To evaluate the clinical results in patients with myopia up to -6 dioptres (D) after refraction surgery, evaluate their stability and compare photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK).
The authors evaluated before and after surgery the refraction values in patients with myopia up to -6 D operated in 1999 and 2000. The patients were subjected to standard examination before operation, one week, 1, 3, 6 and 12 months after operation. The group comprised a total of 542 eyes, 452 PRK eyes and 90 LASIK eyes.
After PRK surgery the mean spherical refraction after one year was -0.35 +/- 0.71 D, the mean astigmatism -0.63 +/- 0.38 D, UCVA 0.90 +/- 0.19, BCVA 0.98 +/- 0.11. After LASIK surgery after one year the mean spherical refraction was -0.10 +/- 0.81. D, the mean astigmatism -1.05 +/- 0.65 D, UCVA 0.80 +/- 0.24, BCVA 0.86 +/- 0.21.
Both methods proved effective and safe for correction of myopia up to -6 D. The results at our clinic are comparable with other departments and are stable in different years. PRK and LASIK achieve equal postoperative results after an interval of 3 to 6 months following surgery.
评估屈光手术治疗近视度数达-6屈光度（D）患者的临床效果，评估其稳定性，并比较准分子激光角膜切削术（PRK）和准分子原位角膜磨镶术（LASIK）。
作者评估了1999年和2000年接受手术的近视度数达-6 D患者手术前后的屈光值。患者在手术前、术后1周、1、3、6和12个月接受标准检查。该组共有542只眼，其中452只眼行PRK手术，90只眼行LASIK手术。
PRK手术后一年，平均球镜屈光为-0.35±0.71 D，平均散光为-0.63±0.38 D，裸眼视力（UCVA）为0.90±0.19，最佳矫正视力（BCVA）为0.98±0.11。LASIK手术后一年，平均球镜屈光为-0.10±0.81 D，平均散光为-1.05±0.65 D，UCVA为0.80±0.24，BCVA为0.86±0.21。
两种方法治疗近视度数达-6 D均证明有效且安全。我们诊所的结果与其他科室相当，且在不同年份稳定。PRK和LASIK在术后3至6个月后可获得相同的术后效果。
