Complications of foldable intraocular lenses requiring explantation or secondary intervention--2001 survey update.
A survey of the complications associated with foldable intraocular lenses (IOLs) that required explantation or secondary intervention was sent to members of the American Society of Cataract and Refractive Surgery and the European Society of Cataract and Refractive Surgeons. Preoperative data about visual acuity, patient signs and symptoms, and complications requiring IOL removal were assessed. Postoperative results and outcomes were also analyzed. Complications and symptoms for each of the following major groups of foldable IOLs explanted were tabulated separately: 3-piece hydrophilic acrylic or hydrogel; 3-piece monofocal silicone; 3-piece hydrophobic acrylic; 1-piece hydrophobic acrylic with haptics; 3-piece multifocal silicone; 1-piece plate-type silicone. A total of 286 surveys were returned for evaluation. Intraocular lens calcification, incorrect lens power, optical visual aberrations, and decentration/dislocation were the most common reasons for removing a foldable IOL. Accurate IOL measurements, meticulous surgical technique, proper patient counseling, and careful manufacture of foldable IOL materials are the most important factors in avoiding complications with foldable IOLs.
