Changes and influencing factors of the tear film after phacoemulsification

Objective To study changes and influencing factors of the tear film after phacoemulsification combined with intraocular lens implantation.Methods Sixty patients(70 eyes) with age-related cataract who underwent phacoemulsification combined with intraocular lens implantation were selected,and the chief complaint of dry eye syndrome,Schirmer I test(SIT),tear breakup time(BUT),corneal fluorescein staining(FSC)and corneal sensitivity values were analyzed before and 1 day,1 week,2 weeks and 1 month after operation.Results Compared with the data before operation,the complaint,SIT,BUT and FSC scores had statistically significant differences 1 day,1 week and 2 weeks after operation(P0.05),while there was no statistically significant difference 1 month after operation(P0.05).Corneal sensitivity returned to the preoperative level at 1 month postoperatively.Conclusion Phacoemulsification combined with intraocular lens implantation significantly affects the tear film function in the short term,and some patients may have dry-eye syndrome after surgery.Tear film stability has a significantly positive relationship with corneal sensitivity.
