剪开法前囊截囊术在晶状体半脱位白内障手术中的应用

目的探讨剪开法前囊截囊术在晶状体半脱位白内障囊外摘出术中应用的临床效果。方法晶状体半脱位白内障23例（23眼）。进行手法小切口白内障囊外摘出联合人工晶状体囊袋内植入术。术中采用剪开法进行前囊截囊。术后随诊6～24个月，平均10．5个月。结果手术中均未出现晶状体脱离范同扩大或玻璃体脱出增加，术后最佳矫正视力≥1．0者2眼（8．70％），≥0．5者7眼（30．43％），〈0．5者16眼中：2眼为视网膜色素变性、7眼为眼挫伤伴有不同程度的视网膜挫伤、2眼为外伤性视神经萎缩、2眼为玻璃体浑浊（陈旧血性）、1眼为外伤性黄斑孔、2眼为≥-10．00D高度近视。结论应用剪开法前囊截囊术进行晶状体半脱位手法小切口白内障囊外摘出人工晶状体植入术是安全的．效果良好。

The application of anterior capsulectomy by scission in cataract surgery for lens subluxation

Objective To study the clinical efficacy of the application of anterior capsulectomy by scission in extracapsular cataract extraction (ECCE) for patients with lens subluxation. Methods 23 cases (23 eyes) with lens subluxation and cataract were treated by small incision ECCE combined with intraocular lens( IOL) implantation surgery. The scission was applied in anterior capsulectomy during operation. The cases were followed up for 6～24 months, 10.5 months in average. Results There were no expansion of lens detachment or increasement of vitreous prolapse during operation. The best corrected visual acuity (BCVA) of those cases were: 2 eyes ( 8. 70 % ) no less than 1.0,7 eyes ( 30. 43 % ) no less than 0. 5 and 16 eyes less than 0.5. Of those 16 eyes with BCVA worse than 0. 5,2 eyes were retinitis pigmentosa,7 eyes were ocular contusion combined with different degrees of retinal contusion, 2 eyes were traumatic optic nerve atrophy, 2 eyes were vitreous opaque ( obsolete hemorrhagic ) , 1 eye was traumatic macular hole and 2 eyes were high myopia( - 10.00 diopters or higher). Conclusion The application of anterior capsulectomy by scission is safe and satisfactory in small incision ECCE combined with IOL implantation surgery for lens subluxation.
