AIM: To explore the clinical application effect of phacofragmentation combined with vitrectomy in the treatment of traumatic lens dislocation.

METHODS: Totally 16 cases(16 eyes)of traumatic lens dislocation treated with phacofragmentation combined with vitrectomy were retrospectively analyzed, including 6 cases of high intraocular pressure(IOP)and 10 cases of vitreous hemorrhage, and 1 case of retinal detachment. All patients were given conventional flat line standard three channel vitreous operation incision to remove the anterior, middle part and peripheral vitreous around lens dislocation. The crystalline lens were drawn to the center cavity of vitreous body and treated by ultrasonic disintegrator. In the operation, the retina was examined and 8 of them had no retinal damage and in the first stage underwent fixation of posterior chamber intraocular lenses.

RESULTS: All crystalline lens dislocated were completely grinded and suctioned. There was no retinal detachment occurred in 3mo followed up. 16 eyes had normal IOP(12-20mmHg)at 1wk after operation. The average visual acuity was improved and with 8 cases got improved of 0.2 or more 1wk after operation.

CONCLUSION: Our research shows that phacofragmentation combined with vitrectomy is a safe and effective method for the treatment of traumatic lens dislocation. The patients with nondestructive retina in the operation are feasible to do first stage operation of intraocular lens suture fixation, which contributes to the best visual acuity.
