In this letter, we reply to the issues presented by Dr Ali Poostchi and associates in their correspondence to the Editor regarding our article.

We thank Dr Poostchi and his associates for sharing their findings on the associations between the corneal hysteresis and intraocular pressure. We are in agreement with their explanations that the associations may be related to the measurement of the ocular response analyzer (ORA), which was not considered in our article. We hope this exchange will stimulate further research.
