目的探讨玻璃体切割术后白内障的超声乳化吸除术手术治疗的临床效果。方法将289例(352眼)玻璃体切割术后白内障患者半随机分为眼内灌注组和无灌注组。并对其原发眼底病类型、手术并发症、术后视力、白内障类型进行相关分析。结果眼底病类型、手术并发症、术后视力、白内障类型各因素中,,低眼压与脉络膜上腔出血与术式选择相关。本组研究中发生脉络膜上腔出血眼均为多次玻璃体视网膜手术后眼(P=0.017),且行白内障手术未做后节眼内灌注。术后低眼压在无灌注组更为多见(P=0.021)。对于其他并发症及术后视力恢复,两组病例并无统计学意义。结论超声乳化吸除术治疗玻璃体切割术后白内障减少了术中低眼压的危险性。对于核性白内障尤其是硬核白内障,放置后节眼内灌注是安全而有效的。
Objective To investigate the clinical effect of phacoemulsification surgery for vitreous cataract after vitrectomy. Methods 289 cases (352 eyes) of post-vitrectomy cataract patients were randomly divided into intraocular perfusion group and no perfusion group. And its primary fundus disease type, surgical complications, postoperative visual acuity, cataract types were analyzed. Results The types of ocular fundus, surgical complications, postoperative visual acuity and cataract type were all related to hypotony and choroidal hemorrhage. In our study, all patients underwent vitreoretinal surgery after multiple vitreoretinal surgery (P = 0.017). Intraocular perfusion was not performed after cataract surgery. Postoperative IOP was more common in the non-perfusion group (P = 0.021). For other complications and postoperative visual acuity recovery, two groups of patients did not reach statistical significance. Conclusion Phacoemulsification for the treatment of cataract after vitrectomy reduces the risk of intraoperative low intraocular pressure. Intraocular intra-ocular perfusion is safe and effective for nuclear cataracts, especially hard cataract.
