Purpose:
To present a case of isolated total iris expulsion through a self-sealing cataract incision 2 weeks postoperatively due to vomiting.
Methods:
Ophthalmological examination included visual acuity assessment, tonometry, slit-lamp examination, fundus ophthalmoscopy and ultrasound examination.
Results:
A 65-year-old woman experienced sudden visual loss during an episode of vigorous vomiting 2 weeks after uncomplicated phacoemulsification cataract surgery with a sutureless corneal incision. Clinical examination showed a dense anterior chamber haemorrhage. When the blood had cleared, isolated total aniridia was seen.
Conclusions:
This is the first reported case of aniridia after cataract surgery due to vomiting.
