摘要
目的:探讨1CU可调节人工晶状体植入眼内后术眼拟调节能力。方法:通过对2003-06至今我院行白内障超声乳化联合可调节人工晶状体1CU术后对术眼裸眼远、近视力,矫正视力,矫正远视力下的近视力进行测量,并运用主觉近点法、离交法、动态视网膜检影法以及A超测量10g/L匹罗卡品点眼前后前房深度,检测术眼拟调节能力,同期以单焦人工晶状体Acrysof作为临床对比,评价可调节人工晶状体1CU临床应用效果。结果:1CU组的裸眼近视力和矫正远视力下的近视力好于Acrysof组;带状光检影测量1CU组的调节力为0.99±0.45D,Acrysof组的调节力为0.25±0.22D,两组差异有显著性意义(t=5.623,P<0.05);主觉近点法测量1CU组的调节力为1.60±0.55D,Acrysof组的调节力为0.42±0.22D,两组差异有显著性意义(t=2.147,P<0.05);离焦法测量1CU组的调节力为1.46±0.52D,Acrysof组的调节力为0.52±0.35D,两组差异有显著性意义(t=2.647,P<0.05);滴用匹罗卡品眼药水后分别测量1CU组和Acrysof组前房深度(ACD)变化,两组比较有显著性差异(t=4.374,P<0.05)。结论:1CU可调节人工晶状体可以明显提高近视力,使白内障患者术后获得一定的调节力。
AIM： To evaluate the clinical outcome after implantation of the new 1CU accommodating intraocular lens in cataract patients.
METHODS： Since .July 2003, patients with age-related cataract admitted in our hospital underwent phacoemulsification and were implanted with 1CU IOL, and the uncorrected and corrected distance and near visual acuity, distance corrected near acuity were observed. The following methods were used to measure accommodation： dynamic with objective techniques （streak retinoscopy） and subjective techniques （subjective near point, defocusing）; static with pharmacologic stimulation after pilocarpine 1% eyedrops indirectly （change in the anterior chamber depth）. The results were compared to those of foldable acrylic lOt. （Acrysof, Alcon）.
RESULTS： The near visual acuity and distance corrected near acuity of 1CU group were better than those of Acrysof group. Accommodation amplitudes were 0.99± 0.45D and 0. 25± 0.22D measured by streak retinoscopy （t=5.623, P〈0.05）, 1.60± 0.55D and 0.42± 0.22D by subjective near point （t=2. 147, P〈0.05）, and 1.46± 0.52D and 0.52± 0.35D by defocusing （t=2.647, P〈0.05） in the study and control study groups, respectively. The mean ACD was 0.63± 0.15mm and 0.18± 0. 12mm after pilocarpine 1% eyedrops, respectively.
CONCLUSION： 1CU accommodating IOL can provide good near visual acuity and accommodation amplitude for cataract patients.
