摘　　要：Background:To evaluate the safety,efficacy,refractive outcomes and causes for bilensectomy(phakic intraocular lens–pIOL–explantation with cataract surgery and pseudophakic intraocular lens implantation)in patients previously implanted with posterior chamber pIOLs.Methods:This multi-center retrospective study included 87 eyes of 55 patients who underwent bilensectomy for posterior chamber pIOL with a follow up time of 12 months.The uncorrected and best corrected distance visual acuities(UDVA,CDVA),endothelial cell density before and after bilensectomy were assessed,as well as the cause of bilensectomy and intra or postoperative complications.Results:There was a statistically significant improvement in uncorrected and best corrected visual acuities after bilensectomy(p=0.00).The main reason for bilensectomy was cataract development(93.1%of the cases),followed by miscalculation of lens size,and corneal edema.The endothelial cell count remained stable without a statistically significant change after surgery(p=0.67).The refractive efficacy index was 0.8,none of the patients lost lines of CDVA after surgery,73%of the patients were within±1 D(spherical equivalent)of the target refraction.Intraoperative complications were one posterior capsule rupture with the intraocular lens(IOL)implanted in the sulcus,and 3 eyes required the use of pupil expanders for adequate pupil dilation.Postoperatively,one eye developed retinal detachment.The three pIOLs models explanted were the Implantable Collamer Lens(ICL),Implantable Phakic Contact Lens(IPCL)and the Phakic Refractive Lens(PRL).Conclusions:Good safety and visual outcomes were observed 1 year after bilensectomy for posterior chamber phakic intraocular lenses(PC pIOLs).There were few intra and postoperative complications and there was no significant endothelial cell loss after the bilensectomy procedure.
