Astigmatism: Symptoms, Diagnosis and Treatments
Patients with astigmatism have blurred vision at all distances. Often, a patient with astigmatism can have another eye disorder, such as hyperopia (farsightedness) and myopia (nearsightedness).
Besides blurred vision, patients can also experience headaches, squinting, eye strain and discomfort, and fatigue. The National Eye Institute added that patients with astigmatism can have difficulty driving at night.
To diagnose astigmatism, the doctor will measure the light reflected from the cornea and measure the curvature of the cornea. To measure reflected light, the doctor will use a keratometer, which also measures the orientation of the astigmatism. A keratoscope is used to measure the curvature and allows the doctor to see the degree of the curvature.
Several treatment options are available for astigmatism. If a patient’s astigmatism is minor and she does not have hyperopia or myopia, the University of Michigan Kellogg Eye Center noted that she may not need corrective lenses.
