Approved by the FDA in March 2005 for use in cataract patients with or without presbyopia, Alcon's AcrySof ReSTOR lens is the first apodized diffractive intraocular lens (IOL) to be made available. The approval was granted based on clinical trials which found that patients experienced the highest level of freedom from glasses ever achieved in IOL clinical trials.
Major advances have been made in the understanding of the pathogenesis of posterior capsule opacification (PCO) post-cataract surgery, and improvements in surgical technique and lens biocompatibility and design have reduced the rates of opacification in recent years. Nonetheless, opacification remains an important complication in patients undergoing phacoemulsification or extracapsular cataract extraction combined with intraocular lens (IOL) placement, with approximately up to 25% of patients developing visually significant PCO during the first five years post surgery.
