AIM: To retrospectively analyze the surgical strategies and outcome of traumatic lens dislocation.

METHODS: Retrospective study. Clinical data of 105 cases(105 eyes)diagnosed with traumatic lens dislocation from April to June 2014 in our hospital were recruited. According to position of dislocated lens and complicated situations, different surgical approaches were performed, including intracapsular lens extraction, phacoemulsification, vitrectomy through pars plana and lensectomy.Meanwhile, vitreo-retinal or anti-glaucoma surgeries were performed in complicated cases.Preoperative and postoperative LogMar(Logarithm of the Minimum Angle of Resolution)visual acuity were compared by paired t-test. Perioperative complications including expulsive choroidal hemorrhages and recurrent retinal detachment were recorded and assessed.

RESULTS: All 105 dislocated lenses were removed completely. Visual acuity of 91 eyes(86.7%)were significantly improved postoperatively.The visual acuity of most patients was 0.1-0.3(42 eyes, 40.0%)and 1 patient's visual acuity with lens subluxation reached more than 0.8 postoperatively. Expulsive choroidal hemorrhages occurred in 1 eye intraoperatively and 1 eye postoperatively. Recurrent retinal detachment was observed in 2 eyes postoperatively.

CONCLUSION: According to position of the lens dislocation, personalized surgery strategy is critical for therapy of traumatic lens dislocation.Expulsive choroidal hemorrhage is one of most several complications and should be managed properly.
