Spontaneous fistula formation as a complication of relaxing incisions with suture placement for postkeratoplasty high astigmatism.
A 39-year-old man had a corneal relaxing incision with corneal compression suture placement to correct more than 10 diopters of corneal astigmatism. A permanent fistula formed from the compression suture, resulting in a localized corneal pocket of aqueous that broke through the surface. The aqueous drained into the tear film, requiring major surgical repair.
