Abstract Purpose To compare the long-term incidence of recurrent vitreous hemorrhage(VH) and neovascular glaucoma (NVG) in patients with proliferative diabetic retinopathy (PDR) undergoing pars plana vitrectomy (PPV) alone versus combined PPV and phacoemulsification (PPV 95% CI, 0.40–0.92), while severe preoperative traction was a major risk factor (aHR, 2.24; 95% CI, 1.39–3.60). For NVG development within two years, the surgical approach was not a significant factor. Instead, severe preoperative traction (aHR, 5.88; 95% CI, 1.67–20.68) and older age (aHR, 1.06; 95% CI, 1.01–1.11) were the primary independent risk factors.These findings were confirmed in a 1:1 age-matched PSM cohort. Conclusion Combined PPV with phacoemulsification is associated with an increased risk of recurrence within the first two postoperative years but does not increase the risk of neovascular glaucoma. The severity of baseline proliferative disease, particularly the degree of traction, is a more critical determinant of postoperative complications than the surgical strategy regarding the lens. This supports tailoring the surgical approach based on individual patient cataract status and retinal pathology.
