The study showed that Corvis ST's bIOP and ORA's IOPcc do not agree well, before or after PRK, and may not be used interchangeably. bIOP remained unchanged after PRK. To evaluate the agreement between the biomechanically-corrected intraocular pressure (bIOP) measured by the Corvis-ST and the cornea-compensated IOP (IOPcc) measured by the Ocular Response Analyzer (ORA) before and after photorefractive keratectomy (PRK). In this prospective interventional study, a total of 53 patients (53 eyes) were included. Measurements were acquired using both the Corvis-ST and ORA devices before and 3 months post- PRK. The agreement between the two devices was evaluated using limits of agreement (LoA) and Bland-Altman plots. The participants had a mean age of 29.6±5.21 years (range: 21 to 40), with 41 (77.4%) of them being female. Following the surgery, the average change in IOP was 0.3±1.7mmHg for bIOP and -1.6±4.0mmHg for IOPcc. The corresponding 95% LoA were -3.5 to 4.2mmHg and -9.5 to 6.3mmHg, respectively. The 95% LoA between bIOP and IOPcc after PRK was -2.3 to 8.5mmHg. Notably, the bIOP values were higher for IOPs <20mmHg and lower for IOPs >20mmHg compared to IOPcc. The findings indicate a weak agreement between the Corvis ST-bIOP and the ORA- IOPcc both before and after PRK. These devices may not be used interchangeably for IOP measurement. bIOP exhibited less variation compared to the IOPcc, suggesting that the bIOP is a superior option for IOP reading following PRK.
