Objective To investigate the influence of intraocular lens(IOL)capsular complex morphology on the tilt and decentration of IOL.Methods It was a cohort study.Ultrasound emulsification combined with single-piece folded IOL capsular bag intraoperative implantation was performed in 121 cases(121 eyes)with age-related cataract.The morphol-ogy of IOL capsular complex was collected postoperatively by the slit lamp,and the direction and degree of the decentra-tion and tilt of the IOL in each group were measured by Pentacam.Results At 3 months after IOL implantation,the decen-tration of the full compression capsule group was smaller than that of the other three combined groups(t=-2.020,P<0.05)in 180-degree plane.The tilt of the nasal group was larger to the temporal side than the temporal group in the partial com-pression group in 180-degree plane(t=2.613,P<0.05).Conclusions All the edges of the anterior lens capsule tear are lo-cated on the optical surface of the IOL,which is the best complex morphology to ensure the orthotropic position of the IOL after the operation.
