Long before artificial tears filled pharmacy shelves, people used honey to treat wounds, burns, and infections because of its strong antimicrobial and tissue-repair properties. Now, researchers in Madrid have brought that ancient remedy into modern ophthalmology, testing whether Manuka honey eye drops could outperform the standard treatment given to patients recovering from cataract surgery.1
Dry eye disease affects a large share of adults worldwide and an even greater proportion of older populations. Cataract surgery, despite its reputation for restoring crisp vision, frequently leaves patients with burning, gritty, watery eyes that struggle with reading, screens, and bright light. For a meaningful portion of patients, that discomfort lingers for months.
Standard care typically relies on lubricating drops, steroids, and anti-inflammatory medications. These add moisture but do little to repair the damaged ocular surface driving the irritation in the first place. That’s where Manuka honey appears to behave differently.
Rather than simply wetting the eye, it seems to address the underlying problem, calming inflammation, supporting tissue repair, and protecting vulnerable tissue from microbial stress all at once. The Spanish trial put that idea to a direct test, and the results were notable enough to help explain why this old folk remedy is suddenly drawing serious scientific attention.
