摘要
目的观察白内障超声乳化术中应用双氯芬酸钠水分离联合转核技术对后发障的预防作用。方法将72例（80只眼）老年性白内障患者随机分为4组分别行超声乳化术。A组使用生理盐水进行水分离，B组使用利多卡因水分离，C组使用双氯芬酸钠水分离，D组使用双氯芬酸钠水分离并联合转核。观察患者术后视力、角膜内皮细胞密度、晶状体后囊膜混浊（PCO）分级情况。结果各组术后各时期最佳矫正视力和角膜内皮细胞密度差异无统计学意义（P〉0．05）。各组后囊膜混浊分级差异有统计学意义（X^2=23．109，P〈0．001），C组和D组PCO分级低于A、B对照组，且D组PCO分级低于C组。结论双氯芬酸钠水分离联合核旋转能有效降低后发性白内障发生率，且眼内使用较为安全。
Objective To investigate the safety and effectiveness of hydrodissection with diclofenac sodium and nuclear rotation on the prevention of posterior capsular opacity. Methods Seventy two patients （ 80 eyes ） with age-related cataract were divided into four groups randomly and underwent phacoemulsifieation with IOL implantation. Hydrodissection was done with balanced salt solution in group A,with lidocaine in group B,with diclofenac sodium in group C,with diclofenac sodium and nuclear rotation in group D. Visual acuity, corneal endothelial cell density and grade of posterior capsular opacity were measured. Results There were no significant differences between four groups in the best corrected visual acuity and corneal endothelial cell density （P 〉0.05 ）. The PCO score of group C and D were lower than group A and D. Furthermore, the PCO score of group D was lower than group C. Conclusion Hydrodissection with diclofenac sodium and nuclear rotation is effective in preventing posterior capsular opacity and can be safely used in ophthalmic surgical practice.
