Analysis of biometric data generated by interferometry compared with Scheimpflug

DOI: 10.5935/0034-7280.20200062

Abstract

Objective:

Observe the agreement between IOL Master 500 and Pentacam AXL and describe the averages.

Methods:

We analyzed 35 medical records, totaling 61 eyes. All patients underwent biometric evaluation on both devices from August 2018 to August 2019. The data collected were: age, gender, anterior chamber depth, axial length, K1, K2, biometrics and IOL target.

Results:

The averages of the variables analyzed between the optical biometric devices in question had a statistically significant difference (p <0.05). Linear regression showed no influence of any anterior chamber variables on the difference in biometrics and target values between the devices.

Conclusion:

There was no statistical agreement between the devices for the analyzed variables. Therefore, the interchange of Pentacam AXL with IOL Master 500 should be avoided.
