摘要
目的:在硬核白内障术中保留全部核块和残留部分核块时先行植入人工晶体作为垫板后再行白内障超声乳化摘除,比较两组疗效。方法:采用双盲随机前瞻性对照研究,选取2016年6月-2019年6月莆田市第一医院眼科行白内障超声乳化吸除联合人工晶体植入术的年龄相关性白内障患者80例(80只眼)。采用随机数字表法分为组1(残留部分核块)和组2(保留全部核块),各40例(40只眼)。观察术后视力、中央角膜厚度、角膜内皮丢失率、角膜内皮细胞数、术中并发症发生情况。结果:两组术前及术后视力、术前角膜内皮细胞数、术前及术后第7天中央角膜厚度比较差异均无统计学意义(P>0.05)。术后第7天,组2角膜内皮细胞丢失率高于组1(P<0.05);术后第1天,组2中央角膜厚度高于组1,差异均有统计学意义(P<0.05)。组2术中1例后囊膜破裂。结论:硬核白内障术中超声乳化联合人工晶体垫板技术,残留部分核块的疗效优于保留全部核块。
Objective:To compare the curative effect between patients whose intraocular lens-shell are first implanted with a whole and partial nucleus and then phacoemulsification is performed in dense nuclear cataracts surgery.Method:A double-blind randomized prospective controlled study was conducted to select 80 age-related cataract patients(80 eyes)who underwent phacoemulsification combined with intraocular lens implantation in the department of ophthalmology of Putian First Hospital from June 2016 to June 2019.By using random number table method,they were divided into the group 1(partial remnant nucleus)and the group 2(whole nucleus),with 40 cases(40 eyes)in each group.The postoperative visual,central corneal thickness,loss rate of corneal endothelium,corneal endothelial cells count,intraoperative complications were observed.Result:There were no significant differences in preoperative and postoperative visual,preoperative corneal endothelial cell count,preoperative and 7 d after surgery central corneal thickness between the two groups(P>0.05).The loss rate of corneal endothelium 7 d after surgery in the group 2 was higher than that in the group 1(P<0.05);the central corneal thickness 1 d after surgery in the group 2 was higher than that in the group 1,the differences were statistically significant(P<0.05).There was 1 case of intraoperative posterior capsule rupture in the group 2.Conclusion:In dense nuclear cataracts surgery,phacoemulsification combined with intraocular lens-shell technique,the partial nucleus was superior to the whole nucleus group in the curative effect.
