The study focused on understanding the corneal asphericity coefficient (Q value) among Saudi individuals to improve intraocular lens selection and correct spherical aberration during surgeries.
It analyzed 500 healthy participants aged 17 to 58, using a specialized camera to measure Q values across different corneal quadrants and surfaces, while considering factors like age, sex, and refractive error.
Results showed that the mean Q values were negative overall, indicating a prolate shape, with variations observed across quadrants and a significant trend of becoming less prolate as participants aged, but no notable differences between genders.
