Objective:To explore the effect of phacoemulsification in combined with intraocular lens implantation incision site selection on the visual function, intraocular pressure, and corneal astigmatism in patients with cataract.Methods:A total of 72 patients (85 eyes) with cataract who were admitted in our hospital from April, 2015 to October, 2016 were included in the study. All the patients were performed with phacoemulsification in combined with intraocular lens implantation. The patients were divided into the observation group (n=36, 43 eyes) and the control group (n=36, 42 eyes) according to different surgical incision sites. A transparent corneal incision with a length of 3.0 mm was made along the meridian axial position with the maximum corneal refractive power in the observation, while a transparent corneal incision with a length of 3.0 mm was made above the temple or nose in the control group. Routine disposition and follow-up visit were given for the patients in the two groups after operation. BCVA, intraocular pressure, corneal astigmatism, and corneal endothelial cell count in the two groups before and after operation were compared.Results:BCVA after operation in the two groups was significantly elevated, while the corneal endothelial cell count was significantly reduced, but the comparison of BCVA and corneal endothelial cell count between the two groups was not statistically significant. The intraocular pressure after operation in the two groups was elevated first and reduced later. The intraocular pressure 2 h and 1 d after operation was significantly elevated when compared with before operation. The intraocular pressure 2 d after operation was not significantly different from that before operation. The comparison of intraocular pressure at each timing point after operation between the two groups was not statistically significant. The corneal astigmatism after operation in the two groups was elevated first and reduced later. The surgically induced astigmatism 7 d-6 months after operation was significantly reduced, and the average corneal astigmatism 7 d-6 months after operation in the observation group was significantly lower than that in the control group. The surgically induced astigmatism 1-6 months after operation in the observation group was significantly lower than that in the control group.Conclusions: Phacoemulsification in combined with intraocular lens implantation incision site selection including maximum corneal refractive power site and routine surgical incision can improve the patients' vision, but the maximum corneal refractive power site surgical incision can reduce the postoperative corneal astigmatism, and has a certain advantage.
