Existing data beyond cataracts are scarce. This study aims to evaluate the clinical profiles, prognosis, and economic value of diverse surgeries in this monocular population to guide clinical decision-making and optimize blindness prevention strategies. Methods: This retrospective study included 308 patients with a pre-existing blind fellow eye who underwent primary inpatient intraocular surgery under a standardized clinical protocol between June 2021 and June 2025. Baseline demographics, bilateral etiologies, visual outcomes, postoperative complications, and average cost-effectiveness ratios (ACERs) were analyzed. Postoperative outcomes were evaluated for patients with at least 6 months of follow-up. Results: The primary surgical indications were cataract (51.3%), proliferative diabetic retinopathy (PDR, 19.5%), glaucoma (15.9%), and rhegmatogenous retinal detachment (RRD, 7.5%). Notably, 49.4% of patients exhibited identical blinding etiologies bilaterally. Among patients completing the 6-month follow-up (n = 109), overall mean BCVA significantly improved from 1.36 \u00b1 0.77 to 0.73 \u00b1 0.65 logMAR (p &lt; 0.001). The cataract group achieved the greatest visual improvement and the lowest ACER. Despite surgical complexity and higher complication rates, PDR and RRD interventions achieved visual improvement in over 60% of cases. Conclusions: Despite high clinical stakes, timely surgery in monocular patients yields substantial visual and economic benefits. The notable disease symmetry highlights a critical window for early intervention, emphasizing the need for public health strategies that prioritize screening progressive bilateral diseases.<\/jats:p>","DOI":"10.3390\/jcm15114041","type":"journal-article","created":{"date-parts":[[2026,5,25]],"date-time":"2026-05-25T01:45:08Z","timestamp":1779673508000},"page":"4041","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["From
