Summary

Objectively evaluate the ocular surface (pre-corneal tear film) of individuals prior to and after an intervention (such as a dry eye treatment, environmental change, artificial tear use, or contact lens wear) in a controlled-environmental chamber, over time using non-contact instruments.

Environmental Chamber Condition Change Intervention

For condition change studies, the chamber will operate between 65 and 85 degrees F and 25% and 80% RH with air flow turned off or set to a maximum of 3-4 m/s. For this type of study, we will have the subject acclimate to a set of environmental conditions (approximately 20-30 minutes) and take a set of measurements. Then we will change the conditions (rate of change is 3 degrees F/hour and 3% RH/hour), have the subject acclimate to these conditions (later on the same day or on another day) and take another set of measurements. The expected study length is approximately two hours for a single visit. Subjects may be asked to return for additional visits to accommodate a variety of chamber conditions (temp, humidity, airflow) within the prescribed limits above.
