Abstract Details

Purpose:

To evaluate the rate on measurement acquisition success and correlations between biometric parameters using three different biometers in patients with mature cataract.

Setting:

Research Department, Oftalmosalud Institute of Eyes, Av. Javier Prado Este 1142, San Isidro, Lima 27, Perú

Methods:

Prospective, comparative study that included 45 eyes with mature cataract that attend to Instituto Oftalmosalud, Peru, between September 2018 to January 2019. Three consecutive scans were acquired with each device: Pentacam AXL (Oculus, Wetzlar, Germany), Galilei G6 (Ziemer, Port, Switserland) and IOL Master 700 (Carl Zeiss Meditec AG, Jena, Germany). Were obtained the following variables: Axial Length (AL), Anterior Flat (AFK) and Steep Keratometry (ASK), Anterior Astigmatism, Mean K, Anterior Chamber Depth (ACD), Central Corneal Thickness (CCT) and Lens Thickness (LT). Coefficient of Concordance and Correlation (CCC) was used for correlation. Quade test was used for comparisons between devices.

Results:

After 3 measurements, Pentacam AXL (P), Galilei G6 (G) and IOL Master 700 (IOL) could measure axial length in eyes with mature cataract in 17 eyes (37.7%), 19 eyes (42.2%), and 38 eyes (84.4%) respectively.  Was statistically significant in AFK [42.63 ±2.13, 42.92 ±2.10, 42.76 ±2.06 on Pentacam, Galilei and IOL Master] (p=0.027) Mean K [43.23 ±2.04, 43.58 ±2.09, 43.41 ±2.02] (p=0.008) and CCT [542.63 ±33.05, 535.91 ±34.80, 533.38 ±37.32] (p=<0.001). Significant differences were found in the AFK between PvsG (p=0.042), in Mean K between PvsG (p=0.010) and GvsIOL (p=0.034), and in CCT between PvsG (p=0.002) and PvsIOL (P=<0.001).

Conclusions:

The IOL master 700 had the highest AL acquisition success rate when compared with the Pentacam AXL, Galilei G6. AL, ACD, and average Ks had significant differences between devices.
