The changes of tear film after phacoemulsification combining with intraocular lens implantation

Objective To study the changes of tear film after phacoemulsification combined with intraocular lens implantation.Methods Forty cases(50 eyes) with age-related cataract who underwent phacoemulsification combined with intraocular lens implantation were chosen and the subjective complaints of dry eye,tear break-up time,corneal fluorescein staining and Schirmer I test(SIT) value were analyzed preoperatively and 1 day,1 week,1 month and 3 months postoperatively.Results Comparing with the data before operation,the complaints 、SchirmerⅠtest and tear break-up time(BUT) 、corneal fluorescein staining scores were all of statistical significance(P0.05) on the first day、1 week and 1 month after operation respectively,but 3 months after operation they had no statistical significance(P0.05).Conclusion Phacoemulsification combined with intraocular lens implantation significantly alters tear film in a short term,and some patients may have dry eye syndrome after surgery.
