Anterior corneal asphericity calculated by the tangential radius of curvature [PDF]
Journal of Biomedical Optics, 2012 We propose a method of calculating the corneal asphericity (Q) and analyze the characteristics of the anterior corneal shape using the tangential radius. Fifty-eight right eyes of 58 subjects were evaluated using the Orbscan II corneal topographer. The Q-values of the flat principal semi-meridians calculated by the sagittal radius were compared to ...

Correlation between changes in corneal asphericity and progression of keratoconus in children
Journal of the Egyptian Ophthalmological Society, 2022 Clinical relevance Early detection of keratoconus (KC) progression and timing for retreatment. Background Q value (coefficient of corneal asphericity) reflects the shape of the cornea, its refractive power, and spherical aberration.
