Depends laser MD: The pascal theoretically causes less damage with computer generated patterns. Energy is more precise, delivered in a more preset pattern. Ower and time settings (equal to total energy delivered) tend to be less. Its wavelength 577 is absorbed by blood and the rpe. Diode is a higher wavelength and is absorbed by the rpe and choroid-the burns tend to be wider. In micropulse mode they're equal.
