The aim of the research was to evaluate the effect of cataract surgery on intraocular pressure (IOP) and its long-term fluctuations in patients with Primary open angle glaucoma (POAG), Primary angle closure/Primary angle closure glaucoma (PAC/PACG), Pseudoexfoliation glaucoma (PXG) and in non-glaucomatous patients.
The study was conducted in Clinic for Eye Diseases of the University Clinical Centre of the Republic of Srpska, Bosnia and Herzegovina
A prospective intervention clinical study included a total of 124 patients (124 eyes) divided into four groups of 31 patients (31 eyes) who underwent phacoemulsification with intraocular lens implantation. The three experimental groups consisted of patients with POAG, PAC/ACG and PXG and with coexisting cataract. The fourth control group consisted of patients only with senile/presenile cataract. Patients were examined preoperatively, 1st, 3rd and 6th month postoperatively. The average IOP (IOPav) were calculated from diurnal tension curves test of intraocular pressure (measurements at 07:30; 13:30; 19:30) using a Goldmann applanation tonometer. Long-term postoperative IOP fluctuations were also evaluated.
When compared to preoperative values, in all groups there was a significant and sustainable reduction of IOPav postoperatively. For all experimental groups, the largest reduction of IOPav was in the 6th month (PAC/PACG: -4.14 mmHg, -22.18%; PXG: -3.23 mmHg, -17.67%; POAG: -2, 73 mmHg, -15.6%), and for the control group in the 3rd month (-2.44 mmHg; -16.4%). A significant negative correlation between the preoperative IOPav and their postoperative change was established in all groups. Long-term IOP fluctuations in POAG, PAC/PACG and Cataract groups show that the effect of cataract surgery on the lowering of IOP weakens over time.
Cataract surgery results in the reduction of IOP and the degree of reduction and its durations depends on the type of glaucoma
