Besifloxacin
A broad-spectrum fluoroquinolone antibiotic formulated exclusively as eye drops to treat bacterial conjunctivitis. It works by inhibiting bacterial enzymes needed for DNA replication and repair. Because it is not available in systemic forms, resistance development is considered lower risk.
