Correlation coefficients between underestimated IOP (ΔGAT and ΔncIOP) at 3 months for six parameters
| ΔGAT (correlation coefficient†) | 95% CI | p Value | ΔncIOP (correlation coefficient) | 95% CI | p Value | |
|---|---|---|---|---|---|---|
| Δ, difference between the preoperative and the 3 month postoperative data; CI, confidence interval; GAT, Goldmann applanation tonometric intraocular pressure; ncIOP, non-contact tonometric intraocular pressure; CCT, central corneal thickness. | ||||||
