Abbreviations: n, number of eyes; %, percentage; PVR, Proliferative vitreoretinopathy (*the Chi-square test was used). Note:
Subgroup IA, subgroup in the control group with a high risk of developing PVR; Subgroup IIA, subgroup in the intervention group with a high risk of developing PVR; Subgroup IB, subgroup in the control group with established preoperative PVR grade C; Subgroup IIB, subgroup in the intervention group with established preoperative PVR grade C.
