Abstract：Objective: To investigate the curative effect of split nuclear technique on small incision cataract in anterior chamber horizontal space. Methods: The 110 patients with simple age-related cataract treated in our hospital were divided into control group and experimental group according to the patients' voluntary choice of surgical methods. 51 patients in the control group with 56 eyes underwent cataract phacoemulsification, and 59 patients in the experimental group with 68 eyes underwent small incision cataract. Correlative analysis was conducted of visual acuity, astigmatism, central corneal thickness, and complications before and after treatment in the horizontal space of the anterior chamber. Results: Before operation, the visual acuity of the control group and the experimental group were all less than 0.5, and it was improved in both groups compared with that at 1d, 1mo, and 3mo after surgery (P<0.05). And the control group and the experimental group were compared with each other at the same time. The difference was small (P>0.05). The difference of corneal astigmatism in the control group and the experimental group was small (P>0.05) before operation, and the difference was greater than that before surgery (P<0.05), and as to the rest time, there was no difference (P>0.05); the central corneal thickness of the control group and the experimental group was not significant compared with that before the operation, 1 day, 1mo, and 3mo after the operation (P>0.05). At different time points, the central corneal thickness ratio was significantly larger 1d after the operation, compared with the preoperative period (P<0.05), and in the remaining time it was smaller (P>0.05). Compared with the control group, the incidence of postoperative adverse events in the experimental group was reduced and there was a statistical difference. (8.82% vs 21.43% χ2=5.257, P<0.05). Conclusion: Clip splitting technique on small incision cataract in anterior chamber horizontal space can effectively improve the visual acuity, and it is safe and worthy of clinical application.
