摘要
目的评估准分子激光原位角膜磨镶术(LASIK)术后早期应用盐酸卡替洛尔滴眼液对屈光状态及眼压的影响。设计前瞻性比较性病例系列。研究对象2009年11月-2011年9月北京同仁医院行LASIK手术的近视患者32例(32眼)。方法试验组15眼LASIK术后第1周开始使用2%盐酸卡替洛尔滴眼液每日2次,低中度近视患者持续1个月,高度近视患者持续1.5个月。对照组17眼术后不使用2%盐酸卡替洛尔滴眼液。术前、术后1、3、6个月进行显然验光、Oculyzer眼前节测量系统、眼压等检查。主要指标等效球镜度、角膜后表面高度、眼压。结果试验组术后1、3、6个月时等效球镜度分别为(-0.150±0.742)、(-0.170±0.595)和(-0.525±0.618)D;对照组分别为(-0.258±0.581)、(-0.290±0.657)和(-0.459±0.591)D(P均>0.05)。试验组术后1、3、6个月时角膜后表面高度分别为(7.47±2.326)、(6.60±3.158)和(5.86±2.610)μm;对照组分别为(6.59±3.355)、(7.35±3.622)和(7.33±2.992)μm(P均>0.05)。试验组术后1、3、6个月眼压分别为(7.80±0.941)、(8.07±1.534)、(8.70±1.337)mm Hg;对照组分别为(9.35±2.827)、(9.59±2.717)、(8.73±1.580)mm Hg。术后1个月时试验组和对照组眼压有统计学差异(P=0.045),余时间点均无统计学差异。结论 LASIK术后早期应用盐酸卡替洛尔滴眼液通过降低眼压可能对屈光状态具有稳定作用。
Objective To assess the effects on refraction and intraocular pressure by early carteolol eyedrops application on eyes after laser in situ keratomileusis (LASIK). Design Prospective comparative case series. Participants 32 eyes of 32 patients with myopia undergone LASIK at Beijing Tongren Hospital were included. Methods 2% carteolol hydrochloride eye drops (15 eyes) were administered topically twice a day from the second week after LASIK to the end of the first month for patients with low to moderate myopia and through the end of the 1.5 months for patients with high myopia. 2% carteolol hydrochloride in control group (17 eyes) wasn't administered. The changes of spherical equivalent correction (SE) , the posterior corneal surface different value (Diff) and intraocular pressure (IOP) were observed preoperatively and 1 month, 3 months and 6 months after LASIK, respectively. Main Outcome Measures SE, the posterior corneal surface different value and IOP. Results The average SE of treatment group was (-0.150±0.742) D, (-0.170±0.595) D and (-0.525±0.618) D respectively at 1 month, 3 months and 6 months postoperatively, while it was (-0.258±0.581) D, (-0.290±0.657) D, and (-0.459±0.591) D respectively in the control group (all P〉0.05). The posterior corneal surface Diff of treatment group was (7.47±2.326) μm, (6.60±3.158) μm, and (5.86±2.610) μm respectively at 1 month,3 months and 6 months postoperatively, while it was (6.59±3.355) μm, (7.35±3.622) μm, and (7.33±2.992) μm respectively in the control group (all P〉0.05). The IOP of treatment group was (7.80±0.941)mm Hg,(8.07±1.534) mm Hg and (8.70±1.337) mm Hg respectively at 1 month, 3 months and 6 months postoperatively, while it was (9.35±2.827) mm Hg, (9.59±2.717) mm Hg and (8.73±1.580) mm Hg, respectively in the control group. The difference between the two groups was only significant (P=0.045) at 1 month. Conclusions Carteolol is effective to reduce IOP in early stage after LASIK and helpful to enhance the stability of the corneal biomechanical and the refraction. (Ophthalmol CHN, 2013, 22: 49-52)
