Analysis of the AC/A ratio in myopia patients in relation to spectacles and soft contact lenses

Purpose: To compare accommodative convergence over accommodation (AC/A) ratio when Myopic patient changes from Spectacles to Contact lenses.Methods: A prospective, cross-sectional study group of 50 subjects and error -0.75DS - 6.00DS. The AC/A was measured by two methods; the heterophoria method gradient method. Gradient plus minus Lenses technique. Heterophoria in near distance calculate Wilcoxon Signed Ranks Test used between methods p value < 0.05.Results: mean using Soft comparison was: with+3(2.21, 2.24), with-3(1.51,150) respectively. Although less amount with +3D lens more -3D as compared Spectacles, there were no significant differences found (P:0.285 P:0.317 respectively). means calculated increased soft contact lenses (5.97) spectacles (5.96) difference p: 0.317Conclusion: No has been for myope changing
