Abstract Details


In a retrospective study the reasons and the techniques for IOL explantation have been analyzed


Eye Institute University of Florence


In a group of 9142 cataract surgery patients, operated in a 8-year period between 2002 and 2009 the reasons for IOL explantation have been studied. The technique adopted to remove the IOLs have been studied.


An overall IOL explantation rate of 0.46% (42 eyes) was found. The main cause was lens dislocation 61.94% (26 eyes) followed from significant refractive surprises 21.42% (9 eyes), dysphotopsyc phenomena in patients implanted with a multifocal IOL 11.90% (5 eyes) and lens opacification 4.76% (2 eyes).


The need to explant an intraocular lens is today rare but it is very important to choose the best surgical technique for any case to avoid severe complications.In fact surgical protocol and explantation techniques vary according to the time enlapsed between the two surgeries.
