Patients and Methods: Fourty two eyes of 42 consecutive patients with RRD were in-cluded in the study. All patients underwent 23G pars plana vitrectomy. Phakic patients underwent phacoemulsification and intraocular lens implantation at the same setting if they are in the presbyopic age, or they have a high refractive error. Following central vitrectomy and removal of anterior hyaloid perfluorodecaline was injected if there was Grade C PVR, if the detachment was bullous, or if the macula was completely detached. Following heavy perfluorocarbon liquid injection vitrectomy was performed up to the vitreous base. Anteri-or subretinal fluid was drained via existing holes and perfluorodecaline was removed with fluid-air exchange. Subretinal fluid was drained from posterior drainage retinotomy under air in surgeries without perfluorodecaline use. Vitreous base shaving was made under air in all eyes up to just anterior to ora serrata.Results: Fifteen woman and 27 man was included in the study. Twelve of 19 phakic eyes underwent phacoemulsification and lens implantation at the same setting. Patients were followed for 6.5±4 months. Only 5 eyes had Grade C PVR. Perfluorodecaline was used in 13 (31%) eyes peroperatively. Silicone oil was used as tamponade in 19 eyes, and C3F8 gas was used in the remaining 23 eyes. Redetachment was developed in 4 (9.5%) eyes. Redetachment was due to anterior PVR in 2 cases and was related to drainage retinotomy in the other 2 cases. Complete reattachment was obtained in 3 of these cases and shallow detachment anterior to the equator persisted in the other case after repeat surgeries. Acci-dental peripheral holes was created in 2 eyes peroperatively. Increased IOP was detected in 5 eyes, and fibrin reaction developed in 3 eyes postoperatively. Conclusion: Vitreous base shaving under air in eyes with retinal detachment is a safe and effective method. It has a high success and low complication rate. Scleral indentation is not necessary during surgery. It also decreases the need for heavy perfluorocarbon fluid use and the disadvantages due to its use.
