In a prospective study we measured the intraocular pressure (IOP), the central corneal thickness (CCT) and the central corneal curvature in 172 myopic eyes before and after LASIK treatment. We find a significant decrease in intraocular pressure. Statistical evaluation reveals a linear correlation between the IOP decrease and the amount of stromal ablation. The IOP and corneal curvature are measured in 21 hyperopic eyes before and after LASIK treatment. We do not find a change in the IOP. In a retrospective study of 47 myopic eyes before and after RADIAL KERATOTOMY we find no change in IOP. We conclude that CCT is important in evaluating the IOP and that corneal curvature has little effect on IOP measurement.
