Application of three-dimensional visualization technology in phacoemulsification benefits the dry eye symptoms of patients after cataract surgery

PurposeTo investigate the effects of the three-dimension visualization system on dry eye in patients after cataract phacoemulsification.MethodsSeventy-one patients (104 eyes) were enrolled in this study and assigned to the conventional microscopic group (CM group) or three-dimension group (3D group). Ocular Surface Disease Index, The Schirmer I test (SIt), lipid layer thickness (LLT), noninvasive tear breakup time (NIBUT) and other factors associated with dry eye were recorded before and 1 week and 1 month after surgery. The operation time and intraoperative light intensity (ILI) were also recorded.ResultsThe ILI in the 3D group was significantly lower than that in the CM group (33% vs. 60%, p
