AIM: To investigate the possible impact of conductive keratoplasty (CK) on intraocular pressure (IOP). METHODS: 36 eyes of 20 patients with hyperopia underwent IOP measurement with non-contact tonometer (NCT), Goldmann applanation tonometer (GAT) and Schiotz tonometer before and after CK. RESULTS: After CK, a significant decrease was observed by NCT, GAT and Schiotz measurements. The change in IOP readings was not correlated with age, sex, keratometric readings, or attempted correction. CONCLUSION: The applanation tonometer tends to underestimate the true IOP after CK.
