    Study: Visual acuity outcomes similar, but FLACS has some advantages

    Better refractive prediction with FLACS than manual surgery

    Femtosecond laser-assisted cataract surgery (FLACS) facilitated a precise capsulotomy and reduced phaco energy in a recent ongoing study with about 100 consecutive eyes, said Jeffrey Whitman, MD, Key-Whitman Eye Center, Dallas.

    The study focuses on tracking the benefits of FLACS over manual cataract surgery in relation to visual acuity and refractive predictability in eyes receiving an accommodating IOL (Crystalens or Trulign, Bausch + Lomb).

    The eyes in the prospective study were randomly divided to receive FLACS or manual surgery; in the FLACS arm, a femtosecond laser (Victus, Bausch + Lomb) was used for primary corneal incision, capsulotomy, and lens fragmentation. The same surgeon performed all cases, Dr. Whitman said.

    At 90 days after surgery, distance, intermediate, and near visual acuity were measured. Postoperatively, the mean uncorrected distance visual acuity was nearly identical--20/30 in the laser group and 20/31 in the manual group.

     

    In the laser group, 28% were 20/20 or better, compared with 30% in the manual group. In the FLACS group, 70% of patients were 20/30 or better compared with 64% in the manual group, and 80% were 20/40 or better, compared with 76% in the manual group.

    The mean uncorrected intermediate visual acuity was nearly the same--20/17 and 20/18 in the laser and manual surgery groups, respectively. Ninety-eight percent were 20/25 or better in the laser group compared with 92% in the manual group, Dr. Whitman said.

    For uncorrected near visual acuity, the mean was also almost identical--20/28 and 20/27 in the FLACS and manual groups, respectively. Twenty-eight percent versus 24% of patients were 20/20 or better in the FLACS versus manual groups, respectively. Seventy-four percent versus 84% were 20/30 or better; and 90% versus 92% were 20/40 or better, respectively.
