Purpose: To study the relationship between central corneal thickness (CCT) and intraocular pressure (IOP) response to phacoemulsification with clear corneal sutureless incision. Methods: In this prospective study, 100 eyes underwent measurements of CCT and IOP one week before surgery and the measurements were repeated at 1st and 6th postoperative months. CCT was measured with an ultrasonic pachymeter, and IOP was measured by Goldmann applanation tonometry. Results: The mean CCT was 551.17±31.84µm preoperatively and increased to 561.48±34.77µm and 560.85±34.15µm at 1st and 6th postoperative months respectively (p<0.001 for both comparisons). The mean IOP was 16.8 ±2.5mmHg preoperatively and the mean IOP decreased to 14.75±2.1mmHg one month after the surgery (p<0.001). At the 6th postoperative month, mean IOP decreased further to 14.2±1.9mmHg (p<0.001). The mean CCT increase was 1.81% and 1.78%, while the mean IOP decrease was 12.2% and 15.5% (1st and 6th months respectively). There was no statistically significant correlation between CCT increase and IOP decrease. Conclusions: IOP changes after clear corneal phacoemulsification were not related to the changes in CCT and there was no correlation between IOP and CCT changes in any time point.
