Patients preparing for infusion therapy often want to know how long their appointment will last. Treatment times can vary depending on the medication being administered and the patient’s treatment plan.
How Long Does an Ophthalmic Infusion Visit Take?
Most ophthalmic infusion appointments last anywhere from 30 minutes to 6 hours. The exact treatment time depends on the medication prescribed, the patient’s condition, and how the infusion must be administered safely.
At MERSI, patients are closely monitored throughout treatment within our dedicated ophthalmic infusion suite.
Why Do Some Infusions Take Longer Than Others?
Certain medications must be infused slowly to reduce the risk of side effects and improve patient safety.
Treatment length may vary based on:
-
- Medication type
- Dosage
- Severity of inflammation
- Patient tolerance
- Monitoring requirements
Some patients also require pre-medications before infusion begins.
What Happens During the Appointment?

A typical visit may include:
-
- Check-in
- Laboratory testing
- IV placement
- Ophthalmic examination
- Physician review
- Infusion treatment
- Post-treatment monitoring
Patients remain comfortable throughout the process while nursing staff monitor vital signs and treatment response.

Many patients receive infusion therapy every 4–8 weeks, although treatment schedules vary depending on disease severity and physician recommendations.
