I had lasik surgery on both eyes in Dec. 2005. My right eye is 20/20. The left eye was 20/40. I wanted to improve the left eye so I would not have to wear glasses, or a contact. I underwent a PRK surgery in Dec. 2008. It left me with what the doctor calls a herpetic PRK post scarring. My left eye has scarred cornea now. I see a lot of black spots out of a foggy eye. My doctor is exploring a possible wavefront PRK. He has never done one. He is also exploring an epithelial laser scrape. I am concerned and afraid. Is there a safe way to remove the fog and scarring from my eye?
