小切口劈核术在硬核性白内障手术中应用的临床分析

Clinical research about hard-nucleus cataract operation with neucleus chopping in small incision technique

目的探讨小切口劈核法白内障摘除术治疗硬核性白内障的临床效果。方法对164例(188眼)核硬度>Ⅲ级高龄白内障患者分别施行小切口劈核法白内障摘除术与超声乳化白内障摘除术,观察两种术式术后裸眼视力、角膜散光、角膜水肿的差异。结果两组患者术后视力、角膜散光差异无统计学意义(P>0.05),两种术式术后角膜水肿差异有统计学意义(P<0.05)。结论对核硬度>Ⅲ级高龄白内障患者,在基层医院选择小切口劈核法白内障摘除术较超声乳化白内障摘除术角膜水肿明显减少,术后效果好。

Objective To analyze clinic effect with neucleus chopping in small incision technique in hard-nucleus cataract operation. Methods To treat 164 cases（188 eyes）eld hardness〉 Ⅲ cataract with neucleus chopping in small incision technique and Phacoemulsification. Observe nude acuity of vision, cornea astigmatism, corneal edema of two operative methods. Results After operation acuity of vision,cornea astigmatism have none statistics difference （P〉0.05） in two groups, then corneal edema have statistics difference（ P〈0.05）. Conclusion About hardness〉Ⅲ cataract eld patients, to operate with neucleus chopping in small incision technique have more advantage in corneal edema than Phacoemulsification in basic level hospital.
