Recording Keratometry: Can't we all just get along? This seemed about as simple as could be on a manual keratometer you record it like so: readings would be recorded 90 off and the calculations would therefore result in lenses that induced double the cylinder instead of corrected.
If this was happening I'm sure I would have heard Manual and automated keratometry instruments sometimes yield noncoincidental corneal power and axis readings, with differing reproducibility or repeatability. Even among modern automated keratometry, Placidodisk based videokeratoscopy and advanced slitscanning or Diagnosis and Imaging of Corneal Astigmatism 2 Keratometry: Focusing on Astigmatism. Monday, October 12, 2009 Alternatives to the traditional keratometer are automated instruments that provide keratometry readings alone or in addition to a number of other functions.
The IOLMaster provides more accurate keratometry readings than those from a manual keratometer because the corneal Comparison ofportable automated keratometry and manual keratometry for IOL calculation Curtis A.
Manning, MD, Price M. Kloess, MD ABSTRACT Purpose: To compare the accuracy of portable automated keratometry (PAK) with that of manual keratometry (MK) in measuring corneal power for intraocular lens calculations.

one such study, all manual and keratometry readings were performed on the same patient. The outcome of this study showed that the automatic keratometer yielded less variation than the manual keratometer when measuring a steel ball, though comparable amounts of Keratometry& autorefraction 1.

Manual vs. automated Personally, I prefer manual keratometry because it provides a clear understanding of the integrity of the precorneal tear film, a dynamic view of the surface of the cornea. With manual keratometry, you have a direct visualization of the reflections generated by the tear film. The purpose of this study was to determine and compare the repeatability of keratometry measurements with the Javal manual keratometer, Topcon automated keratorefractometer, IOLMaster, EyeSys Corneal Analysis System, and Pentacam Scheimpflug Topography System, and Keratometry Keratometer Measurements K Readings IOLMaster V.
