摘要
目的 比较Ⅱ型糖尿病与非糖尿病患者超声乳化人工晶状体植入术后早期角膜水肿程度及恢复能力。方法 用超声角膜测厚仪对两组患者共 68眼手术前、后的角膜厚度进行测量。结果 非糖尿病组术后 1、7天时角膜中心厚度较术前增加(P <0 0 5 ) ,15、3 0天时和术前差异无显著性 (P >0 0 5 ) ;糖尿病组术后 1、7、15天时角膜中心厚度较术前增加 (P <0 0 5 ) ,3 0天时和术前差异无显著性 (P >0 0 5 ) ,显示角膜水肿恢复更缓慢。另外 ,两组间角膜厚度比较 ,术前和术后 3 0天差异无显著性 (P >0 0 5 ) ,而术后 1、7、15天时糖尿病组较非糖尿病组角膜厚度增加(P <0 0 5 )。结论 对Ⅱ型糖尿病患者应更注重手术的精巧 ,以减轻早期角膜水肿的程度 。
Objective To compare phacoemulsification and IOL implantation induced early corneal edema and ability of recovery between type 2 diabetic and nondiabetic patients.Methods Corneal thickness was measured with ultrasonic pachymeter in 39 eyes of type 2 diabetic patients and 29 eyes of nondiabetic patients before and after operation.Results The increase of corneal thickness after operation is mainly at the central part in both groups.In the nondiabetic group,the corneal thickness increased at 1 d,7 d postoperation ( P <0 05),and not significant at 15 d,30 d postoperation ( P >0 05).In the type 2 diabetic group,the corneal thickness inceased at 1 d,7 d,15 d postoperation ( P <0.05),and not significant at 30 d postoperation (P>0 05).It suggests that patients with type 2 diabetes have slower rate of corneal edema recovery.Moreover,diabetic group have more obvious corneal edema at 1 d,7 d,15 d postoperation ( P <0.05),but the difference between two groups before operation and 30 d after operation is not significant ( P >0.05).Conclusion The vulnerability of endothelium,more obvious corneal edema and decreased corneal edema recovery ability of the patients with type 2 diabetes suggest that much care should be taken when performing phaco+IOL in these people.
