Scleral fixation of the IOL was performed in seven of the eyes during first-time PPV. Visual acuity was improved in two eyes, unchanged in eight eyes, and worse in one eye. Mean corneal endothelial cell density was 2485 cells/mm2 preoperatively and 2301 cells/mm2 postoperatively. No significant differences were seen before and after the surgeries (P = 0.15, paired t-test). Intraoperative complications included retinal detachment and suprachoroidal hemorrhage in one eye each. The most common postoperative complication was transient ocular hypertension, which occurred in three eyes. IOL dislocation and vitreous incarceration of the anterior chamber in one eye required a second operation, while retinal detachment in one eye required a third operation.Conclusion: When treating a completely dislocated lens, prevention of retinal detachment which subsequently can affect the visual prognosis is the most important factor to be addressed after PPV with intravitreal phacoemulsification.Keywords: lens dislocation, pars plana vitrectomy, phacoemulsification in the vitreous cavity, retinal detachmentMutoh TMatsumoto YChikuda MDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2011, Iss default, Pp 937-940 (2011)
