ABSTRACT
Purpose: Angle?based surgeries for the treatment of open?angle glaucoma have gained popularity in recent years. This study aimed to evaluate the efficacy of combined phacoemulsification and goniotomy in primary open?angle and pseudoexfoliation glaucoma (POAG and PXG) and ocular hypertension (OHTN). Methods: In this interventional case series in the setting of the Glaucoma Service at the Farabi Eye Hospital, 32 eyes of 30 patients with early?to?moderate POAG and PXG and OHTN were enrolled. All eyes underwent combined phacoemulsification and needle goniotomy. Intraocular pressure (IOP) and the number of antiglaucoma medications as well as demographic data were recorded at baseline and one day, one week, one month, three months, and six months after the surgery. Generalized Estimating Equation (GEE) was used to compare the values of IOP and the number of medications at different time points. Kaplan–Meier graph was used to demonstrate the survival status of the eyes. Results: Mean IOP at baseline was 21.8 ± 4.6 mmHg on mean 1.2 ± 1.5 topical medications. There was a 25.2% (16.3 ± 4.5 mmHg) and 32.1% (14.8 ± 3.9 mmHg) reduction in IOP at three and six months after procedure, respectively (P < 0.001). Meanwhile, the decline in medications was 66.7% (0.4 ± 0.9) and 50.0% (0.6 ± 1.1) at the same time points (P = 0.002 and P = 0.048, respectively). Post?operative complications were clot hyphema (n = 1, 3.1%), fibrinous inflammation (n = 1, 3.1%) and distorted pupil (n = 2, 6.3%). Conclusion: Combined phacoemulsification and needle goniotomy as a procedure for mild and moderate POAG and PXG and OHTN is as effective as other modified goniotomies in the setting of minimally invasive glaucoma surgeries (MIGS)
