摘要

Objective: To explore the clinical effect of lens capsules tension reducing capsulorhexis and conventional capsulorhexis in the white cataract phacoemulsification. Methods: A total of 68 patients (76 eyes) with white cataract who were admitted in our hospital from June, 2011 to June, 2016 were included in the study and divided into the experiment group (n=34, 36 eyes) and the control group (n=34, 40 eyes) according to the difference of intraoperative capsulorhexis. All the patients were performed with cataract phacoemulsification in combined with intraocular lens implantation. The patients in the experiment group were performed with lens capsules tension reducing capsulorhexis, while the patients in the control group were performed with conventional capsulorhexis. The integrity of the anterior capsule capsulorhexis, the degree of corneal endothelium edema, the intraocular lens deviation, uncorrected visual acuity, and corneal endothelial cell count in the two groups were compared. Results: A total of 34 eyes (94.44%) in the experiment group and 35 eyes (87.50%) in the control group successfully completed continuous annular capsulorhexis, and there was no significant difference between the 2 groups. The number of patients whose uncorrected visual acuity was greater than 0.5 increased 1 d-6 months after operation, and that in the experiment group was significantly higher than that in the control group. The difference of intraocular lens deviation rates between the 2 groups at different times after operation was not significant. The corneal endothelial cell count 1 d-6 months after operation in the 2 groups was significantly decreased when compared with before operation, but the difference between the 2 groups was not significant. The number of eyes without edema in the experiment group 1d after operation was significantly higher than that in the control group, and the number of eyes with grade Ⅱ edema was significantly less than that in the control group. Conclusions: The method of reducing capsulorhexis can make white cataract patients get better vision after operation, and reduce the degree of corneal edema, with higher clinical application value.
