Data were derived from linear regression models. Continuous variables are reported as mean ± standard deviation. , statistical significance. CCT, central corneal thickness; DM, diabetes mellitus; IOP, intraocular pressure; PA, pressure to angle ratio; PD, pressure to depth ratio; PV, pressure to volume ratio; mm, millimeters; y, years. The remaining variables (DM duration, HbA1c levels, CDE, cataract grade, and IOL type) did not influence the model and were excluded.
