Corticosteroid Eye Drops: What They Are, How They Work, and What to Watch For

When your eyes are red, swollen, or burning from inflammation, corticosteroid eye drops, a powerful class of anti-inflammatory medications used to treat eye conditions like uveitis, allergic conjunctivitis, and post-surgery swelling. Also known as steroid eye drops, they work by calming down your immune system’s overreaction in the eye tissue. These aren’t your everyday lubricating drops—they’re prescription-only tools that can bring quick relief, but only if used exactly as directed.

They get absorbed into your body, which is why long-term use can raise eye pressure, cause cataracts, or even lead to glaucoma. That’s why doctors don’t hand them out like candy. If you’ve been on them for more than a few weeks, your eye doctor will likely check your pressure regularly. And if you’re using them for something like seasonal allergies, you should know that they’re not meant for daily, long-term use—there are safer options for that.

But if you’re using them without a clear diagnosis, you’re playing with fire. These drops can mask infections, letting something like bacterial keratitis grow unnoticed until it’s too late. And if you’re on systemic steroids like prednisone, your eye doctor needs to know—it can change how they approach your treatment. eye inflammation, the main reason these drops are prescribed isn’t always obvious.
