Sir,

We thank Dr. De Bernardo and Rosa for their interest in our study on the comparison of two topical steroids after myopic photorefractive keratectomy. As they mentioned, there are limitations associated with intraocular pressure (IOP) measurements after refractive surgery.[12] Therefore, no acceptable definition is available for steroid-induced ocular hypertension after refractive surgery, and various authors have employed different criteria to ascertain this. For instance, Busool et al classified patients as steroid responders if they had an IOP elevation of at least 25% while on topical steroid treatment (minimum of 28 mmHg) followed by an IOP drop of at least 25% when steroid treatment was discontinued.[3] In another study by Kimet al, ocular hypertension was defined as postoperative IOP increase of more than 30% compared to predicted IOP adjusted by corneal thickness.[4] We agree that considering only patients with an IOP increase >10 mmHg or IOP >21 mmHg (accepted definition for virgin eyes) eliminates some patients who are at risk. For this reason, we also considered an IOP increase of more than 5 mmHg as a significant change in our study. Using this criterion, three patients in our study were steroid responder.
