Abstract：[Abstract] Objective To analyze the morbidity situation of macular edema in patients with diabetic cataract after phacoemulsification. Methods The clinical data of 113 cases (122 eyes) of patients treated with cataract ultrasonic emulsification and intraocular lens implantation in Shandong Qingzhou Ophthalmic Hospital from January 2013 to January 2015 was analyzed retrospectively, the patients were divided into diabetic group (59 cases, 64 eyes) and non-diabetic group (54 cases, 58 eyes) according to the presence of diabetes. Occurrence of macular edema, vision improved conditions, and macular retinal thickness of central sunken area of the two groups before and after treatment were observed and compared. Results Three months after surgery, there were 22 eyes of macular edema in the diabetic group, the incidence was 48.44%; there were 5 eyes of macular edema in the non-diabetic group, the incidence was 8.62%, the incidence of macular edema in the diabetes group was obviously higher than that of non-diabetic group, the difference was statistically significant (P ＜ 0.05). Fluorescence fundus angiography examination showed that, diabetes patients showed mainly with leakage type of localized and diffuse leakage, the non-diabetic group was given priority to cystic oedema leakage, the leakage type between the two groups was statistically significant (P ＜ 0.05). One month after surgery, the best corrected visual acuity of non-diabetic group was obviously better than that of diabetes group, and macular retinal thickness of central sunken area was lower than that of diabetes group, the differences were statistically significant (P ＜ 0.05). Preoperative vision of the two groups had no statistically significant difference, postoperative visual acuity of two groups was improved significantly (P ＜ 0.05), and 1 week, 1 month, and 3 months after surgery, vision of patients in diabetes group was all lower than those of non-diabetic group, the differences were statistically significant (P ＜ 0.05). Conclusion The incidence of diabetic cataract patients with macular edema after phacoemulsification is significantly higher than that of non-diabetic cataract patients, and postoperative retinal thickness is increased, which significantly affects the recovery of vision.
