Subjective and objective findings after radial keratotomy

Monocular diplopia secondary to radial keratotomy was investigated in a 42-year-old ophthalmologist. Under certain conditions, the patient observed a ghost image, loss of contrast, and variability in the subjective refraction. The objective findings were scissoring of the retinoscopic reflex, a prominent iron line, and localized flattening of the cornea.
