Twelve orthokeratology patients were studied to determine whether myopic orthokeratology treatments had an effect on intraocular pressure. It was our hypothesis that myopic orthokeratology would have no significant effect on intraocular pressure. The patients were fit in the OK-3 design lens and re-evaluated each week for changes in intraocular pressure using a Goldmann applanation tonometer. The results of this study indicated that the null hypothesis was accepted. Although it was indicated that there was a statistically significant difference between pre- and post-treatment lOP measurements, we feel that this variation is well within the normal range for Goldmann applanation. The literature suggests that the following factors can cause variation in Goldmann lOP measurements: measurement technique, physiological and anatomical status of the eye and diurnal variation.
