The idea is to maximize each drop’s absorption by using the correct sequence and timing when giving multiple ophthalmic drops to the same eye. Wait at least 5 minutes between drops so the first drop can be absorbed rather than being washed away or diluted by the next drop. Apply all drops before using any ointment, because ointment creates a barrier and can delay or reduce the absorption of subsequent drops or blur vision; applying drops first ensures they reach the cornea effectively. Also, document what was given, in what order, the exact times, and when ointment was added so the care team has a clear record for safety and future treatments.
