Purpose
Aim of this study is to determine the agreement and repeatability of different refraction methods in patients implanted with an enhanced monofocal intraocular lens (IOL) and compare the results with a known monofocal IOL.
Setting
Vienna Institute for Research in Ocular Surgery (VIROS), Hanusch Hospital, Vienna, Austria
Methods
This prospective study included patients implanted with an enhanced monofocal IOL (Eyhance, ICB00, Johnson & Johnson) in one eye and a monofocal IOL (ZCB00, Johnson&Johnson), as the control lens, in the fellow eye. Autorefraction measurements were performed with 4 different autorefractometers: Nidek Autorefractor ARK-1s (AR1), Topcon KR 800 (AR2), VisuRef 150, Carl Zeiss, Meditec AG (AR3), and Tomey Autorefractometer RC-5000, Tomey GmbH (AR4). Each patient was measured three times with each device. Two independent examiners performed subjective refractions and were masked to the autorefraction outcomes.
Results
Thirty patients completed the study. Mean spherical equivalent (M) for the study eyes (ICB00) was -0.26 ± 0.62 for AR1, -0.25 ± 0.57 for AR2, 0.09 ± 0.55 for AR3 and -0.17 ± 0.60 for AR4. The mean spherical equivalent for the control eyes was -0.28 ± 0.68 for AR1, -0.24 ± 0.63 for AR2, 0.04 ± 0.59 for AR3, and -0.32 ± 0.66 for AR4. The within-subject standard deviation (Sw) for the spherical equivalent for ICB00 was 0.26 for AR1, 0.10 for AR2, 0.05 for AR3 and 0.43 for AR4, respectively. The values for ZCB00 were 0.16, 0.09, 0.18 and 0.04 respectively
Conclusions
The differences between the autorefractometers and subjective refraction were small
