Dislocation, decentration most common causes of foldable IOL extractions

STOCKHOLM, Sweden — Dislocation and decentration were cited as the most common reasons for foldable IOL lens extractions, according a surgeon who reported on the results of a joint survey.

Nick Mamalis, MD, presented results of the ongoing foldable IOL survey at the European Society of Cataract & Refractive Surgeons (ESCRS) meeting. He said the joint survey, which have been available to members of the American Society of Cataract and Refractive Surgery (ASCRS) and ESCRS, were filled out by surgeons throughout 2006.

Survey results found that the most common complications with one-piece and three-piece acrylic IOLs were dislocation and decentration, followed by glare, aberrations and uveitis, Dr. Mamalis said. One-piece plate and three-piece silicone IOLs showed similar results. For hydrogel and hydrophilic acrylic lens, calcification or opacification were the main reasons for removal, he said. For multifocal lenses, glare and optical aberration were the main reasons for removal.

Dr. Mamalis requested that any surgeon performing a foldable IOL removal take part in the study by visiting the ASCRS or ESCRS Web site and filling out and submitting the survey form.
