白内障超声乳化摘除及无缝线小切口折叠式人工晶体植入术

Phacoemulsirication and foldable intraocular lens implantation through a small sutureless incision

目的评价超声乳化白内障摘除及无缝线小切口折叠式人工晶体植入手术的疗效。方法对６５例（７２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，通过３．２ｍｍ切口植入硅胶折叠式人工晶体。结果术后１天裸眼或矫正视力≥０．５者占９４．４％；术后１周，１个月和３个月视力≥１．０者分别占７０．８％，７５．８％和７６．５％。术后１周和１个月平均散光分别为０．８９±０．８３Ｄ和０．７３±０．７６Ｄ，分别小于６．５ｍｍ切口对照组（Ｐ＜０．００１），但３个月时无统计学差异（Ｐ＞０．０５）。结论提示无缝线小切口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。

Objective To evaluate the therapeutic effects of phacoemulsification and the foldable intraocular lens implantation.Methods The surgery was performed through a 3 2 mm incision on 72 eyes of 65 patients with senile, complicated, congenital and traumatic cataracts.Results Post operatively, the visual acuities with spherical correction or without correction were 0 5 or better in 94 4% at one day, and 1 0 or better in 70 8%,75 8% and 76 5% at one week, one month and three months respectively. The mean post operative astgmatism was 0 89±0 83 D at one week and 0 73±0 76 D at one month which was respectively less than that in the control group with a 6 5 mm incision ( P <0 001),but no statistical difference between them at three months ( P >0 05).Conclusion The foldable intraocular lens implantation through a small sutureless incision could reduce early post operative astigmatism and shorten the period of visual rehabilitation.
