To confirm your diagnosis and begin planning your astigmatism treatment in Los Angeles, Dr. Benjamin and his team will perform a series of tests. First, you can expect a standard vision examination, during which you will read the letters on an eye chart. You will then look through a phoropter (a large machine with lenses of varying strengths) so Dr. Benjamin can determine your prescription.
From there, Dr. Benjamin will measure the bend of your cornea and how well you can focus using a Pentacam corneal topography. He will then utilize corneal topography technology to collect thousands of tiny measurements as your eye focuses. A computer will use those measurements to build a color map of your cornea, which will guide surgery if Dr. Benjamin determines it’s necessary for your astigmatism treatment.
