OptiLight is a light-based treatment that uses precise, intense broad spectrum light to address dry eye disease due to meibomian gland dysfunction (MGD). MGD is the most common cause of dry eye disease, accounting for about 86% of cases. The treatment addresses inflammation, which is one of the key underlying factors in MGD. OptiLight was specifically developed to reach the delicate contours of the treated area safely, effectively and gently using the OPT technology.
