86 myopes undergoing photorefractive keratectomy (PRK) with refraction from -0.25 D to -12.00 D were divided into 4 groups: A: up to -2.75 D, B: -3.00 D to -5.75 D, C: -6.00 D to -8.75 D and D: -9.00 D to -12.00 D. 20 emmetropes of the same median age were evaluated as a control group. The patients were examined 2 years after PRK. 2. Best corrected visual acuity (BCVA) increased in groups A, C, D and decreased in group B compared to values one year after PRK. Both changes were only nonsignificant. 3. Contrast sensitivity (CS) was equal to values one year after PRK in group A, the same was true for groups C and D with exception of lower values in the highest spatial frequency. In group B, CS decreased significantly compared to values one year after PRK. 4. In groups A, B a C number of patients without rest correction increased, regression was seen only in group B. 5. BCVA changed only nonsignificantly under glare of 41.1 cd/m2, 342.6 cd/m2 and 1360.4 cd/m2 in 97% of patients.

86名接受屈光性角膜切削术（PRK）、屈光度在-0.25 D至-12.00 D之间的近视患者被分为4组：A组：屈光度最高达-2.75 D；B组：-3.00 D至-5.75 D；C组：-6.00 D至-8.75 D；D组：-9.00 D至-12.00 D。选取20名年龄中位数相同的正视眼患者作为对照组。患者在PRK术后2年接受检查。2. 与PRK术后1年的值相比，A组、C组、D组的最佳矫正视力（BCVA）提高，B组降低。这两种变化均无统计学意义。3. A组的对比敏感度（CS）与PRK术后1年的值相等，C组和D组除最高空间频率处的值较低外情况相同。与PRK术后1年的值相比，B组的CS显著降低。4. A组、B组和C组中未进行屈光矫正的患者数量增加，仅在B组出现回退现象。5. 在97%的患者中，在41.1 cd/m²、342.6 cd/m²和1360.4 cd/m²的眩光条件下，BCVA仅出现无统计学意义的变化。
