Name of the Procedure:

Laser treatment for inflammatory skin disease (psoriasis); also known as Excimer Laser Therapy.

Summary

Laser treatment for psoriasis uses focused laser light to target and treat the affected skin areas. This procedure helps reduce the appearance of psoriasis by slowing down the excessive growth of skin cells.

Purpose

The procedure addresses psoriasis, a chronic inflammatory skin condition characterized by red, scaly patches. The goals are to reduce symptoms, clear affected skin areas, and improve the patient's quality of life by managing psoriasis flare-ups effectively.

Indications

This procedure is indicated for patients with moderate to severe psoriasis that covers 250 sq cm to 500 sq cm of the body. It is particularly suitable for those who have not responded well to topical treatments or prefer a non-systemic option.

Preparation

• Patients should avoid sun exposure for a few days before the procedure.
• Any topical treatments should be discontinued as instructed by the healthcare provider.
• No fasting is required.
• A skin assessment will be done to determine the areas to be treated.

Procedure Description

1. The patient is positioned comfortably, exposing the treatment area.
2. Protective eyewear is provided to shield against laser light.
3. The dermatologist uses an excimer laser device to deliver focused UVB light to the psoriasis-affected areas.
4. The laser precisely targets diseased skin cells while sparing healthy skin.
5. The procedure requires multiple sessions, typically scheduled over several weeks.

Duration

Each session usually takes 10-30 minutes, depending on the size of the treatment area.

Setting

Performed in an outpatient dermatology clinic or a specialized laser treatment facility.

Personnel

• Dermatologist or trained laser technician
• Nurses or medical assistants for support

Risks and Complications

• Common risks: Redness, blistering, itching, or temporary pigmentation changes.
• Rare complications: Scarring or burning if the laser settings are not appropriately managed.

Benefits

• Reduces the appearance and symptoms of psoriasis.
• Improvement can often be seen after a few sessions, with more pronounced benefits over several weeks.

Recovery

• Minimal downtime is required; most patients can resume normal activities immediately.
• It is essential to follow post-procedure instructions, which typically include moisturizing the treated areas and avoiding direct sunlight.
• Follow-up appointments are necessary to monitor progress and schedule further treatments.

Alternatives

• Topical treatments: Creams or ointments used directly on the skin.
• Systemic treatments: Oral or injected medications.
• Phototherapy: Broad-spectrum UVB light treatments. Pros and cons exist for each alternative; for example, systemic treatments might be more effective but have more side effects.

Patient Experience

• During the procedure, patients might feel a warm or tingling sensation in the treated areas.
• Post-procedure, slight redness or irritation in the laser-treated areas is common but usually subsides within a few hours.
• Pain is generally minimal, and discomfort can be managed with over-the-counter pain relievers if necessary.
