Objective:

Compare biometric measurements taken with IOL Master 500 and Pentacam AXL.

Methods:

A cross-sectional study was conducted of 99 eyes of 99 myopic patients with indication of photoablative surgery attending the Refractive Surgery Service at Ramón Pando Ferrer Cuban Institute of Ophthalmology from January 2019 to January 2020. The variables analyzed were age, sex, spherical equivalent and preoperative biometric characteristics (axial length, anterior chamber depth and keratometries) and the relationship to one another, automatically supplied by IOL Master 500 and Pentacam AXL to avoid operator-dependent factors. Statistical analysis was based on the paired T-test with a significance level of 95%. A difference with a p-value < 0.05 was considered to be statistically significant.

Results:

Of the patients studied, 60.61% were female and 39.39% were male; mean age was 25.67± 4.30 years. A total 51 right eyes and 48 left eyes were analyzed. Mean spherical equivalent was -3.30 ± 1.53 diopters. No statistically significant difference was found between the biometric values (axial length, anterior chamber depth and keratometries) obtained with IOL Master 500 versus Pentacam AXL (p> 0.05).

Conclusion:

Similar biometric measurements (axial length, anterior chamber depth and keratometries) are obtained with IOL Master 500 and Pentacam AXL.
