Abstract;We followed up 27 eyes of 27 patients that received intraocular lens (IOL) implantation. We paid particular attention to possible discoloration of IOL. These 27 eyes were implanted with acrylic IOL produced by HOYA (VA60CA). Dark brown discoloration of IOL was detected in 4 eyes. The interval between surgery and detection of discoloration was 3 weeks, 4 months, 5 months and 10 months respectively. There were no problems about visual acuity or subjective findings ascribable to discoloration. The discoloration remained stable after detection. Three out of these 4 cases underwent implantation of acrylic IOL in the fellow eye of another brand. No discoloration developed in these 3 eyes. There has been no instance of discoloration since we started using VA60CB, an improved version of VA60CA, since one year ago. There is a possibility that the observed discoloration was due to unidentified flaw during the production or storage of VA60CA. (author abst.)
