[Spontaneous rupture of nylon sutures in the cornea spontaneously (author's transl)].

In 8 patients rupture of nylon sutures in the cornea occurred spontaneously. This happened four times after a corneal cataract extraction, three times after a perforating keratoplasty and once after a perforating corneal injury. The rupture appeared three times 6 1/2 to 7 months after the operation, once after 1 1/2 months. In the other 4 cases the time of rupture is not known. The examination of the nylon sutures with a microscope showed a lamellar-concentric reduction in the straight parts of the sutures and superficial and deep sagittal in the curved parts of the sutures.
