Comparison of Eyelid Heating Efficacy of Warm Compress Products Commercially Available in Korea

Abstract

Purpose: To compare eyelid heating efficacy according to the type and the method of use of eyelid warm compress products commercially available in South Korea. Methods: For six healthy adults, three types of eyelid warm compresses were worn for 10 minutes and the temperature of the product surface, external upper lid, external lower lid, and internal lower lid were measured every 2 minutes. The average of the measured values was divided into four groups according to the type of product (Moist Heat Eye Compress (R), Megrythm Steam Eye Mask (R), Nurieye-5900 (R)-High Temperature Mode [H], Nurieye-5900 (R)-Low Temperature Mode [L]) and were compared. Results: Eyelid temperature showed a significant difference between each group after the first 2 minutes of treatment (p < 0.000). In the Moist Heat Eye Compress (R) group, the temperature of the external upper lid was maintained above 38 degrees C until 6 minutes and the remaining groups did not exceed 38 degrees C. The temperature of the inner lower lid was maintained at 37 degrees C or higher for 10 minutes in the Moist Heat Eye Compress (R) use group and exceeded 37 degrees C at 6 minutes in the Megrythm Steam Eye Mask (R) use group. The remaining groups did not exceed 37 degrees C. Conclusions: For the external eyelid, only the Moist Heat Eye Compress (R) group were heated above 38 degrees C. For the inner lower lid, Moist Heat Eye Compress (R) and Megrythm Steam Eye Mask (R) groups were heated above 37 degrees C, showing a higher heating effect. Further studies are required on the effects of the three warm compress products in patients with Meibomian gland dysfunction.
