NEW PERMANENT HUMIDITY COMPARTMENT FOR LU BRICATION DISORDERS

Background In corneal lubrication or eyelid closure disorders it may b e necessary to apply a monoculus to protect the eye from drying out. C hanging the monoculus involves dermal irritation. Furthermore, because the monoculus is not completely airtight, the desired humidity is not achieved. Instrument We introduce a tape-free permanent humidity cham ber fastened to a spectacle frame that achieves a relative humidity of more than 98% even over a long period of time. Patients/Tested Person s Five test persons and two patients with lagophthalmus were treated w ith a monoculus and with the permanent humidity chamber. Comparative m easurements of the humidity achieved with the two methods were done. R esults For both test persons and lagophthalmus patients the permanent humidity chamber is a good alternative to the monoculus, because it ma intains a humidity of more than 98% r/H over a period of eight hours o r longer. It consequently provides much better conditions for successf ul treatment and additionally minimizes skin irritation.
