Intense pulsed light treatment in meibomian gland dysfunction

Dry eye disease (DED) associated with meibomian gland dysfunction (MGD) is a chronic and progressive disease that can cause numerous eye symptoms, such as discomfort, irritation, stabbing, and vision disturbances. Previously used treatment methods are insufficient for some patients. The article describes the indications, method of performing, mechanisms of action, and effectiveness of intense pulsed light (IPL) regarding available literature. The technique involves using a series of impulses of non-coherent, polychromatic broad-bandwidth wavelengths in the periorbital area to the skin around the eyes and eyelids. Numerous studies have shown the effectiveness of IPL for MGD, a decrease in symptoms connected with DED assessed by Ocular Surface Disease Index (OSDI) questionnaire, an increased tear break-up time (TBUT), and improvement of meibomian glands function indicators
