For patients with conjunctivitis, especially acute conjunctivitis, the main treatment is topical medication, with different drugs chosen for different nature of inflammation. For those who are bacterial infections, sensitive antibiotic eye drops are used, such as levofloxacin eye drops, ofloxacin eye drops, and gatifloxacin eye drops. For bacterial infections, antibiotic eye ointment is used before bedtime to prevent adhesions due to high conjunctival sac secretions. Also commonly used eye drops for viral conjunctivitis are acyclovir eye drops, ganciclovir eye drops, etc. Eye ointments, acyclovir eye ointment, ganciclovir eye ointment, etc. are also available. For acute conjunctivitis it is important to pay attention to frequent topical dots, dotted into the conjunctival sac to allow the eye medication to be fully absorbed and to have maximum effect. Also use eye ointment at night to keep its efficacy continuous, plus pay attention to isolation.
