目的探讨小瞳孔白内障的超声乳化及折叠式人工晶状体的手术技巧和临床效果。方法临床确诊的小瞳孔白内障患者46例54眼,经透明角膜隧道切口,采用钝性分离的方法扩大瞳孔,行环行撕囊、双手原位超声乳化及折叠式人工晶体囊袋内植入手术。结果术后随访5～12月,术后视力提高46眼占85.19%,视力≥0.5者34眼占62.96%,所有患者的瞳孔保持生理性圆形或是近圆形。手术并发症主要有角膜水肿、前房纤维素性渗出、后囊破裂。结论掌握合理的手术技巧,小瞳孔白内障的超声乳化术同样可以取得良好的手术效果。
Objective To investigate the surgical technique and clinical effect of phacoemulsification and foldable intraocular lens in small pupil cataract. Methods Forty-six eyes of 46 patients with small pupil cataract diagnosed clinically were treated with clear corneal tunnel incision. The pupil was enlarged by blunt dissection. The circumcision capsulorhexis was performed with both hands in situ phacoemulsification and foldable intraocular lens implantation. Results The patients were followed up for 5 ~ 12 months. The visual acuity improved 46 eyes (85.19%), visual acuity ≥ 0.5 eyes (62 eyes), 34 eyes (62.96%). The pupil of all patients remained physiologically circular or nearly circular. Complications of surgery are mainly corneal edema, anterior chamber cellulose exudate, posterior capsule rupture. Conclusion To master a reasonable surgical technique, phacoemulsification of small pupil cataract can also achieve good surgical results.
