After vitrectomy, the dropped lens nucleus was floated on the perfluorocarbon liquid (PFCL). The floating lens nucleus was then phacoemulsified and aspirated. During surgery, irrigation from the anterior chamber was performed. This method was very effective for treatment of a dropped hard nucleus.Case report: During cataract surgery on the left eye of an 80-year-old woman, a posterior capsule rupture occurred. As a result, the lens nucleus dropped into the vitreous cavity. Irrigation to the anterior chamber was performed, with an anterior chamber maintainer inserted through a newly created side port at the corneal limbus. A vitreous cutter and a light guide were inserted in order to perform vitrectomy through the corneal incisions that were created for the cataract surgery. After vitrectomy, the dropped lens nucleus was floated using PFCL. The floating lens nucleus was removed by a bimanual phacoemulsification technique, with the anterior chamber irrigation continuing. The separation of the irrigation port and the aspiration port allowed for effective treatment of the dropped nucleus that was floating on the PFCL, even using a phacoemulsification machine with a peristaltic pump system. Safe and effective vitrectomy, similar to a PPV, could be performed with this method using three corneal ports.Conclusion: This technique may allow safer and more effective treatment for a dropped lens nucleus compared with conventional PPV. With this technique, corneal distortion due to surgical manipulation can lead to reduced visibility of the posterior eye.
