What does the "Shape Factor" on corneal topography printouts represent?

Variation of light reflection
Eccentricity of the cornea along the flatter meridian
Overall diameter of the cornea
Indentation of the cornea

The correct answer is: Eccentricity of the cornea along the flatter meridian

The "Shape Factor" in corneal topography printouts specifically refers to the eccentricity of the cornea along the flatter meridian. This measure indicates how much the shape of the cornea deviates from a perfect sphere. A higher eccentricity value typically suggests a more conical surface, which is often associated with conditions like keratoconus, whereas a lower value indicates a more spherical cornea. Understanding the Shape Factor is crucial for diagnosing and managing various refractive and corneal conditions. By assessing the eccentricity, practitioners can better understand the corneal curvature and its implications for vision correction procedures and overall eye health.
