Abstract：Objective To explore the effect of anterior chamber depth (ACD) before operation on refractive status in patients with age-related cataract after phacoemulsification. Methods A total of 123 patients with age-related cataract (123 eyes) in Xinjiang Uygur Autonomous Region People’s Hospital from April 2018 to April 2019 were collected as the research subjects. According to preoperative ACD, they were divided into high risk shallow anterior chamber group (35 cases), mild shallow anterior chamber group (46 cases), and normal anterior chamber group (42 cases). The parameters of diopter, ACD and so on were determined before, one day after and three months after operation. The correlation between ACD and refractive error was analyzed by Pearson product moment correlation. Results There were statistically significant differences in ACD among different groups and at different time points (P ＜ 0.05). Preoperative ACD of the high risk shallow anterior chamber group and the mild and shallow anterior chamber group were lower than those of the normal anterior chamber group, and the high and shallow anterior chamber group was lower than that of the mild shallow anterior chamber group (P ＜ 0.05). ACD of patients in the high and shallow anterior chamber group and the mild shallow anterior chamber group increased one day and three months after surgery compared with that before operation (P ＜ 0.05). There was no difference in refractive error among the three groups at one day after operation (P ＞ 0.05). Three months after operation, the refractive error of the high and shallow anterior chamber group and the mild and shallow anterior chamber group was greater than that of the normal anterior chamber group, and the high and shallow anterior chamber group was greater than that of the mild and shallow anterior chamber group (P ＜ 0.05). According to Pearson product moment correlation analysis, preoperative ACD of age-related cataract patients was negatively correlated with the refractive error three months after surgery (r = -0.759, P ＜ 0.05). Conclusion ACD is negatively associated with refractive error in patients with age-related cataract after phacoemulsification. Accurate preoperative evaluation of ACD has a great significance for clinical operation plan and improvement of postoperative diopter.
