目的：评价准分子激光角膜切削术（ＰＲＫ）对远视和散光的治疗效果。方法：采用美国ＳＣＡＮ－ １９５型准分子激光系统对２６ 例（４６ 眼） 远视和散光进行治疗，Ⅰ组为＋ ２．００ ～＋ ５．００ＤＳ有２４ 眼，Ⅱ组为＋ ５．２５ ～＋９．００ＤＳ有２２ 眼（ 伴散光的有２５ 眼，为＋１．２５ＤＣ～＋３．００ＤＣ） 。并进行治疗后跟踪观察。结果：术后视力：本组患者术后１ 年裸眼视力≥０．５ 者３５ 眼占７６％ ；≥０．８ 者２９ 眼占６３％ ；≥１ ．０ 者１９ 眼占４１ ％ 。其中伴有散光者２５ 眼经激光切削后，裸眼视力≥０ ．５ 者１６ 眼占６４％ ；≥０．８ 者１０ 眼占４０％ ；≥１ ．０ 者６ 眼占２４％ 。结论：ＰＲＫ治疗轻、中度远视是安全有效并且可行。
Objective: To evaluate the effect of excimer laser keratectomy (PRK) on hyperopia and astigmatism. Methods: 26 cases (46 eyes) of hyperopia and astigmatism were treated by SCAN-195 excimer laser system in the United States. There were 24 eyes with + 2.00 ~ + 5.00DS in group Ⅰ and + 5.25 ~ + 9 in group Ⅱ There are 22 eyes with 0.00DS (25 with astigmatism, + 1.25DC ~ + 3.00DC). After treatment and follow-up observation. Results: Postoperative visual acuity: the naked eye visual acuity ≥0.5 in one year after operation in 35 patients accounted for 76%; in ≥0.8, 29 eyes accounted for63%; ≥1. 0 of 19 eyes accounted for 41%. Accompanied by 25 astigmatism after laser cutting, visual acuity ≥ 0. 5 of 16 eyes accounted for 64%; ≥ 0.8 of 10 eyes accounted for 40%; 0 6 eyes accounted for 24%. Conclusion: PRK is safe, effective and feasible for the treatment of mild to moderate hyperopia.
