Topical antibiotic therapy uses eye drops or ointments applied directly to the eye or eyelids to treat bacterial infections or prevent infection after surgery. It delivers high local concentrations with limited systemic exposure.
Uses
Topical antibiotics are prescribed for bacterial conjunctivitis, corneal ulcers, lid margin infections, and prophylaxis around ocular procedures or injuries. Different agents and formulations target a range of organisms.
- Ointments provide longer contact time but can blur vision temporarily
- Combination antibiotic-steroid drops may be used cautiously in selected inflammatory conditions
- Contact lens wear is usually stopped during treatment
- Course duration depends on severity and response
Considerations
Correct application technique and adherence to dosing are important for success. Overuse or inappropriate use of antibiotics can contribute to resistance and allergy.
- Stinging or mild irritation on instillation is common but should not be severe
- Patients should avoid sharing bottles and touching the dropper tip to the eye
- Review is needed if symptoms worsen or fail to improve as expected
- Some preparations contain preservatives that may aggravate dry or sensitive eyes
