RESUMO
Introduction: Since the introduction of PPV (pars plana vitrectomy), techniques have improved continuously in order to provide clear and complete view of the surgical field. The present study analyzed the panoramic viewing system (PVS) Reinverting Operating Lens System (ROLS) and the plano-convex Landers lens system in PPV, and compared the surgical time, the number of lens and air-fluid exchanges, use of PFCL, scleral depression during the procedure, difficulty of laser application, final visual acuity and anatomic success. Patients and Methods: The authors retrospectively compared the records of 117 PPV, 87 patients, performed from December 1996 up to August 1998. The PPV was divided into two groups. Group 1, Landers system, included 54 surgeries, and group 2, ROLS, ineluded 63 surgeries. There were no statistical significant differences regarding pre-operative parameters, except for the initial VA Introduction: Since the introduction of PPV (pars plana vitrectomy), techniques have improved continuously in order to provide clear and complete view of the surgical field.
