Характеристики и точность прогнозирования в зависимости от жесткости роговицы при подозрении на кератоконус.

The refractive power of the cornea is approximately +43.05 D, which accounts for two-thirds of the total refractive power of the human eye, and therefore plays a crucial role in vision. The stromal layer of the cornea comprises approximately 90% of its thickness, and it is known that the regular arrangement of collagen fibers is essential for maintaining corneal transparency. Stiffness refers to the degree to which a material resists deformation when an external force is applied. In the cornea, this mechanical property is primarily influenced by the density and thickness of its collagen fibers [¹].
