The Importance of High-Quality Cataract Surgery: A Case of Objective Improvement in Post-surgery Outcomes at a Rural Hospital in Vietnam.

The Socialist Republic of Vietnam, with a population of approximately 100 million, faces a critical shortage of ophthalmologists with only 1,300 practitioners nationwide (1.3 per 100,000 population). Cataracts remain the leading cause of blindness, accounting for over 75% of cases. While volunteer cataract surgery programs operate throughout the country, resource limitations often preclude comprehensive pre- and post-operative assessments, including standardized visual function testing. We report a case from a rural Vietnamese hospital, demonstrating significant objective visual improvement after cataract surgery, which highlights both the challenges and the public health significance of surgical outreach in resource-limited settings. An 86-year-old Vietnamese woman presented with vision loss and no documented medical or ophthalmic history. She underwent volunteer-based cataract surgery on her right eye. Preoperative findings included uncorrected visual acuity of 0.03 (20/667), intraocular pressure (IOP) of 13.0 mmHg, and a dense nuclear sclerotic cataract (grade 4-5) precluding fundoscopic examination. Phacoemulsification with intraocular lens (IOL) implantation was performed without complications. Postoperative management included topical antibiotics and overnight patching. On postoperative day one, the patient's uncorrected visual acuity improved to 0.6 (20/33). IOP was 14.0 mmHg, and findings included mild anterior chamber inflammation, well-centered IOL, and a clear fundus view with normal macula and optic disc morphology. This case highlights that cataract surgery in a rural, low-resource setting can result in substantial visual improvement, even in advanced cases. It emphasizes cataracts as a leading cause of reversible blindness in Vietnam and demonstrates the transformative impact of surgical outreach. Expanding access and training are essential to address unmet ophthalmic needs in underserved regions.
