# Bacterial keratitis treatment

[Bacterial keratitis is a sight-threatening corneal infection](https://bluefinvision.com/blog/what-is-keratitis-causes-symptoms-and-treatment/) that needs urgent treatment. Prompt intensive antibiotics aim to clear infection and minimise scarring.

## Immediate management

Diagnosis is based on examination and sometimes corneal scraping for culture. Treatment usually starts straight away, even before results return.

- Frequent antibiotic eye drops, often hourly at first
- Broad-spectrum or fortified antibiotics chosen for likely organisms
- Pain relief, cycloplegic drops, and close follow-up
- Adjustment of therapy once culture results and response are known

## Preventing complications and recurrence

Careful monitoring helps detect thinning, perforation, or spread. After healing, long-term strategies reduce future risk.

- Regular checks for scarring and astigmatism affecting vision
- Safe contact lens habits and avoidance of overnight wear
- Treatment of lid disease or trauma that predisposed to infection
- Protective eyewear for high-risk work or sports
