Purpose
Accurate measurement of the anterior segment parameters of the eye in cataract surgery is crucial for the calculation of intraocular lens (IOL) power using modern biometric formulas. This study aims to compare the anterior segment parameters obtained with Pentacam and ARGOS biometry devices.
Setting
This cross-sectional study included patients who underwent uncomplicated cataract surgery with toric (Alcon IQ SN6ATx) or EDOF (Extended Depht of Focus) toric (Alcon IQ Vivity® Toric) intraocular lens (IOL) implantation by the same surgeon (DDA) at the Department of Ophthalmology, Başkent University Hospital, between November 2023 and April 2024.
Methods
A total of 28 eyes from 15 female and 13 male patients were included in the study. Measurements with low reliability from preoperative Pentacam and ARGOS biometry were excluded from the study. For the analysis of dependent variables, paired t-test was used for normally distributed data, and the Wilcoxon test was applied for non-normally distributed data; Spearman’s correlation test was used for correlation analyses.
Results
Keratometry values (K1 and K2), astigmatism, axis, and anterior chamber depth (ACD) measurements from Pentacam and ARGOS devices were compared. No statistical difference was observed between pupil sizes during measurements (p=0.363). No statistical differences were found between the devices for K1, ACD, and axis values (p=0.799, p=0.698, and p=0.070, respectively). It was observed that K2 and astigmatism values measured with ARGOS were higher compared to Pentacam data (p=0.026 and p=0.01, respectively). The ARGOS biometry outputs showed a strong positive correlation between the postoperative expected astigmatism based on the selected IOL and the astigmatism values at the first postoperative month (r=0.725, p=0.02).
Conclusions
This study demonstrates that Pentacam and ARGOS devices provide similar results for anterior segment measurements, and the differences in keratometry values did not affect postoperative outcomes. Based on the ARGOS results, it is suggested that optimal outcomes can be achieved with toric IOLs.
