Dear Editor,

We thank the authors for their interest in our article [1] and appreciate their comments. We understand that performing correlations in each refractive group holds the numerals into a narrow interval, especially among myopes where the total number is only 50. However, in our study, the only moderate correlation that we have been able to demonstrate was in a small group of myopes between 35 and 39 years of age (n=16).

As suggested by the authors we performed Pearson's correlation coefficient and analysis of variance (ANOVA) on the 316 subjects to look for any possible correlation. The Pearson's correlation coefficient r between amplitude of accommodation (AA) and central anterior chamber depth (CACD), AA and lens thickness (LT), and AA and axial length (AL) was -0.041, -0.0906 and -0.0649 respectively. [2] ANOVA also did not show any significant correlation between AA and the ocular parameters. The significance level (P) for the correlation between AA vs. CACD was 0.192, AA vs. LT was 0.16 and AA vs. AL was 0.964.

Since myopes had the maximum correlation, there is a possibility that increased anterior chamber depth in these patients allows the lens to move forward during accommodation. A larger number of myopes would bring out the correlation if any between AA and ocular parameters.
