Diagnosis of Astigmatism
An eye specialist known as an optometrist or ophthalmologist is who diagnoses astigmatism, using a comprehensive eye exam.
- An optometrist is an eye doctor that diagnoses vision problems and eye diseases.
- An ophthalmologist is a doctor who provides medical and surgical treatment of vision problems and eye diseases.
There are several tests optometrists and ophthalmologists may use during eye examination to diagnose astigmatism.
Visual acuity test
Your doctor will conduct a visual acuity assessment test on you during which you will be asked to read letters from a chart at a particular distance in order to gauge your visual acuity.
Keratometry
Your doctor will use keratometry to gauge the cornea’s curvature. By using a keratometer to examine your eye, they will be able to achieve this.
The refractive test
A device known as an optical refractor is used in refraction testing. The device is equipped with several corrective lenses of various strengths. Your doctor will want you to use the optical refractor to view a chart while using lenses of various strengths. It won’t take them long to locate a lens that can properly correct your vision.
