Clinical observation of dropped nucleus during phacoemulsification

ObjectivesTo report the incidence，clinicfeatures and management of dropped nucleus during phacoemulsification.MethodsAretrospective review of the postoperative conditions of 10 patients who had lens nucleusdropped into vitreous during phacoemulsification.ResultsOf the 4400 patients withcataract who underwent phacoemulsification，lens nucleus dropping into vitreous occurredin 10 patients（0.23％）.After dropping of lens nucleus IOP elevated in all 10 patients（100％）.Postoperatively，thebest corrected visual acuity（VA）of 3 patients with dislocation of smaller than 25％of lens material and primary AC-IOL placement during KPE was 0.5 or better，while that of4 patients who underwent vitrectomy within 2 weeks after KPE was 0.4 or better，and thatof 3 patients with dislocation of greater than 50％ of lens material and withoutvitrectomy was 0.01 or worse.ConclusionsSmall pieces of retained lens fragments invitreous（<25％）may allow AC-IOL implantation and surgical removal may not berequired.If greater than 50％ of lens material was dislocated into vitreous，surgicalremoval of dislocated crystalline lenses must be performed，otherwise，it may result invery poor visual outcome.In most patients with retained lens fragments in the vitreousduring phacoemulsification，vitrectomy allowed good visual acuity outcomes，and it wasthe only correct method of managment.
