which showed statistically significant differences (F =1.592,P =0.042).The Acri.Lisa 366D groups with MTF cutoff and SR values were higher than the other groups,but no statistically significant differences (P =0.127).The mean Contrast Visual Acuity measurements for groups showed no statistically significant differences (P =0.325,0.268 and 0.222).Compared to the normal group,the visual and optical performance measurements for other groups had no significantly difference (P ＞0.05).Conclusions The three kinds of multifocal IOLs implantation are both safe and effective.The OQAS has been widely used to investigate optical quality in patients implanted with multifocal IOLs.
