There appears to be some controversy about the use of excimer laser as the first-line treatment of moderate psoriasis. Most clinical studies on the use of excimer laser therapy have focused on patients with localized psoriasis or vitiligo involving less than 10 or 20% of the body. Then, they highlight the advantages of this treatment compared to other forms of laser treatment such as narrowband UVB. However, in reality, patients with localized psoriasis, or vitiligo would typically not be considered for UV therapy since this would expose unaffected skin to the adverse effects of phototherapy.

At this stage, excimer laser therapy is an option for the treatment of psoriasis in a select group of patients. This includes patients with localized, refractory plaque psoriasis (e.g. patients with thick, scaled plaques on the knees and elbows, which are resistant to any conventional treatment).

Additionally, it is recommended for patients suffering from vitiligo for a long time since they cannot apply topical steroids for a prolonged treatment because of the side effects, especially on face and intimate areas.
