摘　　要：目的:初步评估非球面人工晶状体植入术后早期视功能情况。方法:将88例(91只眼)白内障患者随机分为AcrySofIQ(SN60WF)、KS-3Ai和AcrySof Natural(SN60AT)人工晶状体组。观察患者术后1d、1周和1月最佳矫正视力和术后1月对比敏感度及主观视觉等视功能情况。结果:术后第1天KS-3Ai组最佳矫正视力明显优于其余两组(P﹤0.05),术后1周、1月三组最佳矫正视力差异均无显著性意义(P>0.05)。AcrySofRIQ和KS-3Ai组中、低频区对比敏感度在瞳孔直径2.5mm～4.0mm及5.0mm～6.0mm时均优于AcrySof Natural组(P﹤0.05),而AcrySofRIQ和KS-3Ai两组比较无显著性意义(P﹥0.05)。采用VF/QOL问卷调查显示AcrySofIQ和KS-3Ai组患者的总体满意度好。结论:非球面人工晶状体能明显提高白内障患者术后对比敏感度,改善患者术后视觉质量。Purpose ： To initially evaluate the early visual function after implantation with aspheric intraocular lens Methods： Eighty-eight subjects （91 eyes） were divided randomly into three groups： AcrySof IQ （SN60WF） group, KS-3Ai group and AerySof Natural （SN60AT） group. Best corrected visual acuity was observed 1 day, 1 week and 1 month postoperatively, while contrast sensitivity and subjective vision were observed 1 month later. Results： Best corrected visual acuity was obviously better in KS-3Ai group than in the other groups 1 day postoperatively （P 〈 0.05）, but no significant difference was found 1 week and 1 month later among the groups （P 〉 0.05）. When the pupil diameter was in 2.5 to 4.0 mm and 5.0 to 6.0mm, AerySof IQ and KS-3Ai groups were better than the AcrySof Natural group in the low and middle spatial frequency （P 〈 0.05）. However, there was no significant difference between AcrySof IQ and KS-3Ai groups （P 〉 0.05）. VF/QOL questionnaire was obtained, showing that implantation with AcrySof IQ and KS-3Ai satisfied patients preferably. Conclusions： Aspherie intraoeular lens can greatly improve patients＇ contrast sensitivity and quality of vision. Eye Science 2007; 23 ： 43-47.
