DABRA is a minimally invasive excimer laser photoablation
system that non-thermally, photochemically ablates channels in vascular blockages.
In contrast, UV lasers utilize a "cool" photochemical or photoablation
marking process that does not require high average power levels and allows damage-free marking on many materials in a hands-free, batch process.
Xanthelasma is considered as an ideal target for laser therapy because of its superficial location.5 Therefore, different ablative and non-ablative lasers have been tried in photoablation
of xanthelasmas includes; CO2 laser,1 erbium:yttrium-aluminum-garnet (Er:YAG) laser,6 Q-switched neodymium:yttrium-aluminum-garnet (Nd:YAG) laser,7 pulsed dye laser,8 and diode laser.
annual service delivery of the spectranetics system for lead photoablation
Cancer cells take up the photosensitizers, resulting in cell death because of photoablation
. To avoid nonspecific heating of healthy cells, photosensitizers must be selectively taken up by cancer cells.

The surgical resection as emergency approach is of limited value, due to multiple lesions (>100) and the diffuse bleeding pattern; photoablation
, endoscopic electrocautery and transcatheter embolization might prove useful in this context.
Then, with the help of spatula, the flap is lifted to allow the excimer laser to perform photoablation
However, a large amount of excimer laser photoablation
may result in the deterioration of superior intrinsic corneal optical characteristic .

(13) Peyman and Katoh in 1987 used an Erbium:YAG laser for inducing photoablation
on the lens nucleus.
