Cohort Study: Corneal Higher-Order Aberrations and Its Related Factors in Chinese People with Emmetropia

Abstract

HOAs, such as the distribution in the population and changes with increasing aging, are essential for understanding the nature of each aberration and correcting it. Hence, the purpose of this study were: firstly, to obtain information about characters of anterior and posterior corneal HOAs in the Asian eyes of Chinese people with emmetropia and to compare them with findings in other series in the literature; secondly, to determine their relationships with age, gender, CCT and ACD. Materials and Methods This study was designed as a prospective, randomized study and followed the tenets of the Declaration of Helsinki. Informed consent was obtained from each candidate. A total of 1026 eyes of 1206 candidates, 605 male (50.2%), 601 female (49.8%) were examined, only right eyes were considered. Corneal HOAs were computed from the central 6.0 mm zone of the corneal topographic maps. All Subjects came spontaneously for consultation and were subdivided into six age groups. The subjects were submitted
