AIM: To investigate the relationship between glycosylated hemoglobin(HbA1c)level and visual acuity, intraocular pressure, surgical complications, macular fovea retinal thickness after cataract surgery in diabetic patients.

METHODS: A retrospective analysis of diabetic patients submitted to cataract surgery over the period January 2018 to December 2018 in our hospital, a total of 56 cases(66 eyes)were selected and divided into normal HbA1C group(HbA1c≤6.0%)of 30 cases(34 eyes)and high HbA1C group(6.0%RESULTS: The BCVA after surgery were significantly improved in two groups. The differences between group A and group B(whether preoperative or postoperative)was not statistically significant(P>0.05). Postoperative complications included anterior chamber reaction, transient intraocular pressure, corneal edema, and macular edema. The incidence rate was significantly higher in group B(88%)than in group A(56%)(P=0.029). The retinal thickness of foveal was higher in group B than in group A, and higher postoperative than preoperative, and the postoperative thickening was more obvious in group B than in group A, and the differences were statistically significant(P<0.05).

CONCLUSION: Compared with the normal HbA1c group, the high HbA1c group had more postoperative complications, higher foveal thickness of the macula, and worse postoperative visual acuity. Therefore, preoperative HbA1c levels in diabetic patients may be related to complications after cataract surgery and foveal thickness of the macula.
