We share the concern of Drs. Leccisotti and Fields that the casual reader might use the results of our article as a license to omit MMC when performing PRK. Severe corneal haze can be visually devastating and when our patients develop haze, it affects not only the quality of their vision, but also their ability to deploy with their military unit. Any patient with a high refractive error can develop haze after PRK, including patients with high myopia, high hyperopia, and high astigmatism. Our review of the literature showed an incidence of post-PRK haze as low as 10% and as high as 63% in high myopia with earlier excimer lasers.
