Webb20 juni 2024 · Autokeratometers, manual keratometry, and the simulated keratometry feature of most topographers estimate central corneal power by different methods. For this reason, we should never expect that these three different approaches will always produce the same value for the same eye.

WebbThe keratometry readings from the VERION reference unit were recorded but not used in the actual calculation. Vector differences between expected and actual residual refractive cylinder were calculated and compared to simulated vector errors using the collected VERION keratometry data.
