    This prospective, nonrandomized study found that the dual-optic Synchrony accommodating IOL provides significantly better optical results than the single-optic Crystalens HD accommodating IOL.

    There is no question that these results are valid, given our experience with about 25 patients in the Synchrony trial. I only hope that FDA approval comes soon.

    The subjects were 39 cataract patients aged 59 to 82 years implanted with either a dual-optic (Synchrony) or single-optic (Crystalens) accommodating IOL.

    Both IOLs successfully restored distance vision, and both had similar limitations in providing adequate near visual outcomes at six months. However, the Synchrony lens provided significantly better contrast sensitivity and optical quality, as well as a significantly lower incidence of posterior capsule opacification (11.5 percent vs. 40.7 percent). The study's authors found no significant difference in reading acuity or reading speed between groups.

    They conclude that future long-term studies are required to confirm the stability of these IOL models in the capsular bag and the preservation of the visual outcomes found in this study.
