    摘 要:目的 观察角膜矫形对近视眼的治疗效果，以及各种参数与疗效的关系和治疗中出现的副作用. 方法 对角膜矫形治疗的247例464只眼进行了3～12mo随访观察.对不同屈光度用3种不同的角膜矫形镜作治疗，统计屈光不正患者的不同参数与疗效的关系及各种副作用出现的时段与频率. 结果 角膜矫形治疗后，视力≥4.8的431只眼(92.9%)，视力≥5.0的348只眼(75.0%).屈光度≥-5.0D、角膜曲率≥45.0D、眼轴长≥25mm的患者以及早期未提供E值的患者，疗效均较差(P<0.01);13～17岁年龄组疗效较佳(P<0.01).主要副作用是角膜上皮损伤(初戴57.8%)和出现重影(3wk内45.7%)，1例患者出现顽固的视疲劳. 结论 角膜矫形技术是一项安全有效的提高近视眼裸眼视力的方法，对少儿近视的治疗较好，但应注意角膜上皮损伤及重影等副作用.
