Purpose The aim of this study was to investigate the incidence of intraocular pressure (IOP) elevation after resident-performed cataract surgery and to determine variables, which influence postoperative day 1 (POD1) IOP. Methods In all, 1111 consecutive cataract surgeries performed only by training residents between 1 July 2001 and 30 June 2006 were included. Elevated IOP was defined as (greater-than or equal to)23 mm Hg. Surgeries were classified according to the presence of POD1-IOP elevation. Fisher's exact test and Student t-test were used to compare both groups. Multivariate analyses using generalized estimating equations were performed to investigate predictor variables associated with POD1-IOP elevation. Results The average preoperative IOP was 16.0(plus or minus)3.2 mm Hg and the average POD1-IOP was 19.3(plus or minus)7.1 mm Hg, reflecting a significant increase in IOP (P(less-than or equal to)0.001, paired t-test). The incidence of POD1-IOP elevation (greater-than or equal to)23 mm Hg was 22.0% (244/1111). Presence of glaucoma and ocular hypertension, higher preoperative IOP, and longer axial length were frequently encountered variables in the POD1-IOP elevation group (all P(less-than or equal to)0.05). Using a multivariate analysis, presence of glaucoma (P=0.004, OR=2.38; 95% confidence interval (95% CI)=1.31-4.30), presence of ocular hypertension (P=0.003, OR=6.09; 95% CI=1.81-20.47), higher preoperative IOP (P(less-than or equal to)0.001, OR=3.73; 95% CI=1.92-7.25), and longer axial length (P=0.01, OR=1.15; 95% CI=1.03-1.29) were significant predictive factors for POD1-IOP elevation. Conclusions IOP elevation on the first postoperative day following resident-performed cataract surgery occurred frequently (22.0%). Increased early postoperative IOP was associated with presence of glaucoma and ocular hypertension, higher preoperative IOP, and longer axial length.
