Purpose
To compare IOP changes after phacoemulsification in PXG patients with healthy cataract patients as controls, and to evaluate the factors associated with IOP reduction after phacoemulsification.
Setting
OPSIS Ophthalmology Institute, Kozani, Greece
Methods
This retrospective study included a total of 140 subjects who had undergone cataract surgery; 70 patients with medically controlled glaucoma (PXG), and 70 healthy cataract patients as control group. The IOP changes in the PXG patients were analyzed and compared with those in the control group until 2 years after phacoemulsification by linear mixed model after adjusting baseline IOP. An IOP reduction group was determined to be a greater than 20% drop at postoperative 2 years. Logistic regression analysis was used to find factors associated with IOP reduction after phacoemulsification in PXG.
Results
IOP was reduced after phacoemulsification by 19.11% at postoperatively 2 years for PXG patients, compared with 10.21% for the healthy cataract patients. According to the analyses, phacoemulsification resulted in greater IOP reduction for the PXG subjects, higher preoperative IOP was found to be a predictor of greater IOP reduction after phacoemulsification. The anterior chamber angle parameters did not demonstrate any significant association with IOP drop.
Conclusions
Phacoemulsification can have an additive IOP-lowering effect in medically controlled PXG for at least 2 years. Greater IOP reduction can be achieved for PXG patients having higher preoperative IOP.
