| 摘 要： | 目的：探讨折叠式人工晶状体悬吊术后角膜散光的变化。方法：对20例21眼晶状体切除联合玻璃体切割术后无囊膜支撑或囊膜不足以支撑人工晶状体的无晶状体眼患者行折叠晶状体悬吊术,在术前、术后1wk;1,3mo行自动角膜曲率计检查,记录角膜平均屈光力及散光度,用矢量分析法计算手术性散光（SIA）度数,比较角膜散光的变化。结果：患者术后1wk;1,3mo均与术前角膜的平均屈光度比较差异无显著性（P〉0.05）;患者角膜散光度术后1wk与术前比较差异有显著性（P〈0.05）;术后1,3mo与术前比较差异无显著性（P〉0.05）;手术性角膜散光度术后1,3mo与术后1wk比较差异有显著性（P〈0.05）,术后3mo与1mo比较差异无显著性（P〉0.05）;角膜散光轴位有向逆规性散光方向转变的趋势。结论：无晶状体眼折叠型人工晶状体悬吊术后角膜平均屈光度变化小、术后3mo内基本恢复至术前状态,散光度及轴向术后1mo内变化明显,术后3mo内基本趋于稳定。

| Abstract: | AIM: To evaluate the changes of astigmatism induced by suture-fixation of foldable intraocular lens for aphakia correction. METHODS: Non-posterior capsular or disintegrated-posterior capsular eye were included in this study. Suture-fixation of foldable intraocular lens was performed on 20 cases (21 eyes). Keratometry measurements were obtained preoperatively, at postoperative 1 week, 1 month, 3 months respectively.The mean surgically induced astigmatism (SIA) and mean postoperative uncorrected visual acuity. Were recorded.SIAs were analyzed by "vector method". The changes of astigmatism were compared. RESULTS: The corneal refractive power between pre-operation and 1 week, 1 month, 3 months after surgery did not significantly change(P>0.05); the astigmatic power significantly changed(P<0.05) between pre-operation and 1 week after surgery, and did not significantly change (P>0.05) at 1 month and 3 months after surgery; the mean surgically induced astigmatism (SIA) power significantly changed(P<0.05) between 1 week and 1 month, 3 months after surgery, and did not significantly change (P>0.05) between 1 month and 3 months after surgery; astigmatic axis of large number of patients were ATR(against the rule) . CONCLUSION: The suture-fixation of foldable intraocular lens for aphakia correction affects corneal mean refractive power of optical zone minimally.The astigmatic power and axis are changed significantly at 1 month post-operation, and at 3 months are relatively stable. |
