Patients experiencing symptoms of an astigmatism should consult with an eye doctor, especially when a lessened quality of vision interferes with their ability to complete daily routines, tasks or activities, warns the Mayo Clinic. Routine eye exams every two to four years until the age of 55 are recommended to detect conditions that deteriorate vision. People 55 and older should have their eyes examined every one to three years, people age 65 and older should have their eyes examined and every one to two years.
As of 2015, the exact cause of an astigmatism is unknown, yet it is commonly associated with abnormalities within the shape of the cornea, according to WebMD. An astigmatism is treated with corrective lenses or contacts or refractive surgery. Refractive surgery, also known as laser eye surgery, changes the shape of the cornea surgically. Several types of refractive surgery exist, and they are specifically recommended based on the severity of an astigmatism. Patients with corneal scars, an eye disease or retinal problems are not typically eligible for refractive surgery.Learn more about Vision
