Abstract:
Background Trans-scleral fixation of intraoculalen(IOL) hamade greaprogress,buthe long-term stability of the implanposition of IOL aftesurgery inoideal.Objective Thistudy wato investigate the relevanfactorof IOL dislocation aftetrans-scleral fixation of IOL.Methodrespective case-observational study wadesigned.The clinical datfrom 321 eyeof 321 patientwho had received trans-scleral fixation of IOL were collected.total of 263 patientcompleted the effeetive follow-up,and 164 patientwith the follow-up fomore than 5 years.No IOL dislocation occurred within 5 yearin all 263 eyes.The relationship between IOL material,IOL implantation location,the time of IOL dislocation and the intraoculapressure with IOL dislocation were analyzed.ResultIOL dislocation appeared 7-10 yearaftesurgery in 9 eyewith an incidence rate of 5.49％.Breakage of IOL suture wafound in all the eyewith IOL dislocation.Dislocation wamore frequently found in IOL performed in the oblique position than thain the horizontal position (10.0％ vs.3.5％).The rate of IOL dislocation wahighesin traumatiretinal detachmeneyes,apercentage of 33.33％.Single piece IOL wamore easily dislocated.ConclusionThe breakage of anchosuturein IOL ileading cause of IOL dislocation aftetrans-scleral fixation of intraoculalens,which may be associated with the weighresulting from the fixation procesin non-level angulaIOL.Iirecommended thaIOL should be fixed in the horizontal position.
