摘　　要：目的研究植入可调节人工晶体1cu眼的调节能力。方法取39例48眼年龄相关性白内障患者,24眼植入Humanopstics 1cu可调节人工晶体,24眼植入AMOSI40NB单焦点人工晶体作为对照。术后3月检查患者最佳矫正视力,以及在最佳矫正视力基础上获得的最佳近视力、近点及调节幅度。结果3月后两组患者的最佳矫正远视力均有提高,可调节人工晶体组为0.75±0.15,对照组0.8±0.2,t=-0.980,P>0.05;可调节人工晶体1cu组获得更好的近视力,0.35±0.15,对照组0.20±0.09,t=4.201,P<0.001;主观近点:可调节组(56±9)cm;对照组(96±20)cm,t=-9.737,P<0.001;调节幅度:可调节组(1.3±0.4)D;对照组(0.3±0.2)D,t=10.954,P<0.001。结论植入可调节人工晶体可使患者获得一定程度的调节能力,同时具有单焦点人工晶体的优点。Objective A study on accommodative power of a new accommodative posterior chamber intraocular lens. Methods 24 eyes of 20 patients underwent phacoemulsification for cataracts and pcIOL implantation. Patients were examined postoperatively after 3 months, and results were compared with a control group of 24 eyes that received standard PMMA pcIOL. Results The results were （ lcu versus control pcIOL） ： best- corrected distance visual acuity 0.75 ± 0.15 versus 0.8 ±0.20, t = - 0.980, P 〉0.05; near visual acuity with best - distance correction 0.35 ± 0.15 versus 0.20 ± 0.09, t = 4.201, P 〈 0.001 ; subjective near point （56 ± 9） cm versus （96 ± 20） cm, t = - 9. 737, P〈 0.001 ; accommodative rang （1.30 ± 0.15） D versus （0.30±0.2） D, t= 10.954, P〈0.001. Conclusions Our results indicate eyes that underwent lcu PCIOL implantation can obtain accommodative power in some degree.
