Objective To investigate the application and effect of bimanual nucleus chopping combined with intracapsular infusion for in situ ultrasonic phacofragmentation in vitreoretinal surgery in order to explore the efficient,safe and maintain the lens in situ techniques of ultrasonic phacofragmentation.Methods Fifty-six patients (58 eyes) who were in need of vitrectomy with lens opacities or vitreous surgeries with anterior proliferative vitreoretinopathy which the joint vitreous surgeries were required to remove the lens.Among them,there were 31 complicated retinal detachment eyes,14 proliferative diabetic retinopathy eyes (stage Ⅴ~Ⅵ),7 vitreous hemorrhage eyes,6 preceding proliferative vitreoretinopathy eyes.The nucleus hardness were grade Ⅲ~Ⅳ.During the surgery,irrigation catheter was placed in the vitreous cavity and the perfusion was turned off at first,the 9#(20G) needle head with perfusion and the sonicate head (Millennium) were inserted into puncturing sites of bimanual vitrectomy,separately.Then the following procedures were performed:pierced the anterior capsule,hydrodissected the lens with perfusion and grooved with ultrasound,then the nucleus was chopped bimanual using the "cross-type" method,the nucleus was divided and phacoemulsificated,fragmentations of nucleus was squeezed and sent to the sonicate head with bimanual collaboration.After the cortex and the nucleus were completely removed,vitrectomy began with vitreous cavity perfusion on.Thirty-three eyes which needed the combined intraocular silicone oil tamponade surgeries were removed of anterior and posterior lens capsules completely,the posterior capsules of the other 25 eyes were retained.The ultrasound time and energy were recorded.Results The lens could be removed in situ with the posterior capsules intact in all cases; in addition,the anterior chamber depth was able to be maintained stably.During the surgeries,no black diaphragm moved back and forth,no lens nucleus sank into vitreous cavity and no cornea puncture,sclera puncture and iris were injured.Those 25 eyes which retained the intact posterior capsules would be implanted of posterior chamber intraocular lenses 1 to 3 months after the first surgeries,all subjects showed improved vision of various degrees after surgery.The entire procedure was convenient,fast and efficient.The average ultrasound time was 45.5s and the maximum ultrasonic energy was set at less than 12%.Conclusions Bimanual nucleus chopping combined with intracapsular infusion method is effective for the in situ ultrasonic phacofragmentation,the surgery is fast,has less injury and great clinical applicability.
