PDT is an attractive method of treating skin cancers without surgery and with excellent results aesthetically, but its widespread implementation has been held up by high costs.

The specialised light sources required were very expensive and could not be used for anything else. Swiss companies have taken the lead in non-laser phototherapy and Q.Products AG makes the largest range of flexible and specialised non-laser devices.

The flexible model for medical professionals who require a wide range of treatment options now has the capability to deliver the correct wavelengths of red, incoherent polarised light necessary to activate photosensitising creams such as Metvix® for PDT and also has a blue diagnosis filter which is used with a revealing cream to help identify lesions. There is also a new dedicated model for skin cancer specialists.

The Q.Light PRO is a modular device using filter modules of different characteristics to treat a wide range of medical conditions.

With the new diagnosis and PDT treatment filter modules this reduces the cost of PDT equipment substantially, making treatments more viable financially.

• Diagnosis: blue light 385-450nm
• PDT Treament: red, incoherent polarised light, 620 - 780nm

Other optional filter modules allow phototherapy treatments of dermatological conditions, e.g.psoriasis and acne, acute or chronic wounds and further conditions (see pages from this web site).

Together these make Q.Light PRO a highly attractive and flexible device for dermatologists and skin cancer specialists with the capability of taking on new functions as required.

Choice of Stands Clinics, surgeries and practitioners operating in confined spaces can use the neat and sturdy Regular stand, with five casters for stability (with brakes for smooth floors), an adjustable arm and swivel ball joint for the head. This allows a great variety of positions and angles for the head whilst taking up very little valuable floor space.

Hospitals and larger clinics, especially those where over-bed use is desired will appreciate the PRO-Plus stand with extended cantilever arm and extra storage (additional lower shelf and storage basket not shown).
