[摘要] 目的 分析不同浓度丝裂霉素C对LASEK术后疗效的影响。方法 回顾性分析2012年1月—2014年12月该院行LASEK术治疗的90例(患眼156只) 高度近视眼患者临床资料,按照术中丝裂霉素C不同浓度的使用分为两组,对照组采用0.2 mg/mL患者38例(患眼68只),研究组采用0.4 mg/mL患者52例(患眼88只),对比两组治疗情况。结果 研究组角膜上皮愈合时间短于对照组,裸眼视力低于对照组,且Haze发生率19.32%小于对照组39.71%,对比差异有统计学意义(P<0.05);两组不良事件发生率均未超过10.00%,对比差异无统计学意义(P>0.05)。结论 LASEK术中采用0.4 mg/mL丝裂霉素C疗效显著,且可降低角膜上皮混浊发生率。

[Abstract] Objective To analyze the effects of different concentrations of mitomycin C on postoperative curative effect of LASEK. Methods The clinical materials of 90 high myopia patients (156 eyes) treated with LASEK in our hospital from January 2012 to December 2014 were retrospectively analyzed and divided into two groups, the control group and the observation group according to the use of different concentrations of mitomycin C in operation. 38 patients(68 eyes) in the control group received 0.2mg/mL of mitomycin C, 52 patients (88 eyes) in the research group received 0.4mg/mL of mitomycin C. The treatment conditions of the two groups were compared. Results The corneal epithelium healing time in the research group was shorter than that in the control group, the naked eyesight in the research group was lower than that in the control group, the incidence rate of Haze was lower than that in the control group (19.32% vs 39.71%), all the differences were statistically significant(P<0.05). The incidence rates of adverse events of the two groups were not more than 10.00%, and the comparison was not statistically significant(P>0.05). Conclusion It has an obvious curative effect using 0.4mg/mL of mitomycin C in LASEK, which can decrease the turbidity incidence rate of corneal epithelial.

角膜上皮混浊(Haze)是准分子激光上皮下角膜磨镶(LASEK)术后影响患者视力恢复的主要并发症,降低术后疗效[1]。大量临床研究表明:LASEK术中采用丝裂霉素C(MMC)能够有效阻碍Haze形成,但若使用不当可导致角膜毒性作用是不容忽视的,故不同浓度丝裂霉素C对LASEK术后疗效的影响仍值得深入研究[2-3]。为分析不同浓度丝裂霉素C对LASEK术后疗效的影响。该研究回顾性分析2012年1月—2014年12月该院行LASEK术中采用不同浓度Haze的90例高度近视眼患者临床资料,现报道如下。
1 资料与方法
1.1 一般资料
回顾性分析该院诊治的90例(患眼156只)高度近视眼患者临床资料,均接受LASEK术治疗。按照术中使用不同浓度MMC分为对照组(0.2 mg/mL,38例,患眼68只)和研究组(0.4 mg/mL,52例,患眼88只)。
对照组男20例,女18例,年龄18~40岁,平均(23.15±1.95)岁,等效球镜度-6~-11D平均(8.56±2.74)D;研究组男30例,女22例,年龄18~38岁,平均(22.75±1.25)岁,等效球镜度-6~-12 D平均(7.31±2.44)D。
1.2 方法
两组患者均在表面麻醉下根据术前最佳……
