TRAUMATIC FRACTURE OF FLEXIBLE ANTERIOR-CHAMBER INTRAOCULAR LENSES

Two patients had fracture of a flexible, open-loop, anterior chamber i ntraocular lens (IOL) caused by ocular trauma. Case 1 was a 78-year-ol d woman with a three-point-fixation IOL. The two portions of the fract ured lens were removed from the anterior chamber. Visual acuity at 10 months postoperatively was hand motion as a result of corneal decompen sation. Case 2 was a 36-year-old man with a four-point-fixation IOL th at broke and dislocated into the vitreous, A pars plana vitrectomy was performed; the two lens portions were removed and exchanged with a su tured posterior chamber lens. Best corrected visual acuity 4 months po stoperatively was 20/20. In both cases, the lens fracture took place a t the loop-optic junction and with minimal visible damage to the eye s tructures.
