摘 要:目的:比较皮质类固醇激素和非甾体激素对预防PRK术后角膜混浊的疗效。方法:双眼屈光相同的近视患者50人(100只眼)、分为2组,第一组屈光度为>3.0D,≤6.0D,32人(64只眼);第二组屈光度为>6.0D、≤12.0D,18人(36只眼)。PRK术后按美国FDA标准主观评定角膜混浊。所有患者右眼使用0.1%艾氟龙预防角膜混浊,左眼使用0.03%欧可芬预防角膜混浊。结果:第一组3个月双眼角膜混浊均消退,角膜透明。第二组6个月后0.1%艾氟龙治疗眼有4只眼残存角膜混浊,0.03%欧可芬治疗眼有8只眼残存角膜混浊。结论:低、中度近视PRK术后0.1%艾氟龙与0.03%欧可芬效果相同,且非甾体激素治疗眼无眼压升高,在低、中度近视可应用0.03%欧可芬预防角膜混浊。在高度近视眼0.1%艾氟龙优于0.03%欧可芬。

Abstract:Objective:To evaluate the effect of cortioosteroid and non-steroid hormone in preventing corneal haze after PRK.Methods:50 cases with the same myopic degree in both eyes were involved in this study.The subjects were divided into two groups:low degree (-3.00D~-6.00D) and high degree group (>6.00D).Haze was classified according to FDA standard.0.1% FML was applied to the right eyes of all subjects and 0.03% ocufen to the left eyes.Results:In low degree group,the corneal haze in both eyes decreased and cornea was transparent 3 months after operation.However,in high degree group,the corneal haze remained in 4 eyes treated with 0.1% FML and 8 eyes treated with 0.03% ocufen for more than 6 months after operation.Conclusion:In low degree myopic group,the effect of 0.1% FML and 0.03% ocufen was similar.This showed that 0.03% ocufen could be used as a substitute of 0.1% FML to prevent the formation of haze in low and medium myopia.Its advantage was that no IOP rose.In high myopic group,the effect of 0.1% FML was better than 0.03% ocufen.

PRK作为治疗近视的有效方法,得到广泛应用,但是术后产生的角膜混浊,仍是主要并发症之一。目前预防PRK术后角膜混浊主要是局部应用皮质类固醇激素,但类固醇的长期应用可引起眼压升高及其它并发症。为此我们观察局部应用非甾体激素0.03%欧可芬(氟比洛芬)预防角膜混浊的效果,现报告如下。
1 临床资料
2.1 50人(100只眼)双眼屈光度相同或相近的近视患者,年龄18~46岁,平均28.16岁。按屈光度分为2组。第一组,屈光度为>3.0D,≤6.0D,32人(64只眼);第二组,屈光度为>6.0D,≤12.0D,18人(36只眼)。使用NIDEK,EC-500准分子激光,手术均由熟练操作者一人完成。
2.2 术后角膜上皮下混浊(Haze),以美国FDA标准主观评定。第一组48只眼为1级,
16只眼为2级;第二组22只眼为2级,14只眼为3级。
2.3 治疗方法:所有患者,右眼为皮质激素治疗眼,左眼为非甾体激素治疗眼。术后头3日右眼涂四环素可的松眼膏,左眼涂红霉素眼膏。第4日开始,右眼滴0.1%艾氟龙,每日3次。左眼滴0.03%欧可芬,每日4次。2周后,右眼每日滴2次0.1%艾氟龙,左眼每日滴3次0.03%欧可芬。
2 结果
72小时内有95%眼角膜上皮完全愈合。皮质激素治疗眼有5只眼(5%)上皮完全愈合延迟至5~7天,其中第一组1只眼,第二组4只眼。
治疗1个月后,皮质激素治疗眼有9只眼眼压升高,达25~36mmHg,而加用0.5%噻吗心安。
第一组3个月后,双眼角膜混浊均消退,角膜透明。皮质激素治疗眼和非甾体激素治疗眼,在术后2周、1个月、2个月,角膜上皮下混浊减退的程度基本一致。第二组术后6个月,皮质激素治疗眼有4只眼残存角膜混浊,占22%。非甾体激素治疗眼有8只眼残存角膜混浊,占44%。
