Recurrent vitreous hemorrhage secondary to haptic-induced chafing.
METHODS
After cataract extraction and placement of a posterior chamber intraocular lens, a 70-year-old man had 5 vitreous hemorrhages over 3 years. Iris transillumination defects and apposition of the nasal haptic and ciliary body were found.


CONCLUSIONS
Iris chafing is a rare complication of cataract extraction. Vitreous hemorrhage presumably resulted from iris erosion caused by the IOL haptic.
