Cataract/Anterior Segment, Premium IOLs
In this interview from AAO 2017, Dr. David Chang discusses results of a retrospective study comparing the rotational stability of 2 toric IOLs. The cohort included 628 consecutive patients who received the Alcon AcrySof and 648 who received the Tecnis toric IOLs at a single center. Dr. Chang notes that this study differs from other stability comparisons because the center’s physicians used the Callisto digital marking system to confirm the final IOL position during all operations. A recent investigation found that 28% of postoperative misalignment stems from misalignment during the procedure. Dr. Chang and his collaborator, Dr. Bryan Lee, found that though both IOLs showed good stability profiles, a higher percentage of patients with the Alcon model achieved alignment within 10 degrees or less compared with the Tecnis (98% vs. 93%).
