The value and location of angles alpha (α) and kappa (κ) in the eyes diagnosed with hyperopia, qualified for premium class lens implantation were subject to evaluation. 67 patients, 101 eyes with hyperopia ranging from +0.5 Dsph to +10.62 Dsph were included into the study. For both angles, α and κ, their most common location is in the inferior temporal quadrant, followed by the superior temporal quadrant. A statistically significant correlation was observed between the value of angles α and κ and the range of hyperopia. In each case the angle value was examined using the iTraceTM analyser.
