Effects of phacoemulsification on the intraocular pressure and corneal endothelial cells of the patients with glaucoma

摘要

Objective:To explore the intraocular pressure and corneal endothelial cells integrity changes in cataract phacoemulsification after anti-glaucoma surgery.Methods:Phacoemulsification was performed in 102 patients (118 eyes) with cataract after anti-glaucoma surgery and the intraocular pressure and corneal endothelial cell integrity changes of patients were observed at Day 1 and 3, first week and first month before and after surgery, including central corneal endothelial cell density, average cell area (AVE), cell area of coefficient of variation (CV) and central corneal thickness (CCT).Results:The intraocular pressure was elevated, the central endothelial cell density was reduced, the AVE, the CV and CTT thicken were increased at Day 1 and 3, first week and first month after surgery. The difference compared with preoperative was statistically significant. The intraocular pressure and CTT almost recovered to preoperative levels in 1 month after cataract phacoemulsification and the difference was not statistically significant; while the central endothelial cell density was still decreased and AVE and CV were still increased and the difference of these indexes and the coefficient of the patients was statistically significant compared with before surgery.Conclusions:For the patients with anti-glaucoma after cataract phacoemulsification, intraocular pressure and endothelial cell integrity change was initially observed at Day 1 after surgery, whereas they can almost return to the preoperative level in a month after surgery.
