方法：采用独创的钩核出核技术对25例30眼白内障患者进行手术，术中患者均采取半卧位。对患者术中后囊破裂、术后角膜水肿及视力情况进行统计。

结果：患者25例30眼中，术中无后囊破裂和悬韧带离断、玻璃体脱出，都顺利植入后房型人工晶状体，患者术后视力均有不同程度的提高。术后一过性角膜水肿1例，术后1wk内消退，术后2mo视力≥0.5者占85%。

结论：钩核出核技术独创性强，方法安全可靠，除普通病例外也适用于疑难复杂病例和情况，值得推广和应用。

METHODS: The clinical data of 25 patients(30 eyes)who were under semireclining position in manual small incision cataract surgery(ECCE)in which the two-hook extraction technique was used, the related complications such as capsule rupture, corneal edema and visual acuity were statistically analyzed.

RESULTS: No eyes experienced posterior capsule rupture, suspensory ligament transaction, vitreous prolapse during surgeries in 25 patients(30 eyes). Posterior chamber intraocular lens were implanted successfully, the visual acuity was improved with different extent. Transient corneal edema was noted in 1 eye and disappeared at 1wk postoperatively. Eighty-five percent have the visual acuity(≥0.5)at 2mo postoperatively.

CONCLUSION: The two-hook technique for nucleus extraction is safe and reliable, of high originality and can be applied in a wider range of indications other than normal cases. The technique is worthy of application in basic medical institutions.
