Comparison Study Of Automated And Manual Keratometry Readings.

This research study seeks to explore the relationship between clinical readings attained from an automated keratometer and from a manual keratometer. With the advent and popularity of automated equipment, the question arises as to how the new technology's diagnostic data compares to that gained from the current, well-established methods. Little research has been conducted on this topic, though the information is valuable to the practice that provides contact lens services and is considering purchasing automated equipment. Methods: This study took place at the Michigan College of Optometry, comparing the Grand Seiko automated keratometer to the manual keratometer. A total of 40 eyes (n = 40) were used to gather data, with both forms of measurement acquired on the same day. Three separate readings were taken from both keratometers, for an average measurement from each. Results: The results Lmveiled a significant difference between the automated and manual keratometers, however, the clinical relevance of the actual variance was minor. Discussion: This study revealed that an experienced clinician could utilize measurements from either form of keratometer when compiling diagnostic data.
