Purpose:To evaluate the clinical and visual outcomes,quality of near vision and the influence of photic phenomena in patients bilaterally implanted with a new Precizon Presbyopic multifocal intraocular lens(IOl).Methods:In this prospective consecutive case series,20 eyes of 10 patients were included(mean age 63.80±12.55 years).Uncorrected and corrected visual acuity(far,intermediate and near),subjective refraction,binocular defocus curve,contrast sensitivity(CSV-1000)and quality of vision and satisfaction questionnaires were *** follow-up was 12 months after ***:At 12 months after surgery,uncorrected distance visual acuity(UDVA)improved with surgery(p=0.001)with a value of 0.08±0.08 *** near visual acuity(UNVA)was 0.22±0.12 logMAR and distance corrected near visual acuity(DCNVA)was 0.16±0.13 *** distance visual acuity(UIVA)was 0.22±0.10 *** sensitivity outcomes were similar to normal population in photopic conditions and slightly reduced in mesopic conditions of *** curve showed that this multifocal IOl was able to provide a visual acuity(VA)equal or better to 0.16 logMAR between defocus levels of+1.00 to−2.50 *** patient satisfaction was obtained in quality of vision and satisfaction questionnaires ***:The Precizon Presbyopic NVA IOl(OPHTEC BV)provides good visual *** multifocal IOl provides a high percentage of spectacle independence due to good VA at far,intermediate and near distances and satisfactory contrast *** patient satisfaction was observed in quality of vision and satisfaction questionnaires with a low percentage of patients manifesting photic phenomena.

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 ***: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 *** 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 ***: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 *** 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 *** 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 ***,one eye developed retinal *** 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.
