| Summary: | Background: Researchers have found that the refractive states of the eye are influenced by a variety of variables.
Aim: This study investigated the correlation between the central corneal power (CCP) and a number of variables, which include axial length (AL), anterior chamber depth (ACD) and the central corneal thickness (CCT) in near-emmetropic eyes of students.
Setting: The study was conducted in the Optometry Laboratory of the Islamic University-Gaza (IUG), Palestine.
Methods: In a prospective analysis, 200 near-emmetropic students were examined from February 2019 to May 2019 with an ultrasound scanner (A-scan), ultrasonic pachymeter and Visionix L79 automated refractometer Keratometer (ARK). Only the data of one eye were randomly chosen for investigation.
Results: The means and standard deviations (s.d.) of the CCP, AL, ACD and CCT for male students (n = 97) were 43.19 dioptre (D) ± 1.34 D, 23.54 mm ± 0.68 mm, 3.59 mm ± 0.26 mm and 549 µm ± 33 µm, respectively. Furthermore, the means ± s.d. of 103 female students were as follows: CCP 43.85 D ± 1.43 D, AL 22.94 mm ± 0.69 mm, ACD 3.35 mm ± 0.25 mm and CCT 543 µm ± 35 µm. There was a significant association between CCP and gender (p = 0.00). There was a negative significant correlation between CCP and AL for both the male (r = −0.64; p = 0.00) and the female (r = −0.71, p = 0.00) participants.
Conclusion: This study provided information on CCP, AL, ACD and CCT in near-emmetropic eyes of adults. In male students, CCP was flatter and AL was longer when compared with female Palestinian students. |
