What is a retina laser?
In principle, a laser is a very strongly concentrated source of light that, depending on physical properties, triggers a certain effect when it hits tissue. In the case of the retina laser, the laser penetrates the anterior sections of the eye without having an effect. When it reaches the retina, it has a primarily thermal reaction. This leads to a(n) (intentional) burning effect. In the case of microsecond pulsing laser therapy, in which the laser beam is pulsed very briefly onto the retina, the tissue is "heated", but not burned.
