Intense pulsed light (IPL) therapy is one of the physical therapy techniques for meibomian gland dysfunction (MGD) and MGD-related dry eye and is getting more attention from ophthalmologists in recent years. IPL therapy can improve tear-film stability, alleviate inflammatory reaction of palpebral margin, reconstruct the morphology of meibomian glands to achieve the treating goal of MGD and MGD-related dry eye by upgrading the microenvironment of meibomian gland and ocular surface tissue and reducing the inflammatory factors in ocular surface tissue based on the photothermal effect, thermal radiation effect, bactericidal action, anti-inflammatory action, light intensity modulation and restoration of the hypoxic environment of broadband incoherent light.As a novel therapy for MGD and MGD-related dry eye, IPL is recognized as effective and safe.However, there is no standardized guideline up to now for the indications, treatment parameters, operating process, treating timing, management regime and outcome evaluation because of not enough clinical evidence, a large number of equipment, many influencing factors and different parameters in the clinical practice of IPL for MGD and MGD-related dry eye.The standardized recommendation of the clinical practice of IPL is put forward in experts consensus on IPL for MGD and MGD-related dry eye (2022) by the Chinese Experts Consensus Group of IPL for Dry Eye based on extensive investigation and study.
