25G vitrectomy: compared with the traditional 20G, it has many features such as less invasive, no suture, and less postoperative reaction, and has gradually become an optional procedure for ophthalmic surgeons in recent years. We recently completed a successful case of 25G vitrectomy for complex ocular trauma. The patient was diagnosed with traumatic retinal detachment, vitreous hemorrhage, IOL, and anterior chamber hemorrhage in the right eye. Pre-operative visual acuity: preocular light perception. A 25G vitrectomy was performed to successfully reposition the retina and remove the vitreous hemorrhage. The patient’s preoperative naked eye visual acuity: 0.1.
