Problems for Alcon's (US) non-silicone intra-ocular lens (IOL):

Executive Summary

Shortly after Alcon (US) introduced its acrylic intra-ocular lens some months ago, rumours of problems with the new product began to circulate. In April, it became official: there were problems with "glistening", the company informed surgeons and ophthalmologists, and began a voluntary recall. Alcon believes the culprit is the US packaging; no problems have been found in products sold overseas. Meanwhile, both Alcon and the FDA are investigating.
