目的：探讨小切口不缝合白内障摘出联合人工晶体植入术的方法及效果。方法：４０例双眼白内障摘出联合人工晶体植入术的患者一只眼行小切口，另一只眼做常规切口进行前瞻性研究。结果：小切口组术后第１日至第３个月的散光变化为０．７０Ｄ，常规切口组为４．６６Ｄ，两组之间有非常显著性差异（ｔ检验，Ｐ＜０．００１）。小切口组术后第１日、１周和１个月时的裸眼视力及第１周时矫正视力的平均值均高于对照组（ｔ检验，Ｐ＜０．０５）。结论：小切口白内障摘出联合人工晶体植入术可获得与超声乳化术同样的效果，但投资小，更适合在我国推广。
Objective: To investigate the method and effect of small incision cataract extraction combined with intraocular lens implantation. Methods: Forty patients with binocular cataract extraction and intraocular lens implantation were given one small incision in one eye, and the other was performed conventional incision for prospective study. Results: The changes of astigmatism on the 1st day to the 3rd month after operation in the mini-incision group were 0.70D and 4.66D in the conventional incision group. There was a significant difference between the two groups (t test, P <0.001) . The average visual acuity of uncorrected visual acuity and the corrected visual acuity of the first week, the first week and the first month after operation in the small incision group were significantly higher than those in the control group (t test, P <0.05). Conclusion: Small incision cataract extraction combined with intraocular lens implantation can obtain the same effect as phacoemulsification, but the investment is small, more suitable for promotion in our country.
