OptiLIGHT intense pulsed light (IPL) technology involves delivering energy in the form of light to the region around the eyes. The delivery of this light energy has several therapeutic effects as it improves dry eye disease by addressing meibomian gland dysfunction (MGD), reducing inflammation, improving ocular rosacea, reducing the microbial burden around the eyes, and increasing collagen production. Backed by over 70 clinical studies, OptiLIGHT IPL has become a cornerstone in the management of dry eye, as the disease is a multifactorial condition that often has several different contributing factors. This makes IPL an excellent treatment option for many patients as it addresses several of these underlying factors at once.
