| description | Objectives: To research the repeatability and intercompatibility of keratometry values measured with Potec PRK-6000
autorefractometer, IOL Master, and Pentacam.
Materials and Methods: In this prospective study, consecutive measurements were performed in two different sessions with the
mentioned three devices on 110 eyes of 55 subjects who had no additional ocular pathology except for refraction error. The consistency
of flat and steep keratometry, average keratometry, and corneal astigmatism values obtained in both sessions was compared by using
intraclass correlation coefficient (ICC). The measurement differences between the devices were statistically compared as well.
Results: The mean age of the study subjects was 23.05±3.01 (18-30) years. ICC values of average keratometry measurements obtained
in the sessions were 0.996 for Potec PRK-6000 autorefractometer, 0.997 for IOL Master, and 0.999 for Pentacam. There was high
compatibility between the three devices in terms of average keratometry values in Bland-Altman analysis. However, there were
statistically significant differences between the devices in terms of parameters other than corneal astigmatism.
Conclusion: The repeatability of the three devices was found considerably high in keratometry measurements. However, it is not
appropriate for these devices to be substituted for each other in keratometry measurements. (Turk J Ophthalmol 2014; 44: 179-83) |
