The disruption of oil glands in our eyelids known as Meibomian glands, which produce the oily layer of our tears to protect it from evaporating, is one of the most common contributors of dry eye disease. Much effort has been put into developing effective treatments for this condition as new treatments are constantly being introduced to the market.\n\nThe purpose of this clinical trial is to investigate how proven light-based therapies work in treating dry eye disease and oil gland disruption. These therapies include intense-pulsed light therapy (IPL) which uses a series of light flashes on the facial skin surface, and low-level light therapy (LLLT) which uses a mask with a series of light-emitting diodes (LEDs) to warm the body cells. The main questions it aims to answer are:\n\n1. What are the short- and long-term changes associated with these treatments on the eyelids and surface of the eyes?\n2. Does LLLT alone work better than IPL+LLLT in treating dry eye disease and oil gland disruption?\n\nParticipants with dry eye disease and oil gland disruption will receive four treatments with these light-based therapies each separated by two to three weeks apart, and followed up two to three weeks and three months after the final treatment session. One eye of the participant will receive intense pulsed light together with low-level light therapy, while the other eye will receive only low-level light therapy with a sham intense pulsed light treatment so that the researchers can compare if clinical signs and symptoms improve in one eye more than the other.', 'detailedDescription': 'This study will be a randomized, double-masked, paired-eye clinical study to assess the potential difference in impact between the two treatment modalities. Each eye of the participant will be randomized to receive either IPL+LLLT or sham IPL+LLLT. The whole study involves a total of 6 visits (consisting of 4 treatment visits, and 2 follow-up visits).
