Objective: To determine the effect of the Klox fluorescence biomodulation system (Phovia) on the healing of surgical wounds. Study design: Prospective, blinded, controlled clinical trial. Sample population: Healthy dogs undergoing orthopedic surgery (n = 10). Methods: Half of the length of each surgical wound was treated with Phovia, and the remaining 50% was treated with saline solution on the first day after surgery and every 3 days until day 13. Wound healing of treated and control areas within each wound was evaluated via macroscopic assessment and histo- logical and immunohistochemical analysis of treated and control wounds. Results: The areas treated with Phovia achieved lower histology scores (P = .001), consistent with complete re-epithelialization, less inflammation of the dermal layer, and greater and more regular deposition of collagen. According to immunohistochemistry, expression of factor VIII, epidural growth factor, decorin, collagen III, and Ki67 was increased in treated com- pared with untreated tissues. Conclusion: Phovia therapy improved re-epithelialization, decreased dermal inflammation, and improved matrix formation in uncomplicated cutaneous incisional wounds by regulating the expression of key biological mediators. Clinical significance: Phovia may be a beneficial adjunct to promote the healing of incisional wounds.
