摘要
目的：探讨准分子激光屈光性 ９９ 角膜切削术（ Ｐ Ｒ Ｋ）治疗近视眼的临床疗效。方法：应用准分子激光角膜切削术，对 ６４０ 例近视眼患者进行治疗。术前屈光度为－ ２００ Ｄ～－ ８５０ Ｄ，分为两组，一组为轻、中度近视（－ ２００ Ｄ～－ ６００ Ｄ）；二组为高度近视（≥－ ６２５ Ｄ）。对两组术后１ 年视力及角膜上皮下雾样混浊（ Ｈａｚｅ）进行统计学分析。结果：轻、中度近视组术后１ 年的平均视力为１１６，高度近视组为０９４。 Ｈａｚｅ：轻、中近视组是 ０１２ 级，高度近视组为 ０４３ 级。结论： Ｐ Ｒ Ｋ 对于轻。
Objective:To explore the effects of PRK in myopia.Methods:640 myopia eyes were treated by PRK.The patients were divided into two groups:the low and moderate myopia (-2 00 D～-6 00 D),and the severe myopia(≥-6 25 D).The Haze of post operation (PRK) was statistically analyzed.Results:The average naked vision of 1 year after operation was 1 16 in low and moderate group,0 94 in severe group ( P <0 01).Otherwise,the Haze was 0 12 degree in low and moderate groups,and 0 43 degree in severe group.Conclusion:The clinical effects of PRK in low and moderate myopia are better than those in severe myopia.
