Corneal topography is a diagnostic procedure used to measure the curvature of the cornea. It is used to diagnose and monitor a variety of eye conditions, such as astigmatism, keratoconus, and corneal scars. It is also used to evaluate the effectiveness of certain treatments, such as laser eye surgery.
Who needs corneal topography?
Corneal topography is typically recommended for people who have vision problems that cannot be corrected with glasses or contact lenses. It is also used to monitor the progression of certain eye conditions, such as keratoconus.
Who performs this procedure?
Corneal topography is typically performed by an ophthalmologist or optometrist.
How do I prepare?
You should not wear contact lenses for at least 24 hours before the test. You should also remove any eye makeup before the test.
How is corneal topography done?
During the procedure, a special camera is used to take pictures of the front surface of your eye. The camera takes multiple images from different angles, which are then used to create a detailed map of the cornea.
What can I expect after the test?
After the test, you may experience some mild discomfort, such as a burning sensation or light sensitivity. These symptoms should resolve within a few hours.
What are the risks of this test?
Corneal topography is a safe procedure with minimal risks. The most common risk is a temporary increase in light sensitivity.
What do the results mean?
The results of the test will be used to diagnose or monitor certain eye conditions. Your doctor will explain the results to you in detail.
When should I call my doctor?
You should call your doctor if you experience any persistent discomfort or vision changes after the test.
