RESUMO
Objective To discuss the effect of different cataract ultrasonic emulsification incision on the stability of the tear film after operation.Methods 82 patients (149 eyes) in our hospital from January 2010 to December 2012 were adopted as the research object.Patients were randomly divided into group A (40 cases,72 eyes) and group B(42 cases,77 eyes) used stratified random block method.Patients in group B were treated with anti-eyebrow scleral tunnel incision,and patients in group A were treated with corneal incision.The subjective feeling,tear secretion,tear film break-up time and the corneal incision staining of patients were compared and the results were analyzed between two groups.Results There were statistically significant differences in the subjective feeling of patients,the amount of tear secretion and the tear film breakup time (BUT) between the first day and the seventh day after operation.Conclusions Anti-eyebrow scleral tunnel incision is an ideal incision method for phacoemulsification.It has less impact on the stability of the cornea,and the damage to nerve is also light.
