Objective: To describe the procedure of pars plana vitrectomy (PPV) using an instrument designed for microincision vitrectomy.
Methods: In this retrospective, noncomparative, interventional case series, 6 different surgeons performed 4509 PPV procedures from August 1, 2005, through May 31, 2010, with 1-port vitrectomy using a miniaturized multifunction probe (the Intrector).
Results: Complications were reported in 20 eyes (0.44%). Culture-positive endophthalmitis occurred in 2 eyes (0.04%), sterile endophthalmitis occurred in 6 eyes (0.13%), intraoperative or postoperative retinal detachment occurred in 4 eyes (0.09%), and vitreous hemorrhage occurred in 8 eyes (0.18%). None of the 20 eyes with complications of 4509 total eyes had worse visual outcomes than preoperative visual acuity.
Conclusion: One-port vitrectomy using the Intrector is a procedure that can be used efficiently for selected cases that do not require membrane peeling.
