目的:探讨视网膜色素变性并发白内障患者行超声乳化联合人工晶状体植入术的疗效。方法:视网膜色素变性并发白内障患者21例34眼行超声乳化联合人工晶状体植入术,观察手术前后视力、视野、视网膜电图及术后并发症等。结果:术前最佳矫正视力<0.3为31眼(91.2%),术后为19眼(55.9%),差异有统计学意义(χ2=9.14,P<0.01)。术后3 d最佳矫正视力:10眼≤0.1,9眼0.12-0.25,10眼0.3-0.5,5眼≥0.6。31眼(91.2%)视力较术前提高,3眼(8.8%)无变化。视野6眼(17.6%)与术前对照有所改善,视网膜电图无明显改变。术后角膜内皮水肿3眼(8.8%),黄斑水肿1眼(2.9%)。随访6个月时后囊膜混浊8眼(23.5%),其中较严重5眼(14.7%)行Nd∶YAG激光后囊切开术。结论:超声乳化联合人工晶状体植入术可有效提高多数视网膜色素变性并发白内障患者的中心视力,改善其生活质量。
Objective: To investigate the effect of phacoemulsification combined with intraocular lens implantation in patients with retinitis pigmentosa and cataract. Methods: Twenty-one eyes (34 eyes) with retinitis pigmentosa and cataracts underwent phacoemulsification combined with intraocular lens implantation. Visual acuity, visual field, electroretinogram and postoperative complications were observed before and after operation. Results: The preoperative best corrected visual acuity was 0.3 in 31 eyes (91.2%) and 19 eyes (55.9%) after operation. The difference was statistically significant (χ2 = 9.14, P <0.01). The best corrected visual acuity was at 3 days after operation: 10 eyes ≤0.1 eyes 9 eyes 0.12-0.25 eyes 10 eyes 0.3-0.5 eyes 0.5 eyes 0.6 eyes eyes (91.2%) visual acuity was improved compared with preoperative, 3 eyes (8.8%) Variety. 6 eyes (17.6%) had improvement compared with preoperative control, and electroretinogram had no significant change. Postoperative corneal endothelial edema in 3 eyes (8.8%), macular edema in 1 eye (2.9%). Eight eyes (23.5%) had posterior capsular opacities at 6 months after follow-up. The more severe 5 eyes (14.7%) underwent Nd: YAG laser posterior capsulotomy. Conclusion: Phacoemulsification combined with intraocular lens implantation can effectively improve the central vision of most patients with retinitis pigmentosa complicated cataract and improve their quality of life.
