This confusion may be ascribed to the substitution of the fraction of adrenaline in the catecholamines extracted from the human adrenal medulla for the fraction of adrenaline cells in human AMC cells.

This literature review elaborates the effect of CRS on contrast sensitivity, refractive regression, and dry eye, as these components are related to the quality of vision. We conducted a literature review by searching on Google Scholar, PubMed, and Science Direct with relevant keywords. We found that each variety of CRS has its own effects regarding contrast sensitivity, refractive regression, and dry eye, both for immediate and long-term effects following the surgery. Factors in the work environment of pilots, such as hypobaric hypoxia, low humidity, and ergonomic factors also have an influence on those visual outcomes.
