目的 探讨葡萄膜炎并发白内障,青光眼滤过术后白内障,外伤后并发白内障等特殊类型白内障超声乳化及人工晶体植入术的可行性、手术技巧及术后并发症的预防,并评价其疗效。方法 对34眼特殊类型白内障施行手术,术后随访1～6月。观察视力,角膜内皮细胞计数,眼压等并发症。结果 术后1月30眼(88.23％)有不同视力提高,视力≥0.3者18眼占52.94％角膜内皮细胞密度,平均面积,最大细胞面积,术前术后均未发生显著性差异。六棱细胞比例和变异系数发生显著性差异。除2例角膜水肿外无其他严重并发症。结论 选择好适应症,做好必要的术前检查,熟练掌握白内障超声乳化技术,对特殊类型白内障患者能够做到最大限度的提高术后视力。
Objective To investigate the feasibility of phacoemulsification and intraocular lens implantation in patients with uveitis complicated with cataract, cataract after glaucoma filtration surgery, cataract with special traumatic cataract and the prevention of postoperative complications, and to evaluate its curative effect. Methods Thirty-four eyes with special type of cataract underwent surgery and were followed up for 1-6 months. Visual acuity, corneal endothelial cell count, intraocular pressure and other complications were observed. Results There were different visual acuity in 30 eyes (88.23%) after operation. There were 18 eyes (≥0.3) accounting for 52.94% of corneal endothelial cell density, average area, maximum cell area and no significant difference after operation. Six-sided cell ratio and coefficient of variation occurred significant differences. No other serious complications were found except for 2 cases of corneal edema. Conclusion Select the indications, do the necessary preoperative examination, master phacoemulsification cataract surgery, for patients with special types of cataracts can do to maximize postoperative visual acuity.
