Purpose

To compare biometry of eyes obtained with two swept-source optical coherence tomography-based biometers: Argos (A) (Movu Inc., Komaki, Japan) and IOLMaster 700 (IM) (Carl Zeiss Meditec, Jena, Germany).

Setting

Department of Ophthalmology, Faculty of Medical Sciences in Katowice, Medical University of Silesia, Katowice, Poland

Department of Ophthalmology, Professor K. Gibinski University Clinical Center, Medical University of Silesia. Katowice, Polandk

Methods

Biometry of 105 eyes of 105 patients before cataract surgery with implantation of intraocular lens were analyzed in this study. Following parameters such as axial length (AL), anterior chamber depth (ACD), lens thickness (LT) from both devices were compared. According to the axial length measurements patients were divided into three groups: group 1 – short eyes (AL <22.5mm), group 2 – average eyes (AL ≥ 26.0 mm) and group 3 – long eyes (22.5 ≤ AL ≤ 26.0 mm). Data were analyzed using Statistica 13.3 software, StatSoft

Results

Statistical significance in axial length was indicated in group of short eyes (n = 26) - mean AL (A) 21,90mm (± 0,59mm) vs AL (IM) 21,8mm ± (0,61mm) (p< 0,001) and in group of long eyes (n = 5) - mean AL (A) 27,95mm (± 2,62mm) vs mean AL (IM) 28,10mm (± 2,64) (p<0,05).
In group of average eyes (n = 74) outcomes were similar - mean AL (A) 23,56mm (± 0,70mm) vs mean AL (IM) 23,56mm (± 0,71mm) (p> 0,05). Anterior chamber depth measurements were higher obtained with Argos than with IOLMaster 700 - mean ACD (A) 3,06mm (±0,48mm) vs mean ACD (IM) 2,92mm (±0,46) p< 0,001
There was no statistical significance in mean LT: mean LT (A) 4,75mm (±0,46mm) vs mean LT (IM) 4,72mm (±0,44mm) (p= 0,054).
Biometry of one eye with dense cataract could be measured only with Argos using Enhanced Retinal Visualization mode

Conclusion

Axial length measurements with both devices were different in groups of short and long eyes, but comparable in group of average eyes. Anterior chamber depth values obtained with Argos were higher than measurements acquired with IOLMaster 700. Lens thickness measurements were similar with both devices. Eyes with dense cataract could be measured with higher accuracy with Argos than with IOL-Master 700
