Abstract


Purpose: To investigate the long-term effect of phacoemulsification on intraocular pressure (IOP) in patients with medically controlled primary open-angle glaucoma (POAG).

Methods: This is a retrospective review of 120 eyes with POAG who underwent uncomplicated phacoemulsification with longitudinal follow-up. Demographic, clinical, and biometric variables such as age, axial length, central corneal thickness, gonioscopic results, anterior chamber depth, IOP, number of glaucoma medications were evaluated at 1, 2, 3, and 4 years after surgery.

Results: Postoperative IOP change through 1, 2, 3, and 4 years of -1.47 ± 2.59, -1.21 ± 2.48, -1.15 ± 1.68, and -0.98 ± 1.53 mmHg was statistically significant (p < 0.01). The number of glaucoma medications remained unchanged (p = 0.18). Higher preoperative IOP was significantly associated with greater postoperative decrease in IOP (p < 0.001). Four years after phacoemulsification, 81.3% of the POAG eyes maintained the same number of glaucoma medications while 14.6% had a decrease and 5.1% of the eyes required additional glaucoma medications.

Conclusions: After 4 years of phacoemulsification in patients with medically controlled POAG resulted in a very small IOP decrease without a change in the number of glaucoma medications. These findings have important implications when considering cataract surgery in POAG eyes for IOP reduction.
