What Foods Are Beneficial for Filamentary Keratitis?

Patients with filamentary keratitis should follow a light yet nutritious diet, consuming abundant vegetables and fruits rich in vitamins and dietary fiber. Soy products, lean meats, and eggs—foods high in calories and high-quality protein—support corneal repair. Patients should correct unhealthy dietary habits: actively quit smoking and alcohol consumption, and minimize or avoid fried, spicy, greasy, and high-sugar foods—such as chili peppers, fatty meats, fried dough sticks (youtiao), and cream. Additionally, patients should protect their eyes and avoid eye strain—especially refraining from prolonged use of computers, smartphones, or televisions late into the night. Eye hygiene is also essential; never rub your eyes with unwashed hands.

Filamentary keratitis commonly results from prolonged wear of contact lenses—including cosmetic or “iris-enhancing” lenses—or extended eye patching, all of which cause corneal epithelial hypoxia, dryness, degeneration, and desquamation. Degenerated and shed corneal epithelial cells combine with mucus to form fine filaments directly on the cornea, leading to photophobia, tearing, and foreign-body sensation. When filaments are present, topical anesthetic drops (e.g., proparacaine) should first be administered. Subsequently, filaments may be gently removed using a cotton-tipped applicator or an ophthalmic foreign-body spud, followed by application of antibiotic ointment for 12–24 hours. Preservative-free artificial tears—and medications specifically designed to protect and promote healing of the corneal epithelium—should also be instilled daily.

Patients are advised not to rub their eyes with unclean hands or overuse their eyes; any discomfort warrants prompt medical evaluation. We hope this information proves helpful.
