小切口非超声乳化白内障摘除及人工晶状体植入术临床效果 　　【摘要】目的 探讨小切口非超声乳化白内障囊外摘除及人工晶状体植入术的临床效果。方法 术眼右上象限切口进前房后，连续环形撕囊待水分离核后，用晶状体圈匙摘出晶状体核，囊袋内植入人工晶状体，麻醉按白内障手术常规。术前充分散瞳，在手术显微镜下完成手术。结果 术后各期视力恢复情况：132例148眼手术后第1天、1周、1月后视力均有大幅度提高。其中术后1周，裸眼视力≥0.5(72.79％)，≥0.8(43.24％)。术后1月矫正视力≥0.5(81.75％)，≥1.0(51.35％)。结论 小切口非超声乳化白内障摘除术有切口愈合快、术后反应轻、减少术后散光，并发症少等优点。 　　【关键词】小切口非超声乳化 白内障囊外摘除术 人工晶状体 　　中图分类号：R776.1 文献标识码：A 文章编号：1005-0515（2012）3-043-02 　　Clinical efect of small incision non-phacoemulsification cataract extraction and Artificial lens implantation 　　ZHU Dayong1 ZHU Wenxuan2 TIAN Cuiling1 　　（1.Department of Ophthalmology，People’s Hospital of Pixian，Chengdu，Sichuan，611730；2．Second People’s Hospital of Pixian，Chengdu，Sichuan，611733） 　　【Abstract】Objective To investigate the clinical effect of the small incision non-phacoemulsification extracapsular cataract extraction and Artificial lens implantation．Methods An incision was made into anterior chamber in the right upper quadrant of the operative eye，and after continuous circular capsularhexis and hydrodissection，the lens nucleus was extracted by lens ring and finally the artificial lens was implanted in the bag．Anesthesiaaccording to conventional cataract surgery．Preoperative pupil dilation fully in operation under the operatingmicroscope．Results The postoperative visual recovery phases：post-operative 1 day，1 week and 1 month，148 eyes 132 cases vision has a substantial increase．1 week after which theuncorrected visual acuity of 0.5 accounted for 76.35％，51.35％ more than 0.8．1 month vision，84.24％ more than 0.5，58.10％ more than 1.0．Conclusion The smallincision non-phacoemulsificationcataract surgery has the advantage of faster wound healing，postoperative reactions，reduce postoperative astigmatism，and few complications． 　　【Keywords】small incision non-phacoemulsification extracapsular cataract extraction Artificial lens 　　 　　白内障是目前一种主要致盲眼病，白内障摘出及人工晶状体植人术是目前较为理想的复明手术。超声乳化技术自1967年Keiman首次报道后，因其切口小、术后散光小、视力恢复快等优点，已成为首选方法。但是此术式也有缺点，如学习曲线长、设备昂贵、手术价格高、受晶状体核硬度影响较大，难以
