NAISMITHA Pilot Study on the Use of a Sensory Panel to Assess Comfort Between Three Different Contact Lenses

As technology continues to advance, contact lenses and lens care products are becoming harder to differentiate. In addition, assessing comfort in clinical trials is complicated, with full-masking behind hard to achieve and the psychology of the participant having unknown impact on the results. While the development of a reliable system to assess comfort would be beneficial for the research and development of new products, the use of a "sensory panel" itself may also lead to a better understanding of the drivers of discomfort at the end of the day. The objective of the study is to explore the use of a sensory panel, defined as individuals who have a good correlation between subjective and objective measures of discomfort, at rating the comfort of various contact lenses. The hypothesis is that in the "discriminative" group, the matrix of paired comparisons (between lens dissimilarity) is related to the ranked comfort of the lenses, while for the "poorly discriminative" group, the matrix of the dissimilarities will be random. An additional hypothesis is that the "discriminative" group will be less random than the entire group.
