LASER: Types, Indication, Contra-indication, Therapeutic Effect & Dangers
It is an acronym from the words light amplification stimulated emission radiation. Treatment unit may combine a helium neon laser which produces the red light beam at 630nm with an infrared laser at 940nm.
This combination allows the infrared part of the beam to penetrate quite deeply into the tissue without producing heat.
Types of Laser
- Power Laser – It is used for the destructive or surgical purpose.
- Soft Laser – It has a very superficial effect and is used principally for treating the skin.
- Mid Laser – Its depth of penetration is sufficient to produce the biological effect on deeper tissue without damaging.
Physiological effect of Laser
- Wound healing
- Analgesic effect
- Normalization of tissue
- Endorphin release
- Re-absorption of edema fluid.
- Coagulation of proteins.
Indication of Laser
- Open lesions

- Cardiac patient
- Patient with a pacemaker
- Skin disease
- Pregnant women
- Growing cartilage in children.
- Directly eyes.
Dangers of Laser
- Eye damage if the beam is applied directly to the eye.
- There is no thermal effect in the skin.
