Reliability of the IOLMaster in Measuring Corneal Power Changes After Hyperopic Photorefractive Keratectomy

Methods: Two hundred twenty-five consecutive eyes that had PRK (mean 5.13 diopters [D] 2.98 [SD] [range 0.25 to 16.25 D]) were analyzed. The data included preoperative and postoperative (1, 3, and 6 months) subjective refraction and computerized keratometry. Statistical analysis was performed to determine the correlation between the changes in the subjective refraction at the corneal plane and the changes in keratometry.
