Press the "Confirmation" button on the touchscreen (Figure 10).
Treatment Procedure
The treatment will consist of 4 phases:
1. The treatment initiates with 35 seconds of pulsed yellow and near-infrared (NIR) wavelengths,
eyes open.
2. This is followed by 90 seconds of continuous red light wavelength, eyes closed.
3. The treatment will repeat with another 35 seconds of pulsed yellow and NIR wavelengths, eyes
open.
4. The treatment will finish with another 90 seconds of continuous red light wavelength, eyes closed.
The operator will instruct the patient to keep their eyes open during phases 1 and 3 and then to
keep their eyes closed for phases 2 and 4.
