目的　探讨硬核 (Ⅲ级以上 )白内障采用小切口非超声乳化摘出加人工晶体植入的应用方法及疗效。方法对 74例 77眼硬核白内障施行 5 .5～ 6mm巩膜隧道小切口非超乳囊外摘出 ,象限咬切法娩核 ,Ⅰ期植入后房型人工晶体 74眼 ,术后定期观察角膜、前房炎症反应、散光等。结果　术后 3d、1个月、3个月矫正视力分别为≥ 1.0者6眼 (7.79% ) ,11眼 (14 .2 9% ) ,18眼 (2 3.38% ) ;≥ 0 .5者 32眼 (4 1.5 6 % ) ,5 6眼 (72 .73% ) ,6 0眼 (77.92 % )。术后无严重并发症 ,散光与超声乳化术相近。结论　对于硬核白内障采用小切口非超乳囊外摘出 ,疗效可靠 ,手术快捷 ,经济安全 ,对眼内组织损伤小 ,疗效与超声乳化接近 Objective To investigate the application of non-phacoemulsification and intraocular lens implantation in cataract patients with grade Ⅲ or higher cataracts. Methods Seventy - seven eyes of 77 patients with hard - core cataract were enucleated with a small incision of 5.5-6 mm scleral tunnel incision outside the non - supercapsular sac. The nucleus was resected by quadrant bite resection and 74 cases of posterior chamber intraocular lens (IOL) were implanted. The cornea, Anterior chamber inflammation, astigmatism and so on. Results The corrected visual acuity was ≥ 1.0 in 6 eyes (7.79%), 11 eyes (14.29%), 18 eyes (2.38%) at 3d, 1 month and 3 months respectively. Eyes (4 1.56%), 56 eyes (72.73%) and 60 eyes (77.92%). No serious postoperative complications, astigmatism and phacoemulsification similar. Conclusion For the hard cataract with a small incision outside the non-supercapsular extracapsular extraction, the curative effect is reliable, the operation is quick, the economy is safe, the damage to the intraocular tissue is small, and the curative effect is close to the phacoemulsification
