Complete spontaneous crystalline lens dislocation into the anterior chamber with severe corneal endothelial cell loss

PURPOSE: To report an unusual case of a spontaneously dislocated crystalline lens into the anterior chamber that was successfully treated. METHODS: A generally healthy 49-year-old woman with no history of trauma presented with a spontaneously dislocated crystalline lens into the anterior chamber accompanied by corneal endothelial cell loss. The crystalline lens was extracted intracapsularly after gentle separation from the corneal endothelium by using a viscoelastic material. RESULTS: Visual acuity remained at 20/16 from 1 day postoperatively, with little endothelial cell loss compared with preoperatively. CONCLUSIONS: A spontaneously dislocated crystalline lens into the anterior chamber with severe corneal endothelial cell loss was treated successfully by intracapsular extraction.
