Purpose: To identify the correlation between angle kappa, corneal high order aberrations and total eye aberrations in myopic, hyperopic and astigmatic patients. Methods: An analytical cross-sectional study was conducted among 206 eyes of 103 patients with errors of refractions in the department of ophthalmology, Sohag university hospital in the period from March 2023 to September 2023. The studied cases were divided into 3 groups: Group (1) included 68 myopic eyes. Group (2) included 44 hypermytropia eyes. Group (3) included 94 astigmatic eyes. A comprehensive evaluation of refraction was conducted on all patients with an autokerato-refractometer. Following this, a series of topographic imaging procedures were conducted on all patients in order to get measurements of angle kappa and high order aberration of the cornea. In addition, higher-order aberrations of the total eye were recorded. Results: The study was conducted among 206 ame-tropic eyes of 103 participants. It was found that there was statistically significant difference between the studied groups according to visual acuity and angle Kappa. Also, there is statistically significant difference between the studied ametropia groups according to Coma and trefoil abe-rration of cornea and total eye while there is statistically insignificant difference between the groups regarding spherical aberration either of cornea or total eye. Assessment of correlation between corneal high order aberrations showed that there is significant moderate positive correlation between angle Kappa and Spherical aberration of cornea among astigmatism group. On the other hand, there is insignificant correlation between angle Kappa and HOAs of total eye among different ametropia groups. Conclusion: There was statistical significance between spherical aberrations of the cornea and angle kappa in the astigmatic group only. Also, there was a statistical significance between the UCVA and Angle kappa in cases of astigmatic groups which are consistent with each other and denote consideration of angle kappa measurements preop-eratively especially in cases of astigmatic patients.
