【摘要】 目的评价通过透明角膜切口的白内障超声乳化摘除及折叠式人工晶体植入手术的疗效。方法采用上方３．２ｍｍ梯形透明角膜切口，对９０例（１００只眼）老年性、并发性、先天性和外伤性白内障行超声乳化摘除，并植入硅胶或ＨＥＭＡ折叠式人工晶体。结果术后１天裸眼或球镜矫正视力≥０．５者占９３．０％；术后１周，１个月和３个月视力≥１．０者分别占５６．０％，６５．１％和６７．５％。术后１周平均散光为０．９３±０．５８Ｄ，比术前增加０．２０Ｄ（Ｐ＜０．００１）。术后１个月和３个月平均散光分别为０．７８±０．６０Ｄ和０．７３±０．５９Ｄ，与术前无统计学差异（Ｐ＞０．０５）。结论提示透明角膜切口的超声乳化和折叠式人工晶体植入术具有早期恢复和稳定眼屈光状态和视力的优点。更多还原

【Abstract】 Objective To evaluate the therapeutic effects of phacoemulsification with foldable intraocular lens implantation through a clear corneal incision. Methods The surgery was performed through a 3.2 mm clear corneal incision on 100 eyes of 90 patients with senile, complicated, congenital and traumatic cataracts. Results Postoperatively, the visual acuities with spherical correction or without correction were 0.5 or better in 93.0% of eyes at one day, and 1.0 or better in 56.0%, 65.1% and 67.5% at one week, one month and three months respectively. The mean postoperative astigmatism was 0.93±0.58 D at one week and 0.20D more than the mean preoperative one ( P <0.001). There was no statistical difference between the mean preoperative astigmatism and postoperative astigmatism at one and three months which were respectively 0.78±0.60 D and 0.73±0.59 D. Conclusion The phacoemulsification with foldable intraocular lens implantation through a clear corneal incision can reduce early postoperative astigmatism, shorten the period of visual rehabilitation and simplify operative procedures.更多还原
