What Is Laser Therapy (LLLT)?
Low-level laser therapy (photobiomodulation) uses specific wavelengths of red and near-infrared light to stimulate biological healing processes in cells without cutting, heating, or damaging tissue. The photonic energy is absorbed by cellular mitochondria, boosting ATP synthesis and activating gene expression pathways that regulate inflammation, cell proliferation, and matrix synthesis. For wound healing, this translates into faster formation of granulation tissue, improved wound contraction, and stronger scar tissue.
How Laser Therapy Promotes Wound Healing and Post-Surgical Recovery
Wounds — whether surgical incisions, traumatic lacerations, or chronic ulcers — require fibroblast activity to close and produce collagen. LLLT increases fibroblast proliferation and migration into the wound bed by up to threefold in research models. It also stimulates angiogenesis (new blood vessel formation) that delivers the oxygen and nutrients the wound needs to close, and reduces bacterial biofilm formation in chronic wounds. Post-surgical scars treated with LLLT mature faster, are softer, less raised, and less prone to adhesion formation.
What to Expect During Treatment at Realign Rehab Clinic
Dr. Vaishali Suri at Realign Rehab Clinic, NIT-5 Faridabad, positions the laser handpiece a few centimetres above the wound or surgical scar and applies energy in a systematic grid pattern covering the entire wound bed and surrounding tissue. Protective eyewear is worn by both patient and therapist. A session takes five to fifteen minutes and is completely painless. For acute post-surgical wounds, treatment typically begins once the wound is clean and closed — usually five to seven days post-surgery — and continues two to three times per week for four to six weeks. Chronic non-healing wounds may require longer or more intensive treatment.
Benefits of Laser Therapy for Wound Healing
- Accelerates wound closure and granulation tissue formation
- Reduces scar thickness and improves scar pliability
- Decreases post-surgical swelling and bruising
- Reduces risk of chronic wound complications and adhesion formation
Is Laser Therapy Safe?
LLLT is safe for use on post-surgical wounds and chronic wounds when proper wavelength and dose parameters are observed. Eye protection is mandatory throughout. It should not be applied over active malignancy, infected wounds with spreading cellulitis (until antibiotic treatment is established), or over the pregnant uterus. LLLT is not a substitute for proper wound debridement or medical management of infected wounds. Dr. Vaishali Suri coordinates with treating surgeons for post-surgical cases.
Frequently Asked Questions
Does laser therapy hurt?
Laser therapy is entirely painless over wound sites. Patients who are tender around a fresh surgical scar are often surprised by how comfortable the treatment is. There is no contact required — the handpiece is held above the wound, and no pressure is applied to sensitive tissue.
How many sessions of laser therapy will I need?
Post-surgical wounds typically benefit from eight to twelve sessions over four to six weeks. Chronic wounds or complex scars may require twelve to twenty sessions. Dr. Vaishali Suri monitors wound dimensions and tissue quality at each visit to track progress.
Is laser therapy available in Faridabad?
Yes. Laser Therapy (LLLT) is available at Realign Rehab Clinic, NIT-5 Faridabad. Dr. Vaishali Suri uses this technique as part of a comprehensive physiotherapy programme. Call +91 9818185589 to book.
