How to set up a visual acuity session

To start a VA session the ECP must access the system via their account. In this stage the ECP and patient are not yet connected via the video call. The ECP must set up the call and invite the patient, then the patient goes through a setup process before the video call connects.

If you do not have access to the VA system you will need to contact your AOS account manager or for more information.

Starting a VA session:

  1. Log in to the AOS hub

  2. Select the patient

  3. On the patient summary page, select the ‘Visual Acuity Exam’ button (figure 1)

4. This opens the VA exam in a new browser window

5. If this is the first time using the system on your device then you must first allow the software access your device’s camera and microphone (figure 2).

Sending the patient invitation:

  1. Check the patient email address and mobile number is correct (SMS is an optional field)

  2. Select ‘Send invitation’ (figure 4)

  3. The patient will receive the invitation via email

The ECP must wait for the patient to accept the invitation and follow the setup steps, after that they will be connected to the patient. This patient set up stage could take up to 5 minutes.
