ABSTRACT

This study was carried out to compare the amplitude of accommodation and binocular cross cylinder methods in determination of reading Add. A total of sixty two (62) presbyopic subjects where used and thirty were males and thirty were females. Amplitude of accommodation and binocular cross cylinder test were performed and the reading add were determined using amplitude of accommodation and binocular cross cylinder methods. The mean add determined through the amplitude of accommodation were 1.39 ± 0.57 and the mean add determined through the binocular cross cylinder were 1.89 ± 0.59. statistically software using pared sample T-test at 0.05 level of confidence and 95% confidence interval showed that there was a significantdifference (P<0.05) in obtaining the reading add using the amplitude of accommodation and binocular cross cylinder method. Reading add determined through binocular cross cylinder method provides a tentative reading add closer to the final reading add than the reading add determined through the amplitude of accommodation method. Binocular cross cylinder method should be used when determining reading Addition for presbyopes since it gives a tentative reading Addition closer to the final reading Addition for presbyopic subjects.
