Purpose: To compare the preoperative and postoperative values of IOP in a group of patients after photorefractive keratectomy (PRK) and to evaluate the sensitivy to steroid drops. Methods:One hundred and twenty-two patients who un-derwent PRK from February 1994 to December 1996 were analized retrospectively. IOP measurements were taken with a Goldmann applanation tonometer preoperatively and postoperatively on the 30th, 60th and 180th day. All of them received the same postoperative routine, including steroid drops.Results: Comparing with the preoperative values, there was a statistically significant increase in IOP on the 30th postoperative day, while there was a statistically significant decrease in IOP at the 6th month.Conclusions: On the 30th postoperative day, IOP showed a statistically significant increase probably due to the use of steroid drops. Six months IOP showed a statistically significant decrease in relation to preoperative values.
