Traumatic aniridia through opposite clear corneal incision in a pseudophakic eye

Abstract

A 56-year-old man complaining of decreased visual acuity in his left eye visited the emergency room 1 hour after blunt trauma. Slit lamp examination showed no visible iris tissue. The corneal wound at 5 o'clock was sharp, and Seidel was negative. In the right eye, there was a main clear corneal incision (CCI) at 11 o'clock and an opposite CCI (OCCI) to correct corneal astigmatism at 5 o'clock in the left eye. Anterior chamber inflammation and hyphema resolved 4 weeks after the trauma. The intraocular lens and capsular bag were intact, and the corrected distance visual acuity returned to 20/25. To our knowledge, this is the first report of traumatic iris expulsion through a 3.0 mm OCCI. An OCCI may seal better than a main CCI, which is used in cataract surgery, because the OCCI is not used during the cataract procedure. However, surgeons should be aware of the risk for postoperative wound dehiscence associated with the OCCI.
