Purpose
To compare measurement agreement between two new anterior segment swept-source optical coherence tomography (SS-OCT) devices combining tomography and biometry (ANTERION, Heidelberg Engineering, Heidelberg, Germany, and EYESTAR 900, Haag-Streit Diagnostics, Miami, FL), and a combined optical/SS-OCT biometer (TOMEY OA-2000, Tomey, Nagoya, Japan).
Setting
Tel Aviv Medical Center, Tel Aviv, Israel (tertiary care center)
Methods
A retrospective study including subjects who underwent evaluation and biometric measurements prior to cataract surgery using the three devices (ANTERION, EYESTAR 900, TOMEY OA-2000). Measurements of axial length (AL), anterior and posterior keratometry, anterior chamber depth (ACD), corneal diameter (WTW), central corneal thickness (CCT) and lens thickness (LT) from all devices were recorded. Analysis of measurement agreement and correlation was performed. Intraocular lens (IOL) power calculations were performed based on each device’s measurements and compared.
Results
In 82 eyes of 46 patients included in the study, mean AL, keratometry and WTW were statistically but not clinically different between the devices. Mean CCT, ACD and LT were both statistically and clinically different.
Correlation and agreement between EYESTAR and ANTERION were good for all variables. Reduced correlation and agreement were found between the TOMEY and either EYESTAR or ANTERION in ACD, WTW and LT measurements. This was also the case for AL measurements in cases where TOMEY signal-to-noise ratio (SNR) was below 10.
Agreement in IOL calculation was good between EYESTAR and ANTERION and reduced between the TOMEY and either EYESTAR or ANTERION, especially in cases where TOMEY SNR was below 10.
Conclusions
The EYESTAR and ANTERION had good agreement and correlation and can be used interchangeably for IOL power calculations. Agreement and correlation between TOMEY and either EYESTAR or ANTERION were reduced, especially in cases where TOMEY signal-to-noise ratio was low.
