Iris Incarceration Following Difficult Cataract Surgery

A 65-year-old female presented for a routine visit to our clinic three weeks after surgery. Cataract surgery was slightly more difficult due to a shallow anterior chamber and narrow pupil. The patient was satisfied after surgery and claimed to be free of symptoms. During the slit-lamp examination, an iris incarceration was observed at the paracenteses at the 10 o’clock position.

A CASIA2 ­anterior ­segment OCT was performed for a more detailed assessment. The radial cross-­sectional images enabled a clear visualisation of the incarceration and the underlying structures. The imaging allowed precise planning of the anterior chamber revision on the following day. In the postoperative follow-up anterior segment OCT, a mild persistent iris defect was seen at the affected location, which was not perceived as bothersome by the patient.
