IPL (Intense Pulse Light) is an effective dry eye treatment which uses a flash lamp that pulsates a high intensity light at selected wavelengths on the treated skin area around the eyelids. It is a technology that has been used in dermatology for a few decades. In 2002, Dr Rolando Toyo discovered the benefit of IPL in treating dry eyes whilst treating his patients who suffers from rosacea. Subsequently, Toyo had developed the protocol of treating dry eyes with IPL.
