‘Photodynamic therapy light’: An enhanced treatment protocol for actinic keratoses with minimal pain and optimal clinical outcome by combining laser-assisted low irradiance PDT with shortened daylight PDT

The novel 'PDT light' protocol proved to be an excellent and nearly painless method with an average visual-analogue scale (VAS) score of 1.19. Additional advantages included reduced illumination time, shorter outpatient stays in the clinic, fewer adverse effects, and better patient compliance than with DLPDT alone.
