Opaque iris claw lens in a phakic eye to correct acquired diplopia

A 25-year-old man had diplopia caused by abducens nerve paresis on both sides after cranial injury. Because of the patient's reports of persistent diplopia after surgical correction, a specially manufactured, tinted iris claw lens was implanted in the left eye, with the crystalline lens in situ. Fourteen years after surgery, specular microscopy was performed to evaluate the corneal endothelium. The difference in mean endothelial cell density in both eyes was 18.6%. The difference between eyes in polygonality and polymegathism was not significant.
