Traumatic fracture of flexible anterior chamber intraocular lenses.
Two patients had fracture of a flexible, open-loop, anterior chamber intraocular lens (IOL) caused by ocular trauma. Case 1 was a 78-year-old woman with a three-point-fixation IOL. The two portions of the fractured lens were removed from the anterior chamber. Visual acuity at 10 months postoperatively was hand motion as a result of corneal decompensation. Case 2 was a 36-year-old man with a four-point-fixation IOL that broke and dislocated into the vitreous. A pars plana vitrectomy was performed; the two lens portions were removed and exchanged with a sutured posterior chamber lens. Best corrected visual acuity 4 months postoperatively was 20/20. In both cases, the lens fracture took place at the loop-optic junction and with minimal visible damage to the eye structures.
