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.

After the first secondarily-transmitted ebola case in Spain, a wave of divergent opinions flooded mass and sanitary media. Very few of these opinions, however, came from experts on epidemiology or hemorrhagic fevers. This observational study aimed to assess the specific knowledge of Primary Care physicians and nurses about ebola and hemorrhagic fevers by means of analyzing the results obtained from a 5-item self-reported questionnaire dealing on hemorrhagic fevers basic knowledge. Validity and reliability of questionnaire were confirmed by a pilot study. The participants were 138 family doctors and nurses from the 64 public Primary Care centers sited in the North Metropolitan Area of Barcelona (1,400,000 inhab;catalonia, Spain) taking part in training-the-trainers ebola workshops. Overall, there were 117 (84.8%) respondents out from 138 workshop participants;of them were physicians 61 (51.2%). The main age was 46.7 (8.8) years;stating previous specific knowledge on hemorrhagic fevers 39 (33.3%). On the whole, up to 92 (78.6%) of respondents shown a poor knowledge. Previous specific formation was significantly and independently associated with having proper knowledge (p < 0.001);OR = 8.6 (CI 95%: 3.199 - 23.623). In summary, confusion that accompanied the single secondary-transmitted ebola case in Spain could probably be explained by the existence of a serious gap on hemorrhagic fevers knowledge. More accurate, scientific and formally-presented information should be provided to Primary Care physicians and nurses.
