Objective: to investigate the clinical effect of recombinant human epidermal growth factor eye drops combined with sodium hyaluronate in the treatment of dry eye after cataract surgery
【 abstract 】 : objective to observe and analyze the clinical efficacy of sodium hyaluronate eye drops combined with recombinant human epidermal growth factor (rhEGF) eye drops in the treatment of dry eye after cataract surgery.Methods a total of 84 patients with dry eye after cataract surgery admitted to our hospital from March 2018 to September 2019 were selected as the study subjects and randomly divided into two groups: the combined group and the control group, with 42 cases in each group.The control group was treated with sodium hyaluronate eye drops, and the combined group was treated with rhEGF eye drops on the basis of the control group.The dry eye symptom scores before and after 2 weeks and 4 weeks were compared between the two groups to evaluate the clinical efficacy of the two groups.Results the total effective rate of the combined group was 97.62%, significantly higher than that of the control group (80.95%), and the difference was statistically significant (P<0.05).Compared with before treatment, the clinical symptom scores of the two groups at 2 and 4 weeks after treatment were significantly reduced, and the difference was statistically significant (P<0.05).Compared with the control group at the same time point, the clinical symptom scores of the combined group at 2 and 4 weeks after treatment were significantly reduced, with statistically significant differences (P<0.05).Conclusion sodium hyaluronate eye drops combined with rhEGF eye drops can significantly improve the clinical symptoms of patients with xerophthalmia after cataract surgery and obtain satisfactory clinical efficacy.

白内障术后干眼症是临床上常见的一种眼表炎症性疾病,可引起泪液质和量异常及动力学异常,临床主要表现为眼部异物感,且常伴有眼部疲劳及视物模糊,轻度可影响日常生活和工作,严重者可危害
视功能,甚至导致失明[1]。本文观察分析了玻璃酸钠滴眼液联合重组人表皮生长因子(rhEGF)滴眼液治疗白内障术后干眼症的临床疗效,现报告如下。
1 资料与方法
1.1一般资料 选择我院2018年3月-2019年9月收治的84例白内障术后干眼症患者为研究对象,随机分为两组:联合组和对照组,每组42例。其中,联合组男性患者24例,女性患者18例,年龄59-81岁,平均年龄(67.58±6.54)岁。对照组男性患者25例,女性患者17例,年龄57-83岁,平均年龄(67.64±6.63)岁。两组患者的基本资料之间比较,差异均无统计学意义(P>0.05)。
1.2治疗方法 两组患者均于治疗前1周停止使用其他干眼症药物,对照组给予玻璃酸钠滴眼液滴眼,每次1滴,每日3次。联合组在对照组基础上加用重组人表皮生长因子滴眼液滴眼,每次1滴,每日3次。两组患者均治疗4周。
1.3观察指标 (1)比较两组的临床疗效。痊愈为临床症状完全消失,裂隙灯检查完全正常;显效为临床症状基本消失,裂隙灯检查情况好转;有效为临床症状基改善,裂隙灯检查情况改善;无效为临床症状、裂隙灯检查均无改善。(2)记录并比较两组患者用药前及用药2周、4周的干眼症状评分,详细询问患者眼部有无干涩感、异物感、烧灼感。采用0~3分制评价,0分为无症状,1分为偶尔出现症状,2分为间断出现轻度症状,3分为持续出现明显症状。
1.4统计学处理 采用SPSS17.0软件对数据进行统计分析,计数资料率的比较采用x2检验,计量资料组间比较采用t检验,当P<0.05时,为差异有统计学意义。
2 结果
2.1两组临床疗效比较 如表1所示,联合组总有效率为97.62%,明显高于对照组的80.95%,差异有统计学意义(P<0.05)。

2.2两组治疗前后症状评分比较 如表2所示,与治疗前比较,两组治疗后2周、4周的临床症状评分均明显降低,差异有统计学意义(P<0.05)。与对照组相同时间点比较,联合组治疗后2周、4周的临床症状评分均明显降低,差异有统计学意义(P<0.05)。

3 讨论
白内障是全球第一大致盲性眼病,随着社会老龄化的加剧及近视发病率的增加,其患病率也显著增加,手术是治疗白内障的主要方式。白内障术后干眼症的发病率较高,其原因与表面麻醉剂引起角膜上皮点状剥脱和泪膜稳定性下降、术中眼表上皮的机械性损伤、术后炎症反应及术后早期频繁使用含有防腐剂的滴眼液等有关[2]。白内障术后干眼症病程较长,且易反复发作,患者往往出现干涩感、异物感、烧灼感等症状,给患者日常生活、工作带来极大的不便,严重者甚至可以导致失明。玻璃酸钠滴眼液又名透明质酸钠,是由 N-乙酰葡萄糖醛酸反复交替而形成的高分子多糖体生物材料,其具有良好的生物相容性,在增加药物黏度的同时,还克服了眼睑不易眨动的缺点,使其成为滴眼液的良好载体,且在使用含有玻璃酸钠滴眼液时,眼表存在的玻璃酸钠滴眼液会形成一层膜覆盖在角膜上皮表面,因此其可长期存留在眼表,从而有利于药物长期有效的吸收,同时还有利于促进角膜细胞的再生;玻璃酸钠液滴眼液与泪液相似,具有与生物泪液相同的黏滞性和伸缩性,还有很好的生物耐受性,可以明显延长泪膜破裂时间,对泪膜起稳定作用[3]。本次研究结果显示,联合组总有效率为97.62%,明显高于对照组的80.95%;与对照组相同时间点比较,联合组治疗后2周、4周的临床症状评分均明显降低。综上所述,玻璃酸钠滴眼液联合 rhEGF 滴眼液可以显著改善白内障术后干眼症患者的临床症状,取得满意的临床疗效,值得临床推广应用。
