Abstract
PURPOSE: To analyze changes in intraocular pressure (IOP) after cataract surgery based on data from the Swedish National Cataract Register (NCR). SETTING: Ophthalmic surgery units in Sweden. DESIGN: Prospective database study. METHODS: Data for 2012 through 2014 were obtained prospectively from the NCR. The outcome register of the NCR has collected data on IOP before and a mean of 37.7 days ± 29.1 (SD) after cataract surgery since 2012. RESULTS: The analyses were based on 20 437 cataract extractions reported during 1 month each year to the outcome registry of the NCR. Cataract surgery was found to reduce IOP by a mean of 1.46 mm Hg, which was statistically significant (P < .001). A larger IOP reduction was seen in cases with a higher preoperative IOP (r = 0.557, P < .001). Older patients and shorter eyes had a greater IOP reduction after surgery (P < .001 and P = .001, respectively). Women had a greater IOP reduction than men (P = .04) When high IOP was given as an indication for surgery, the IOP reduction after cataract surgery was 5.50 mm Hg compared with a reduction of 1.40 mm Hg in patients for whom this indication was not given (P < .001). Patients with glaucoma or pseudoexfoliation (PXF) had a more pronounced IOP reduction than patients without these diagnoses (P < .001). CONCLUSION: Cataract surgery had an IOP-lowering effect, in particular in older patients, women, short eyes, eyes with high preoperative IOP, and eyes with glaucoma or PXF.
