Question: 1 / 400

What is the proper term for an astigmatic eye that has an anterior focal line in front of the retina and a posterior focal line behind it?

Simple astigmatism

Mixed astigmatism

The appropriate term for an astigmatic eye that exhibits an anterior focal line in front of the retina and a posterior focal line behind it is mixed astigmatism. This form of astigmatism indicates that one meridian of the eye is myopic (short-sighted), causing light to focus in front of the retina, while the other meridian is hyperopic (far-sighted), leading light to focus behind the retina.

This distinction of mixed astigmatism is critical because it encompasses a combination of both types of refractive error, which can result from variations in the curvature of the cornea or the lens. Understanding this concept is essential for accurate diagnosis and appropriate treatment planning, as it influences the type of corrective lenses or surgical options that would be most effective for a patient.
