摘要
目的:比较Tetraflex和1-CU可调节晶状体植入术后早期的临床效果差异。方法:选择2010年6月至2011年5月在我院接受白内障超声乳化联合植入人工晶体患者,分别分组为1-CU组和Tetraflex组。分别于术后1周、1个月、3个月行眼科检查,检查裸眼远视力及最佳矫正远视力、近视力及远视力矫正后的近视力,采用主观移近法和动态检影法测量调节力。结果:最佳矫正远视力于1周、1个月、3个月时2组间均无统计学差异(P>0.05),但随着时间的推移,最佳矫正远视力也越来越好。2组患者裸眼近视力以及最佳远矫正视力下的近视力在3个月时均呈现下降趋势(P<0.05)。1-CU组于1周、1个月和3个月时的裸眼远视力均高于Tetraflex组,差异具有统计学意义(P<0.05)。Tetraflex组于1周、1个月和3个月时的裸眼近视力均高于1-CU组,差异具有统计学意义(P<0.05)。结论:2种类型人工晶体均能使患者获得良好的最佳矫正远视力下的近视力,Tetraflex型可提供患者更好的裸眼近视力,1-CU型可提供患者更好的裸眼远视力。两型人工晶体均可增加患者假晶体眼的伪调节力,改善患者的主观视功能。然而,对于可调节晶状体的远期效果仍需要进一步的研究。
Objective ：To evaluate the clinical efficacy after implantation of the 1-CU accommodating intraocular lens and Tetraflex accommodating intraocular lens in cataract patients. Methocls：77 age-related cataract patients（80 eyes） were divided into two groups： 1-CU group included 38 patients（40 eyes）, and Tetraflex group included 39 patients（40 eyes）. All the patients accepted phacoemulsification and IOL implantation. Patients were examined for the uncorrected and corrected distant visual acuity, uncorrected near visual acuity, and the distance corrected near visual acuity at 1 week, 1 month, and 3 months after the surgery, and the amplitude of accommodation by 2 different methods （the dynamic retinoscopy method and near point method）at 1 week, 1 month,and 3 months after the surgery. Results ：There were no significant differences of the corrected near visual acuity at 1 week, 1 month, and 3 months after the surgery between two groups（P〉0.05）,but the corrected near visual acuity became better as time went on. The uncorrected near visual acuity and the distance corrected near visual acuity became worse at 3 months after surgery（P〈0.05）. Both groups had good distance corrected near visual acuity, and there were no significant differences of the distance corrected near visual acuity between the two groups（P〉0.05）. The uncorrected distant visual acuity at 1 week, 1 month,and 3 months after the surgery of 1-CU group was significantly better than that of Tetraflex group （P〈0.05）. The uncorrected neat visual acuity at 1 week, 1 month, and 3 months after the surgery of Tetraflex group were significantly better than that of 1-CU group（P〈0.05）. There were no significant differences of amplitude of accommodation between the two groups（P〉0.05）,but both the amplitude of accommodation became worse at 3 months after surgery. Conclusion：Both two IOL can provide good distance corrected near visual acuity.1-CU group have better uncorrected distant visual acuity, and Tetraflex
