Haze after Corneal Cross-Linking (CXL) is different in clinical character from haze after other procedures, such as PRK.
CXL associated haze is a dust-like change in the corneal stroma or a midstromal demarcation line, whereas haze due to other procedures (like PRK, LASEK etc...) has a more reticulated subepithelial appearance. Similarly, the mechanisms leading to haze formation may be different.
When I spoke to my doctor about the different types of haze he said they are very different. One is a "good" haze that will disappear with time (associated with CXL), whereas the "nasty" haze, caused by PRK/LASEK can be permanent and very difficult to get rid off.
As strange as this sounds, I am really happy that I have the "good" haze! It just means I have to be patient for around one year or so to have a clear haze-free cornea!
