摘要
目的比较透明角膜切口与巩膜隧道切口白内障超声乳化手术对糖尿病患者术后泪膜功能的影响。方法选取糖尿病性白内障患者78例(90眼),随机分为2组,每组45眼,A组行透明角膜切口白内障超声乳化手术,B组行巩膜隧道切口白内障超声乳化手术。分别观察术前3d及术后1周、1个月、3个月角膜荧光素染色(conjunctive fluorescein staining,CFS)、基础泪液分泌试验(SchirmerⅠtest,SⅠt)和泪膜破裂时间(tear break-up time,BUT)3个指标,以测定患者的泪膜功能变化。结果 2组CFS评分均在术后1周升高,随后逐渐下降,A组升高和下降幅度较大(P<0.05);2组SⅠt和BUT均在术后1周下降,随后逐渐升高,A组下降和升高幅度较大(P<0.05);术后3个月2组CFS、SⅠt、BUT数值基本恢复至术前水平。结论巩膜隧道切口较透明角膜切口白内障超声乳化手术对糖尿病性白内障患者术后泪膜功能影响小。
Objective To investigate the influence of phacoemulsificaiton with the clear corneal incision and the scelrotic tunnel incision on tear film of diabetic patients.MethodsSeventy-eight cataract patients（90eyes）with diabetes were divided into two groups randomly：group A（45eyes）with clear corneal incision phacoemulsification and group B（45eyes）with sclerotic tunnel incision.Cornea fluorescein（CFS）,Schirmer Ⅰ test（SⅠt）and tear break-up time（BUT） were observed at 3 d preoperatively and 1 week,1 month and 3 months postoperatively to evaluate the changes of tear film.Results The CFS scores of two groups were obviously increased at 1 week postoperatively,and then gradually decreased.The increase and decrease in the clear corneal incision group were larger（P〈0.05）.The SⅠt and BUT of two groups were both obviously lower at 1week postoperatively than preoperatively（P〈0.05）,and then gradually increased.The increase and decrease in the clear corneal incision group were larger（P〈0.05）.There were no significant difference of CFS,SⅠt and BUT between two groups at 3months postoperatively（P〈0.05）.Conclusion Compared with clear corneal incision,the changes of tear film in sclerotic tunnel incision was slighter after phacoemulsification in cataract patients with diabetes.
