Abstract

Objective To observe the application of illuminator guided retroillumination assisted continuous circular capsulorhexis. Methods A prospective study. Thirty eyes of 30 cases with cataract with vitreous hemorrhage, with poor fundus red reflex, from Sep. 2016 to Aug. 2017 in this hospital, were enrolled. After the ophthalmic endoilluminator was inserted into the vitreous, the endoilluminator was irradiated forward from the posterior lens capsule, then continuous circular capsulorhexis was performed. Phacoemulsification and vitrectomy were carried out routinely. The followed-up time was 8-12 months. Results The continuous circular capsulorhexis and phacoemulsification were performed successfully in all 30 eyes without any posterior capsule rupture. Vitreous hemaorrhage was completely removed, and retinal diseases was properly treated. The visual acuity before operation was HM-0.04 in 27 eyes(90.00%) and 0.05 in 3 eyes(10.00%). Postoperative visual acuity of all patients were 0.05 or better. The difference of visual acuity was statistically significant between before and after operation (χ2=49.091, P=0.000). Conclusion The illuminator guided retroillumination assisted continuous circular capsulorhexis can effectively solve the difficulty of poor red light reflex for cataract patients with vitreous hemorrhage. Key words: Capsulorhexis, circular, continuous, retroillumination; Phacoemulsification, lens; Vitrectomy

逆光辅助连续环形撕囊术的临床观察

目的观察照明器引导下反照辅助连续环形撕囊术的应用。方法前瞻性研究。选取本院2016年9月至2017年8月收治的30例伴有玻璃体出血、眼底红色反射差的白内障患者30只眼。将眼球内照器置入玻璃体后，从晶状体后囊向前照射，进行连续的圆形撕囊术。常规行超声乳化术和玻璃体切除术。随访8 ~ 12个月。结果30只眼均行连续环形撕囊和超声乳化术，无后囊膜破裂。玻璃体出血完全清除，视网膜疾病得到妥善治疗。术前视力HM-0.04 27眼(90.00%)，0.05 3眼(10.00%)。术后视力均在0.05及以上。手术前后视力差异有统计学意义(χ2=49.091, P=0.000)。结论照明器引导下逆行照明辅助连续环形摘除术能有效解决玻璃体出血白内障患者红光反射差的困难。关键词:撕囊;圆形;连续;超声乳化,镜头;玻璃体切除术
