Ultrasound with Lens Calculation - Eye

This test uses sound waves to measure the length of the eye from front to back to determine the strength of a lens implant.




This test uses sound waves to measure the length of the eye from front to back to determine the strength of a lens implant.



An ultrasound of the eye, also called echography, uses sound waves to create images and measurements of the structures in the eye(s).

  • This test only includes one-dimensional images (A-scan).
  • During an A-scan, you will look straight ahead.

Your healthcare provider, usually an ophthalmologist or optometrist, may order this test to:

  • Measure the length of the eye from front to back
  • Determine the strength of a lens implant during surgery for cataract removal

An ultrasound of the eye takes about 15 minutes and is usually painless.

  • Prior to the test, your healthcare provider will numb your eye with special drops.
  • He or she will then place a special probe covered with a clear gel on the front of your eye.
  • The probe does not come into direct contact with your eye.
  • The gel will help send the sound waves to the computer.

Your healthcare provider will tell you if you need to do anything to prepare for the ultrasound.

The costs for this test include the charge for the test (facility charge) and physician charges (for performing or interpreting the test). You may get separate bills from the facility and the physician's office.

What should I ask my healthcare provider before having this test?

  • Is there any special preparation for the test? (If so, get clear instructions on what you need to do.)
  • Why are you ordering this test? Will the test results change my treatment plan? If not, do I need the test?
