目的 比较两种不同攀设计的非球面人工晶状体在囊袋内植入后伪调节力的差异.方法 临床病例对照研究.选择2012年5～12月在延边大学附属医院眼科行超声乳化白内障摘除联合人工晶状体植入术的老年性白内障患者82例(126只眼),应用随机数字表法髓机分为两组,SN60WF为IQ组植入“L”形Acrysof IQ SN60WF (Alcon Laboratories,Fort Worth,Texas,USA)人工晶状体(59只眼);Adapt AO为AO组植入一体四点Akreos Adapt AO (Bausch&Lomb,Rochester,NY,USA)人工晶状体(67只眼).采用眼前段光学相干断层扫描仪(AS-OCT)实时测量人工晶状体眼在诱导调节状态下的调节幅度、前房深度及瞳孔直径等变化.结果 两组非球面人工晶状体植入术后平均伪调节力:AO组为(1.09±0.51)D,IQ组为(1.26±0.34)D.两组差异有统计学意义(t=2.314,P=0.041).IQ组前房深度变化值为(0.29±0.12) mm,AO组为(0.21±0.15) mm,两组差异有统计学意义(t=2.642,P=0.034).IQ组瞳孔直径变化值为(0.52±0.20) mm,AO组为(0.49±0.16) mm,两组差异无统计学意义(t=0.946,P=0.541).两组的瞳孔直径与伪调节力,差异有统计学意义(r=-0.651,P=0.024).结论 超声乳化白内障吸除联合折叠式单焦点非球面人工晶状体植入术后存在一定的伪调节力,不同攀设计可产生伪调节力的差异.AS-OCT是动态检测人工晶状体眼伪调节过程中眼前段结构的变化的一种有效方法.
目的 比較兩種不同攀設計的非毬麵人工晶狀體在囊袋內植入後偽調節力的差異.方法 臨床病例對照研究.選擇2012年5～12月在延邊大學附屬醫院眼科行超聲乳化白內障摘除聯閤人工晶狀體植入術的老年性白內障患者82例(126隻眼),應用隨機數字錶法髓機分為兩組,SN60WF為IQ組植入“L”形Acrysof IQ SN60WF (Alcon Laboratories,Fort Worth,Texas,USA)人工晶狀體(59隻眼);Adapt AO為AO組植入一體四點Akreos Adapt AO (Bausch&Lomb,Rochester,NY,USA)人工晶狀體(67隻眼).採用眼前段光學相榦斷層掃描儀(AS-OCT)實時測量人工晶狀體眼在誘導調節狀態下的調節幅度、前房深度及瞳孔直徑等變化.結果 兩組非毬麵人工晶狀體植入術後平均偽調節力:AO組為(1.09±0.51)D,IQ組為(1.26±0.34)D.兩組差異有統計學意義(t=2.314,P=0.041).IQ組前房深度變化值為(0.29±0.12) mm,AO組為(0.21±0.15) mm,兩組差異有統計學意義(t=2.642,P=0.034).IQ組瞳孔直徑變化值為(0.52±0.20) mm,AO組為(0.49±0.16) mm,兩組差異無統計學意義(t=0.946,P=0.541).兩組的瞳孔直徑與偽調節力,差異有統計學意義(r=-0.651,P=0.024).結論 超聲乳化白內障吸除聯閤摺疊式單焦點非毬麵人工晶狀體植入術後存在一定的偽調節力,不同攀設計可產生偽調節力的差異.AS-OCT是動態檢測人工晶狀體眼偽調節過程中眼前段結構的變化的一種有效方法.

Objective To compare the pseudophakic accommodation of different designs of aspheric intraocular lens (IOL) in phacoemulsification.Methods One hundred and twenty-six eyes with cataract surgery were randomized into 2 groups:an Acrysof IQ SN60WF (Alcon Laboratories,Fort Worth,Texas,USA) IOL group (59 eyes) and Akreos Adapt AO (Bausch & Lomb.,Rochester,NY,USA)IOL group (67 eyes).Patients were examined using anterior segment optical coherence tomography (AS-OCT),including anterior chamber depth (ACD),pupil diameter,and amplitude of pseudophakic accommodation,preoperatively and 6 months postoperatively.Results The IQ IOLs and AO IOLs group of mean pseudophakic accommodation was (1.26±0.34)D and (1.09±0.51)D,respectively,there was statistically significantly different (t =2.314,P =0.041).The mean pupil diameter measurements for IQ group and AO IOL group were (0.52±0.20)mm and (0.49±0.16)mm,respectively,which showed no statistically significant differences (t =0.946,P =0.541).The amplitude of pseudophakic accommodation was negative correlated with pupil diameter (r =-0.651,P =0.024).Conclusions The movement of aspheric IOLs in eyes after cataract surgery is an important mechanism for attaining good near vision without additional correction,2-point haptic design IOLs provide better pseudophakic accommodation than that of Four-point haptic designs.
