What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Posterior Eyelid Temperature (Palpebral Conjunctiva) | Ocular surface temperature is usually 34.03±0.51ºC in the normal eye. The temperature required to melt obstructive secretions in the Meibomian glands ranges from 32- 35°C but the more severely obstructed glands present in MGD could require a temperature of >40°C, for effective treatment. there is an approximate 5°C difference in temperature between heat applied on the external eyelid surfaces and that reaches the inner surface of the lids, where the meibomian glands are located. This difference was due to both dissipation of heat while passing through the lid tissues and to constant movement of blood through vasculature wicking heat away from the lids. Therefore, achieving the desired temperature of 40°C at the palpebral conjunctiva requires a constant heat of at least 45°C be maintained on the outer lid surface, a temperature which could be both uncomfortable and risk causing thermal injury to the eyelid skin. | 12-minutes post treatment |
