postoperative corneal sensitivity; however, no signifi cant changes were detected in the intergroup compar isons. (4) Group B had an 8.2% reduction in ECC, significantly higher than in the rest of the groups (Group A1: 4.8%; Group A2: 5.0%). (5) Endothelial cell loss showed linear correlation with CDE (Group B: r Z 0.47; Group A2: r Z 0.81; both P ! .01) (Figure 1). (6) Group A2 patients had significantly worse scores on the subjective discomfort index. The clinical significance of our study is that in energy-demanding cataracts, the combination of dispersive and cohesive OVDs seems to protect the endothelial cells more efficiently than the cohesiveonly OVD (Visthesia). That is, for the same CDE, more endothelial cells were lost in the cohesive-only OVD patients. Moreover, the endothelial loss pattern in these patients was more random than the in the dispersive–cohesive OVD (Duovisc) patients. How ever, although statistically significant, the increased endothelial loss in the cohesive-only OVD patients did not interfere with postoperative visual acuity or corneal thickness. On the other hand, the subjective discomfort feeling was significantly more pronounced in the dispersive–cohesive OVD patients; therefore additional intracameral anesthesia is considered to be necessary. The intracameral anesthesia we used in our study provided anesthesia comparable to that of the cohesive-only OVD, with no evident impact on endothelial cells. In summary, we consider that Visthesia and Duovisc offer comparable surgical outcomes in stage 3 cataract extraction surgery using torsional intelligent phaco technology. Despite the fact that the international liter ature provides conflicting comparative outcomes regarding the efficacy of the several commercially available OVDs, our results suggest that Duovisc provides an additional significant protective effect on endothelial cells that should be taken into consider ation, especially in cases with a low preoperative ECC.

BACKGROUND To date, studies on the role played by cigarette smoking in primary open-angle glaucoma (POAG) remains controversial. The current study evaluated cigarette smoking as a risk factor of POAG and its relationships with vertical cup-to-disc ratio (VCDR), central corneal thickness (CCT) and intraocular pressure (IOP) in a Chinese cohort. METHODS In a total of 248 unrelated individuals i...
