    5 things you need to know about TFOS DEWS II

    TFOS DEWS II report is here. It will take some time to get through and absorb, but I have a few initial thoughts.

    I am happy to see in TFOS DEWS II:

    • The recognition that dry eye is “loss of homeostasis” can help guide our strategies in treating our patients. Many extrinsic and intrinsic factors can disrupt the tear film. We hope to return homeostasis to the lacrimal function unit

    • Acknowledgment of the neuro sensory component, our “pain without stain” patients, can lead to future research and perhaps better treatment options for these patients who are frustrated and frustrating at the same time

    • Recommendations that we investigate the seemingly increased prevalence of dry eye disease among youth and look into device use as a potential cause

    • Clarify that evaporative dry eye (EDE) and aqueous-deficient dry eye (ADDE) are not mutually exclusive. This clarification will encourage practitioners to treat dry eye disease more completely and may lead to better outcomes
