Endophthalmitis after pars plana vitrectomy with reused single-use devices: a 13-year retrospective study.

The rate of endophthalmitis in patients who underwent 23-gauge PPV was comparable to those who underwent 25-gauge PPV. With our standardized protocol for instrument sterilization, endophthalmitis rates in those undergoing PPV using recycled single-use instruments were within the range of previously published results in which vitrectomy tools were disposed of after one use.
