Nursing of tear film to prevent occurrence of dry eye syndrome following phacoemulsification in diabetics

Objective:To evaluate tear film changes and dry eye syndrome following phacoemulsication in diabetics.Methods:This randomized study involved 58 cases(66 eyes) with diabetes cataract and 50 cases(50 eyes) with cataract who underwent phacoemulsification. Tear break-up time(BUT),SchinmerⅡtest(SIt) value and corneal fluorescein staining(FL) were measured preoperatively and 1 d,7d,30d postoperatively.Results:At 1 d,3 d and 7 d postoperatively,the subjective complains of dry eye,the mean SIt and FL scores increased significantly,and the mean BUT decreased significantly(P0.01).In addition,the mean BUT and SIt of diabetes group was less than those of normal group preoperatively and 30 d postoperatively(P0.05).The score of corneal FL of diabetes group was higher than that of normal group.Conclusion:Phacoemulsification reduces the stability of tear film of diabetic patients.Preventions should be taken, like artificial tears.
