摘要
目的评价激光治疗性角膜切削术对翼状胬肉单纯切除术后部分有复发趋势患者使用的效果。方法将50例原发性翼状胬肉术后2周术区结膜或角膜缘出现新生血管的患者随机分为两组,观察组予准分子激光彻底清除角巩膜缘周边再生长新生血管（激光参数拟设定：能量密度195 m J/cm2;光斑直径为0.95 mm,每脉冲切削深度0.2μm/pulse;光区4 mm）,切削范围超过创面约1 mm,每次间隔1周,共1-3次。对照组不行激光治疗。结果观察组与对照组复发率比较,差异有统计学意义（P〈0.05）。结论激光治疗性角膜切削可封闭翼状胬肉术后2周出现的新生血管,能明显降低翼状胬肉术后复发率,操作简单,患者痛苦少,可作为防止翼状胬肉术后复发的一种有效方法。
Objective To evaluate the effect of phototherapentic keratectomy （FTK） on simple excision of pterygi- tun in patients with the trend of recurrence. Methods Totally 50 cases of postoperative pterygium patients who developed conjunctival and/or corneal neovascularizatien were randomly divided into two groups. In the observation group, excimer la- ser was used to remove the neovasculadzation on limhus area. The laser parameters were set as： energy density 195mJ/ cm2, spot diameter 0. 95mm, cutting depth 0.2 μm/pulse, light region 4 mm. Cutting range were over 1 mm in all pa- tients. Treatment interval was 1 week, and continued for 3 weeks. Results There was significant difference in the recur- rent rote between the two groups （ P 〈 0.05 ）. Conclusion Use excimor laser to remove neovascularisatien that usually occurred at 2 weeks after the primary surgery in pteryginm patients can reduce the recurrent rate of pteryginm and relieve patient＇s pain. It is an effective method to prevent the recurrent pterygium.
