Hypothesis
To evaluate the ocular biometry agreement and prediction of postoperative refractive outcomes obtained using two swept-source optical coherence tomography (SS-OCT) biometers: Anterion and Argos.
Conclusion
The Anterion and Argos devices showed minor differences in ocular measurements, with Anterion tending towards slightly more myopic refractive errors.
Supporting Evidence
- Anterion showed statistically significantly greater axial length, central corneal thickness, and lens thickness than Argos.
- There were no significant differences in measuring anterior chamber depth.
- Anterion showed flatter corneal curvature measurements than Argos.
- The postoperative prediction errors differed for all three formulas.
Takeaway
This study looked at two devices that measure the eye before cataract surgery and found that one device gave slightly different results than the other, but both were good at predicting how well patients would see after surgery.
Methodology
Ambispective analysis of 105 eyes, comparing biometric values using Anterion and Argos before cataract surgery.
Limitations
The study had a relatively small sample size and a retrospective design.
Participant Demographics
Mean age 71.43 years, 55.2% female.
