Purpose: To evaluate the risk of diabetic retinopathy (DR) progression and associated ophthalmic complications after YAG laser capsulotomy in patients with nonproliferative DR (NPDR) after cataract surgery. Setting: Multicenter study using deidentified electronic health records from 69 U.S. healthcare organizations across outpatient and academic ophthalmology settings. Design: Retrospective cohort study using propensity score matching to balance baseline characteristics. Methods: Patients aged 18 years or older with type 1 or 2 diabetes and NPDR who underwent cataract surgery with or without subsequent YAG laser capsulotomy were identified. Patients were followed for 1-year postcataract surgery. Exclusion criteria included less than 6 months of follow-up. Primary outcomes included development of proliferative DR (PDR), vitreous hemorrhage (VH), tractional retinal detachment (TRD), neovascular glaucoma, and need for panretinal photocoagulation (PRP) or pars plana vitrectomy. Results: 10 750 patients (10 750 eyes) were included after matching: 5375 YAG-treated and 5375 control eyes. At 1 year, YAG-treated patients had higher risk of PDR (hazard ratio HR, 1.91; 95% CI, 1.67-2.18), VH (HR, 1.40; 95% CI, 1.15-1.72), TRD (HR, 2.04; 95% CI, 1.32-3.13), and PRP (HR, 1.48; 95% CI, 1.14-1.91). A secondary analysis of patients with ≥5 years of NPDR showed similar elevated risks. Conclusions: YAG laser capsulotomy in patients with NPDR is associated with increased risk of DR progression and vision-threatening complications. Ophthalmic screening and close follow-up are recommended in this population after YAG treatment.
