摘要 目的:评价 Tetraflex 可调节人工晶状体植入术后 1a 的临 床效果。 方法:纳入研究组 23 例,均为老年性白内障患者,所有患 者均在我院确诊并行白内障超声乳化摘除联合 Tetraflex 可调节人工晶状体植入术。 术后 12mo 复诊时,分别记录 患者的裸眼远视力、裸眼近视力、脱镜率、患者满意度以及 异常视觉出现情况。 另外,重点记录前、后囊膜的混浊情 况。 对照组为同期在我院行白内障手术并植入单焦点人 工晶状体(SN60AT,Alcon) 的患者共 26 例。 结果:12mo 复诊时,Tetraflex 组相较对照组拥有更好的裸 眼远视力和裸眼近视力,但两者相比差异无统计学差异。 两组的脱镜率分别为 34. 7% 和 26. 9% ,两者相比差异亦 无统计学差异(字 2 = 0. 355,P = 0. 551) 。 满意度调查显示 两者之间无明显差异(字 2 = 2. 367,P = 0. 124) 。 前、后囊膜 的混浊情况出现比率分别为 34. 8% 和 7. 7% (字 2 = 3. 972, P = 0. 046) ,Tetraflex 组明显高于对 照

At the 12-month follow-up visit, uncorrected distance visual acuity (UCDVA) and uncorrected near visual acuity (UCNVA) were measured to determine the efficacy of the IOL. Incidence of spectacle independence, patients蒺 satisfaction and presence of visual disturbances were investigated. In addition, anterior and posterior capsule opacification were assessed. Twenty-six patients (26 eyes) with implantation of monofocal IOLs (SN60AT, Alcon) were recruited as control group. 誗RESULTS:At the 12-month follow-up visit, the patients in Tetraflex accommodative IOLs group had better UCDVA and UCNVA than those in control group, but no significant difference was found (P > 0. 05). There were 34郾 7% patients of Tetraflex accommodative IOLs group and 26. 9% patients of control group achieving total spectacle independence, and no significant difference was found (字 2 = 0. 355, P = 0. 551). Patients蒺 satisfaction rates with two groups did not differ significantly too (字 2 = 2. 367, P = 0. 124). Anterior and posterior capsule opacification were present, respectively, in 34. 8% and 7. 7% of patients (字 2 = 3. 972, P = 0. 046). Two cases of accommodative IOLs displacement were discovered (字 2 = 0. 659, P = 0. 417). No visual disturbances were mentioned in both groups. 誗 CONCLUSION: In the long run, compared with monofocal IOLs, Tetraflex accommodative IOLs can not provide efficient uncorrected visual acuity and had higher incidence and degree of anterior and posterior capsule opacification. Patients implanted have lower satisfaction rate due to poor accommodative ability versus expensive material. So, accommodative IOL should be implanted prudently, especially to the patients with high risk factors for capsule fibrosis. 誗
