糖尿病患者小切口非超声乳化白内障囊外摘除及人工晶状体植入术的疗效观察

目的 分析糖尿病患者行小切口非超声乳化白内障囊外摘除及人工晶状体植入术的临床疗效及并发症。方法48例(53只眼)糖尿病白内障患者和45例(53只眼)非糖尿病白内障患者行小切口非超声乳化囊外摘除及人工晶状体植入术。结果 糖尿病组的术后40只眼(75.5％)矫正视力≥0.5;非糖尿病组术后矫正视力≥0.5者共45只眼(84.9％)。两组术后视力和术后并发症均无显著性差异(P>0.05)。但糖尿病患者中,术前瞳孔不能充分散大或术中瞳孔缩小的病例明显多于非糖尿病患者,经统计学处理差异有显著性(P<0.05)。结论 糖尿病患者在血糖控制稳定的情况下行小切口非超声乳化白内障囊外摘除及人工晶状体植入术可明显改善视力,术中、术后并发症的发生率、术后视力的提高,与一般非糖尿病患者相比差异无显著性,说明小切口非超声乳化白内障囊外摘除及人工晶状体植入术治疗糖尿病患者白内障是安全有效的,视力改善与糖尿病视网膜病变的程度有关。

An investigation on therapeutic results of nonphacoemulsification extracapsularcataract extraction with mimi - incision and intraocular lens implantation in diabetics

Objectives To investigate the therapeutic results and complications of nonphacoemulsificalion cataract extraction with mimi - incision and intraocular lens implantation in diabetics. Method There were two groups of cataract patients, including 48 diabetics with or without diabetic retinopathy and 45 nondiabetics. Two groups were treated with nonphacoemulsificalion extracapsular cataract extraction with mimi - incision and intraocular lens implantation. Results The post - operative corrected visual acuities of 0.5 or better were achieved in 40 of 53(75 .5% ) diabetic eyes and in 45 of 53(84.9% ) nondiabetic eyes. The comparision between the two groups showed that there was no significant difference in intra - operative or post - operative complications(P > 0.05) . Conclusion nonphacoemulsification extracapsular cataract extraction with mimi - incision and intraocular lens implantation in diabetics was safe and effective if their blood sugar was controlled well. The post - operative corrected visual acuities related the grade of diabetic retinopathy.
