Those who received at least one session of therapy were analysed for safety. At each follow-up visit, the participants were asked about the symptoms and signs, including ocular symptoms (such as glare, dazzling, afterimages and flash blindness) and systemic adverse effects (such as headache or dizziness). Other information included the best corrected vision acuity (BCVA), anterior segment with slit-lamps and fundus with OCT. Additionally, each participant was also asked to report the reversible time of vision loss due to glare, dazzling, afterimages or flash blindness. Adverse events were reported based on interviews at the 12-month follow-up visit and were scored according to the common terminology standard for adverse events (CTCAE) version 5.0.
