“…Accurate identification of which patients will experience an IOP-lowering response could influence surgical decision-making, for instance determining when a cataract surgery alone would lower IOP adequately, or whether a concurrent glaucoma procedure is indicated [2, 14, 15]. Eyes with highest preoperative IOP have the greatest reduction in IOP in the long term [11].…”

The purpose of the study was to determine the independent predictors of long-term intraocular pressure (IOP) reduction after cataract surgery with phacoemulsification. This is a retrospective review of uncomplicated cataract surgeries from 2006 to 2008 at the Baltimore VA Medical Center with longitudinal follow-up. Demographic, clinical, biometric, and intraoperative variables including phacoemulsification parameters were recorded. Univariate and multivariate linear regression were used to analyze the relationship between these variables and postoperative IOP, which was the outcome variable. Analysis was performed in 115 eyes of 115 patients who underwent uncomplicated phacoemulsification during the study period. There was an average postoperative IOP reduction through 12, 24, and 36 months of −1.7 ± 3.1, −1.5 ± 3.8, and −1.3 ± 2.6 mmHg, respectively. Higher preoperative IOP (P < 0.001), a more anterior relative lens position (P < 0.05), and longer phaco time (P < 0.05) were significantly associated with greater postoperative decrease in IOP using univariate analysis. Using multivariate analysis, preoperative IOP (P <0.001), and phaco time (P = 0.038) were associated with greater postoperative IOP reduction through 24 months. Phaco time is independently associated with IOP reduction after adjusting for age and preoperative IOP. Higher preoperative IOP is associated with a greater IOP-lowering effect after phacoemulsification.

“…Although these indexes are neither validated nor globally implemented, they might be helpful when making decisions regarding which surgical procedure to perform, whether a simple lens extraction would suffice to control the IOP or a more invasive (yet more effective) procedure would be necessary. Finally, many other biometric factors have been proposed as independent predictors of post-operative IOP - anterior chamber area, anterior chamber width, lens thickness - but their usefulness warrants further investigation [20,24,25]. …”

Cataract surgery is one of the most performed surgeries in the developed world. In addition to its significant impact on visual acuity, phacoemulsification has been hailed as a potential intraocular pressure (IOP)-lowering procedure. While current evidence suggests an overall significant and sustained decrease in IOP to exist after cataract surgery, the specific ocular characteristics that could help predict which patients are likely to benefit from this IOP-lowering effect remain unclear. This definition is important in glaucoma patients if this surgery is to be used in the treatment for this disease. Our review aims to summarize the literature on the subject, depicting possible mechanisms behind this IOP decrease, which type of patients are more likely to benefit from this surgery for IOP-lowering purposes and ultimately help optimizing disease management for the increasing number of patients with concomitant glaucoma and cataract.

“…3 Strikingly, Ohsugi and associates 4 reported that choroidal thickness increased after cataract surgery and the changes in choroidal thickness were negatively correlated with IOP changes (early after surgery) and the axial length (in the late postoperative period). We also conducted research about choroidal thickness changes after cataract surgery and, consistent with Ohsugi and associates' findings, we found that phacoemulsification surgery causes a significant increase in the choroidal thickness, which is correlated with surgeryinduced IOP change in the short term (http://www.escrs.…”

“…2 Furthermore, it has been reported that hyperbaric oxygen can control inflammation and vasculogenesis by decreasing neutrophil adherence and downregulating the expression of intercellular adhesion molecule-1 and vascular endothelial growth factor. 3 Hyperbaric oxygen can improve the potency of antibiotics and has antibacterial effects as well. 4 Finally, hyperbaric oxygen stimulates the defense mechanisms against oxidative stress that plays a critical role in chemical injuries such as mustard-induced burns.…”
