Intravitreal bimanual surgery for residual lens fragments and displaced crystalline lenses

The authors have developed a new technique for removing large and hard lens fragments or crystalline lenses with hard nuclei dislocated into the vitreous cavity using an optic fiber-free intravitreal surgical system (OFFISS). The OFFISS visualizes the fundus without a fiberoptic and facilitates the bimanual technique. The lens materials are stabilized with one hand and the fragmatome to emulsify the lens fragments is controlled with the other. The lens fragments or subluxated crystalline lenses can be removed through 20-gauge incisions. This technique was used in 14 cases and was found to be safe and not invasive.
