The patient, a 53-year-old white man, complained of a bilateral decrease in vision over 7 years. He described the visual loss as affecting his right eye more than his left eye. There were no other symptoms, known diseases, or known allergies. Nine years ago, the patient underwent a LASIK procedure bilaterally at another institution. At the time of surgery, the patient was informed that he had a “corneal disease” that would not affect the surgical procedure. The patient is not aware of any family history of eye disease.
