Se demuestra en la revista CÓRNEA algo que hemos constatado clínicamente en muchas ocasiones y es que la PRK en miopía media y baja tiene un riesgo bajo de haze, mientras que en miopías y astigmatismos altos, pero sobre todo en hipermetropías altas se multiplica por diez el riesgo de haze. Os ponemos un enlace al abstract y a un resumen en ingles.
RESÚMEN
A higher risk of haze is associated with hyperopic and large myopic or astigmatic corrections, but longer MMC application may help prevent haze, according to Igor Kaiserman, MD, MSc, MHA, and coresearchers. Their retrospective study of PRK with MMC included 7535 eyes; patients with a history of corneal pathology or surgery were excluded. Haze incidence, onset time, and corneal haze severity were the main outcome measures. The incidence of haze was 2.1% in eyes with high myopia compared with 1.1% in eyes with low to moderate myopia and 3.5 times higher in eyes with high astigmatism compared with low astigmatism. The overall incidence of haze was higher in eyes treated for hyperopia (10.8%) compared with myopia (1.3%). The study is published in the journal Cornea.
