无缝线小切口白内障摘除人工晶体植入术临床分析

The Clinical Analysis of Cataract Extraction by the Micro-incision Operation and Artificial Lens Implantation

目的探讨无缝线小切口白内障摘除人工晶体植入术的疗效.方法对120例(142眼)老年性白内障行无缝线小切口白内障摘除人工晶体植入术,并与同期116例(136眼)现代囊外摘除人工晶体植入术对比.结果小切口组术后1周、2周、1个月裸眼视力≥0.5的眼数分别为106眼(74.64%),117眼(82.38%),130眼(91.54%),明显高于对照组(P<0.05).小切口术前平均角膜散光为(0.88±0.41)D,术后1周为(1.55±0.58)D,术后2周为(1.33±0.45)D,术后1个月为(1.08±0.46)D,手术前后差异无显著性(P>0.05).对照组术后平均角膜散光高于小切口组且差异有显著性.结论无缝线小切口白内障摘除人工晶体植入术具有手术创伤小、术后视力恢复快、术后散光小的优点,适合基层医院及防盲工作中运用.

Objective To evaluate the therapeutic effect of micro -incision cataract extraction and artificial implantation. Methods The contrast was finished between 120 patients with the senile cataract extracted by the micro - incision operation plus artificial lens implantation and 116 same patients treated by the cataract extraction plus artificial lens implantation. Results The first week, the second week and the first month after the micro - incision operation, groups, the naked - eye vision is better or equals 0. 5 was as follows respectively： 106 （74. 64% ）, 117 （82.38%）, 130 （91.54%）. The statistic result of experimental groups was more significant than that of the controls （ P 〈0. 05 ）. The average corneal astigmatism of patients was, （0. 88 ±0. 41 ） D before the operation, 1.55 ± 0. 58, 1.33 ± 0. 45 and 1.08 ± 0.46 on the seventh day, the fourteenth day and the first month after the micro - incision operation. There was no significance in the pre and post operation （ P 〉 0.05）. The average corneal astigmatism in the experiment groups was more significant than that in the control groups. Conclusions Superiority of the micro - incision cataract operation plus artificial lens implantation was concluded as follows： little impairment, rapid vision - restore, insignificant astigmatism, being applied to the blindness prevention in the subordinate hospital.
