目的 探讨小切口非超声乳化白内障摘出及人工晶体植入术的方法及效果。方法 在上方角巩缘後做5.5mm角巩膜隧道小切口,对67例(81只眼)老年性白内障行晶体分 割术摘出,并植入人工晶体。对照组采用现代白内障囊外摘出(ECCE)及人工晶体植入术进行前瞻性研究。结果 术後3天裸眼或球镜矫正视力≥0.5者小切口组占91.36％,对照组占63.16％,两组之间判别具有非常显著性(X~2检验,P<0.01),小切口组术後3天、1周、1月和3月时的裸眼或球镜矫正视力的平均值均高于对照组(t检验,P<0.05)。结论 小切口白内障摘出及人工晶体植入术可获得与超声乳化术相近的术後结果,但对Ⅳ级以上硬核白内障则更安全,且投资小,有一定的临床应用价值。
Objective To investigate the method and effect of small incision non-phacoemulsification cataract extraction and intraocular lens implantation. Methods A small incision of 5.5 mm angle scleral tunnel was performed after the upper corner margin, and 67 cases (81 eyes) of senile cataract were subjected to segmentectomy and implanted intraocular lens. The control group was prospectively studied using modern extracapsular cataract extraction (ECCE) and intraocular lens implantation. Results Three days after operation, the visual acuity of naked eye or spherical was ≥0.5, accounting for 91.36% in the small incision group and 63.16% in the control group. There was significant difference between the two groups (X ~ 2 test, P <0.01) The mean values of uncorrected or spherical corrected visual acuity at 3 days, 1 week, 1 month and 3 months after operation were significantly higher than those in the control group (t test, P <0.05). Conclusions Small incision cataract extraction and intraocular lens implantation can achieve similar results after phacoemulsification. However, it is more safe and less costly to invest in patients with grade Ⅳ and above cataract, and it has certain clinical value.
