A sterile burr is a small, drill-like ophthalmic instrument used to remove rust rings or embedded foreign bodies from the cornea. It’s typically single-use, precision-engineered, and comes pre-sterilized to prevent infection.
Here’s the step-by-step usage:
- Numb the eye with topical anesthetic drops.
- Position the patient comfortably under a slit lamp for magnification.
- Stabilize the eye using a lid speculum or gentle pressure.
- Activate the burr (usually battery-powered) and gently apply it to the rust ring or foreign body.
- Rotate lightly to scrape away the material without pressing too deep.
- Irrigate the eye to flush out debris.
- Apply antibiotic ointment and possibly a patch for comfort.
- Advise on aftercare — typically antibiotic drops, no rubbing, and follow-up if pain or vision changes persist.
