Abstract：Objective To investigate the effects of phacoemulsification combined with artificial lens implantation on tear fluid of patients with diabetes mellitus (DM).Methods Thirty patients with simple senile cataract and 30 cataract patients with DM were divided into control group (n=30) and DM group (n=30).The symptoms scroes of xerophthalmia were performed on 7d,15d,1m,3m after the surgery,more over, the OCT was used to analyze lacrimal riuer height, tear fluid break-up time (break-up time, BUT) and SchirmnerⅠ measurement results.The detection results were analyzed and compared statistically between two groups.Results The symptoms scroes of dry eye in DM group were higher than those in control group on 7d, 15d,1m after surgery,however,there were no significant differences in the scores on 3m after surgery between two groups.The lacrimal riuer height and BUT on 7d,15d,1m,3m after surger in control group were higher than those in DM group,further more, SchirmnerⅠlenth in DM group was significantly decreased on 15d,1m,3m after surgery.Conclusion The syndromes of xerophthalmia in patients with DM are more severe and duration is more longer than those in patients with simple senile cataract after phacoemulsification.
