    Researchers retrospectively analyzed results from 269 eyes that underwent PRK with application of mitomycin C (MMC) 0.02% for 120 seconds (n = 74), 60 seconds (n = 36), or 12 seconds (n = 159, including 38 with high myopia) and found no statistically significant difference in corneal haze scores or postoperative BCVA among the three groups.  All eyes achieved at least 20/25 BCVA and all eyes had a haze grade of 0.0, except two eyes with a haze grade of 0.5. Mean follow-up ranged from 10 to 31 months.
