The possibility of persistent fungal infections of the cornea should be considered after prolonged steroid dosing.
Prolonged use may result in overgrowth of nonsusceptible organisms, including fungi. If superinfection occurs, appropriate therapy should be initiated.
If purulent discharge, inflammation, or pain becomes aggravated, the patient should discontinue use of the medicatioin and consult a physician.

Mode of Action
Neomycin, an aminoglyoside with antimicrobial spectrum similar to gentamicin, binds to the 30S subunits of the bacterial ribosome, inhibiting protein synthesis and thereby disrupting DNA synthesis. It is active against many gram-negative aerobes and against some strains of staphylococci.
Prednisolone decreases inflammation by inhibition of migration of polymorphonuclear leukocytes and reversal of increased capillary permeability. It suppresses the immune system by reducing the activity and production of the lymphocytes and eosinophils.
