Laser therapy
Laser therapy for wound healing uses targeted light energy to stimulate tissue repair, reduce inflammation, and accelerate recovery. It’s especially effective for chronic wounds like diabetic ulcers, pressure sores, and post-surgical incisions.
Here’s a detailed look at how it works and its clinical benefits:
What Is Laser Therapy in Wound Care?
Laser therapy—particularly Low-Level Laser Therapy (LLLT) or photobiomodulation—involves applying low-intensity laser light to the wound area. This light penetrates the skin and interacts with cells to:
- Stimulate ATP production for cellular energy
- Enhance collagen synthesis for tissue strength
- Increase blood flow and oxygenation
- Reduce inflammation and pain
- Accelerate epithelialization and tissue remodeling
These effects help wounds heal faster and more effectively.
Types of Lasers Used
- Class III lasers: Used for superficial wounds and pain relief
- Class IV lasers: Higher power, suitable for deeper tissue stimulation
- IMDSL Laser Therapy: A specific system used in India for wound healing and post-surgical recovery
Conditions Treated Laser therapy is beneficial for:
- Diabetic foot ulcers
- Venous leg ulcers
- Pressure sores
- Surgical wounds
- Burns
- Traumatic injuries
It’s often used as an adjunct to standard wound care, not a standalone treatment.
Safety and Considerations Laser therapy is generally safe when administered by trained professionals. However:
- Eye protection is mandatory
Contraindicated over cancerous lesions or pregnancy-related areas
Not suitable for patients with light sensitivity disorders
Treatment Protocol
- Sessions typically last 10–30 minutes
- Frequency ranges from daily to weekly, depending on wound severity
- Results may be seen within a few sessions, especially in chronic wounds
