Abstract Details


To survey members of the ASCRS/ESCRS regarding explantation of foldable IOL’s or foldable IOL’s requiring secondary intervention.


John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA


The survey was available to all ASCRS/ESCRS members throughout 2013. Surgeons filled out one form for each explanted foldable IOL. Preoperative data was collected as well as the type of IOL requiring explantation. The patients’ signs and symptoms as well as complications requiring explantation were tabulated. Lastly, postoperative results were assessed


Complications varied depending on the type of foldable IOL. Dislocation/decentration was the most common complication associated with one-piece silicone IOLs. Similarly, dislocation/decentration was seen as the most common reason for removal of three-piece silicone and one-piece acrylic lenses. Incorrect lens power as well as glare/optical aberrations were also noted in explantation of IOLs. The number of explanted multifocal IOLs increased over the past year. The most common reason for explantation of these lenses was glare/optical aberrations. Hydrophilic acrylic IOLs were removed most commonly due to calcification/opacification


The most common complications involving foldable IOLs have changed little over the past five years and may continue to be avoided by excellent surgical technique, quality manufacturing, careful IOL folding and insertion, and accurate IOL measurements. Multifocal IOLs are being explanted more frequently secondary to glare/optical aberrations
