Doctor's answer:
0.1% rifampicin or 0.5% chlortetracycline or tetracycline eye drops are effective when applied 3 to 6 times daily. However, these drugs gradually lose their efficacy within a few weeks after dissolving in water and need to be reprepared. If formulated as eye ointment or suspension, they can be stored for a longer period. 10% to 30% sulfacetamide sodium and 0.25% to 0.5% chloramphenicol eye drops are easy to preserve and also highly effective.
