You may have noticed that you have the signs of astigmatism and have also decided to visit an ophthalmologist. What can you expect?
Firstly, expect the typical visual acuity test where they ask you to look at numbers, letters, and images at certain distances. Afterward, the doctor might ask you to undergo several more tests and use a few other instruments, which might include a:
- Keratometer to determine the shape (curvature) of your cornea
- Corneal topography, which makes a contour map of the cornea — useful for contact lenses
- Phoropter, which uses a series of lenses to check which provides the clearest vision
With these tests, the doctor can “measure” your astigmatism and prescribe corrective eyeglasses or contact lenses. Of course, surgery, such as LASIK, can also be recommended.
