From: Corneal functional optical zone under monocular and binocular assessment
Correlation between the estimated binocular Function Optical Zone (FOZ) to the estimated monocular FOZ and the Intercorneal difference in terms of FOZ. The estimated binocular FOZ was larger than monocular FOZ, but both strongly positively correlated (even/direct symmetry). The estimated binocular FOZ was smaller than the intercorneal differences, but both strongly positively correlated (even/direct symmetry). This confirms good symmetry in corneal aberrations for our study population
