| Abstract;Purpose: To compare the long-term clinical and experimental results of soft acrylic intraocular lenses(IOLs) manufactured by the lathe-cut(LC) method and by the cast-molding (CM) method. Methods: This was a retrospective study of 20 patients (22 eyes) who were examined in a 5- and 7-year follow-up study. Sixteen eyes were implanted with polyacrylic IOLs manufactured by the LC method and 6 eyes were implanted with polyacrylic IOLs manufactured by the CM method. Postoperative measurements included best corrected visual acuity, contrast sensitivity, biomicroscopic examination, and Scheimpflug slit-lamp images to evaluate surface light scattering. Scanning electron microscopy and three-dimensional surface analysis were conducted. Results: At 7 years, the mean visual acuity was 1.08.+-.0.24(mean.+-.standard deviation) in the LC group and 1.22.+-.0.27 in the CM group. Surface light-seatter was 12.0.+-.4.0 computer compatible tapes (CCT) in the LC group and 37.4.+-.5.4 CCT in the CM group. Mean surface roughness was 0.70.+-.0.07nm in the LC group and 6.16.+-.0.97nm in the CM group. Conclusion: Acrylic IOLs manufactured by the LC method are more stable in long-termuse. (author abst.) |
