Original title: Panuveitis with extensive retinal arteritis after delayed referral of retained lens fragments
Jun Young Park · September 2026
Leaving lens pieces inside an eye after cataract surgery can trigger extreme swelling that damages blood vessels. Doctors reported on a 61-year-old woman whose referral was delayed during the 2024 Korean medical crisis. Two months after her eye surgery, she arrived with severe eye pain, red eyes, and high pressure inside the eye. Her vision had dropped to only seeing hand motion. When doctors performed emergency surgery to clear the cloudy gel inside her eye, they found trapped lens particles. The body treated these left-behind fragments as foreign targets. This caused panuveitis, which is swelling throughout the entire eye, and extensive arteritis, which is severe inflammation of the eye's blood vessels. Surgeons removed the leftover lens material and gave her oral steroids. Her inflammation cleared up, and her best-corrected visual acuity reached 0.5 at 6-month.
Imagine cleaning a kitchen and accidentally leaving a small piece of food stuck behind a counter. Over weeks, that piece rots and attracts pests, which then spread to other parts of the kitchen, causing damage to cabinets and walls. Here, a tiny lens fragment left after cataract surgery acted like that food scrap, triggering inflammation that spread to the eye's blood vessels and threatened vision.
For cataract surgery patients, a small piece of lens left behind can trigger a dangerous inflammation that attacks the eye's blood vessels, potentially causing permanent vision loss. This case highlights why surgeons must immediately refer patients with retained lens fragments to retina specialists, especially during healthcare crises when normal follow-up may be delayed. Early detection and removal can save sight.
This is a single case report, so it cannot establish how common this complication is or prove causation definitively. The findings may not apply to all settings, especially outside the context of a healthcare crisis that delayed referral. Additionally, the patient's outcome may not be typical for all cases of retained lens fragments.
