Analysis of dry eye after phacoemulsification in patients of renal transplantation

Objective To analyze the change of tear film after phacoemulsification in patient with renal transplantation and discuss the problem of dry eye.Methods A non-randomized cases-controlled study was designed.26 cataract patients with renal transplantation (the experimental group) (34 eyes) and matched 33 patients (40 eyes) with age-related cataract(control group) were included in this study.Before and after different time phacoemulsification and IOL implantation respectively was performed on the all patients,dry eye-related symptom was surveyed and scored by questionnaire,and tear film break-up time (BUT),Schirmer I test (SIt) and corneal fluorescein (FL) were examined.Results The experimental group is significantly heavier than control group obviously postoperatively in patients with dry eye symptom score,FL,BUT,the overall differences were statistically significant(P ＜ 0.05),but after 3 months FL preoperatively with no significant difference (P ＞ 0.05).Conclusion Tear film function of renal transplantation patients is poor after cataract phacoemulsification.And are susceptible population for dry eye.Dry eye appears more early and severer in renal transplantation patients after phacoemulsification combined with IOL implantation.
