方法：观察我院2012-03/2013-03糖尿病性白内障超声乳化术后的患者105例120眼作为观察组(糖化血红蛋白测定组、HbAlc<6.5%)。回顾我院2011-01/2012-03糖尿病性白内障行超声乳化术后的患者111例126眼作为对照组(血糖测定组、血糖<6.4mml/L)，均采用超声乳化联合人工晶状体植入术。术后随访，对两组术后患者眼前段炎症反应发生程度、视力恢复、抗生素使用强度(DDD)值进行对比。

结果：糖化血红蛋白测定组，平均视力恢复0.72，眼前段炎症反应发生率83.3%，抗生素使用强度为45.5。血糖测定组，平均视力恢复0.498，眼前段炎症反应发生率93.7%，抗生素使用强度为88.6。两组眼前段炎症发生率、反应程度及时间经统计学处理有明显差异(P<0.05)； 两组视力恢复程度P<0.05，有显著差异； DDD值有非常显著差异(P<0.01)。

结论：糖化血红蛋白测定是衡量患者术前血糖稳定的金指标，对糖尿病性白内障复明术手术时机选择有重要意义。术前糖化血红蛋白达标患者，眼前段炎症反应(TASS)的发生率明显降低； 术后视力恢复显著提高； 抗生素使用强度值显著降低。

METHODS: Totally 105 patients with diabetes(120 monocular)undergone phacoemulsification in our hospital from March 2012 to March 2013 were enrolled into the observation group(glycosylated hemoglobin determination group, HbA1c <6.5%). One hundred and eleven patients received diabetic cataract phacoemulsification surgery(126 monocular)in our hospital from January 2011 to March 2012 were reviewed as control group(blood glucose group, blood glucose <6.4mmL/L). Both of the groups were performed phacoemulsification with IOL intraocular lens implantation. Postoperative anterior segment inflammatory response(TASS), visual acuity and intensity of use of antibiotics(DDD)of the two groups' were compared during the following-up.

RESULTS:Glycated hemoglobin determination group: the mean visual acuity recovery was 0.72, the incidence of TASS was 83.3%, and DDD was 45.5. Blood glucose group: those were 0.498, 93.7%, and 88.6. The difference of incidence, degree and occurrence time of TASS(SAS 15.0 software analysis)and the degree of visual recovery between the two groups were statistically significant(P<0.05). The values of DDD were significantly different(P<0.01).

CONCLUSION:Glycosylated hemoglobin determination is the gold standard to measure blood sugar preoperation and has important significance for choosing the right time for diabetic cataract surgery. TASS was significantly reduced in the patients with preoperative standard glycosylated hemoglobin, the visual acuity of them improved significantly, and DDD values were significantly lower.
