Abstract
Background: The cornea measures eleven to twelve millimeters in diameter horizontally and ten to eleven millimeters in vertically. It is a clear, avascular tissue. This substance has a refractive index of 1.376. Despite the cornea's aspheric shape, its radius of curvature is typically expressed as a spherical convex mirror that depicts the corneal cap or central anterior corneal surface.
Aim and objectives: To select which age group cornea is more suitable for corneal transplantation and will give a better prognosis.
Patients and methodology: This was a across-sectional non-interventional comparative investigation performed at Al-Hussien University and Bab Al-Shaarea Hospitals from the beginning of January 2021 to the end of December 2024. This study included 300 eyes which were divided into six groups.
Results: The central corneal thickness (CCT) increases with age to reach the highest value between 40 and 49 years and then started to decrease beginning from 50 years onward. Group two and group three exhibited a statistically important rise in the coefficient of variation (CV) in size compared to group 1. However, the CV of size started to decrease again starting from 40 years onward.
Conclusion: Increasing age is associated with corneal changes as detected by specular microscope including decrease endothelial cell density, decrease the specular percentage of hexagonality and increase average cell size.
