Whatever disinfection policy your clinic follows, residual disinfectant on a tonometer tip or lens can irritate the ocular surface, so the instructions for contact time and drying matter as much as the agent. Let the agent evaporate or rinse as directed before the next patient, and keep a written protocol so staff do not improvise.
- Follow the manufacturer's contact time.
- Allow tips to dry or rinse as directed.
- Keep a written protocol staff can follow.
- Use stricter reprocessing after contact with a patient with suspected infection.
