Laser Therapy

Lasers are being successfully used for a wide range of therapeutic procedures. Deep tissue therapy is used to relieve pain, accelerate healing and decrease inflammation.  PhotoDynamic Therapy (PDT) can be used to target and destroy cancer cells while Intralesional-PDT (I-PDT) is a form of PDT which has been developed specifically for the treatment of lesions, both internal and external.

PhotoDynamic Therapy (PDT) 

PDT is a type of photochemotherapy which uses the phototoxic effect of photosensitising drugs on cancer cells. The photosensitising drug makes cells more sensitive to light and is attracted to the cancer cells. It does not become active until it is exposed to a particular type of light, usually a high-intensity laser light of a very specific wavelength. The drug is activated when this light is directed at the area of the cancer, usually by means of a flexible optical fibre or a special lamp. The energy in the light activates the drug, which destroys the cancer cells by combining with oxygen to form a short-lasting substance that is toxic to the cells. 

All our lasers are suitable for PDT when used with a long diffusing fibre tip to apply laser light evenly over a wide area. Excel Lasers is a UK distributor for Medlight’s range of specialist diffuser fibres which can be used in a number of PDT applications and with lasers of various wavelengths. We currently support the most popular wavelengths of 630, 635, 652 and 670 nm, which are used with photosentitiser drugs such as Photofrin, ALA and Foscan. Applications include lung cancer, oesophageal cancer, head and neck cancers.

Deep tissue therapy

Laser Therapy has been successfully used to treat a broad range of medical conditions, including musculoskeletal problems, arthritis, sports injuries, post-surgical wounds, diabetic ulcers and dermatological conditions.Laser therapy is used to stimulate the cell to perform its natural functions, but at an enhanced rate. 

Benefits of deep tissue therapy

  • Promotes faster healing
  • Reduces pain
  • Restores normal range of motion and physical function  
  • Treatment is easy, painless, non-invasive and non-toxic
  • Can make surgical interventions unnecessary 


Intralesional-PDT (I-PDT) is a recent development from INTERmedic particularly targeted at dermatological conditions.

I-PDT is a selective, minimally-invasive treatment using a photosensitive drug which is activated by being irradiated with laser light to selectively destroy pathogenic cells while preserving the healthy ones. It is also used to treat lesions internally and has proven clinical efficacy in a wide range of applications.

Benefits of I-PDT

  • Does not alter adjacent tissue and organs
  • Topical and Intralesional drug administration
  • No side effects
  • Safe, effective and minimally invasive therapy
  • Fast, comfortable procedures with no downtime.
