Abstract: Objective To observe the clinical efficacy and safety of the non-perfusion anterior vitrectomy technique for the lens subluxation during phacoemulsification. Design Retrospective case series. Participants 20 patients (20 eyes) with intraoperative lens subluxation during phacoemulsification. Methods Under the application of viscoelastic into the vitreous cavity and cracks within the lens nucleus, no-perfusion 20 G vitrectomy headmaster from the clear corneal incision was put into the capsular bag for cutting, suction lens nucleus, cortex and anterior chamber vitreous. Viscoelastic was added during vitrectomy until full clearning lens nucleus, cortex and vitreous. Three-piece PC-IOL ciliary sulcus fixation was performed in 17 eyes in which range of dislocation was 2 quadrants or more, and CTR + PC-IOL implantation was performed in 3 eyes of less than 2 quadrants. Main Outcome Measures Visual acuity, IOP, and complications. Results There were no nuclear fall into vitreous, severe bleeding and other serious complications during the surgery. All 20 patients were implanted PC-IOL (dual loop ciliary sulcus fixation). After the first day of the surgery 7 patients with increased intraocular pressure returned to normal with treatment. At 1 month after surgery, compared with the preoperation, vision improved 2-8 lines in all patients. Vision of 10 patients (50%) was 0.5 or more. Conclusion Non-perfusion anterior vitrectomy techniques can better deal with lens subluxation during phacoemulsification, providing a new treatment choice to this complications of the intraoperation.
