    New laser system simplifies astigmatism correction

    State-of-the-art software increases efficiency, accuracy

    Lake Villa, IL—Use of a proprietary femtosecond laser system (LENSAR Laser System, LENSAR) is making astigmatism correction easy, efficient, and more accurate, according to Mitchell A. Jackson, MD.

    A software upgrade introduced in 2015 (Streamline) enables wireless transmission of preoperative topography data and an infrared image of the undilated eye to the laser. Intraoperatively, iris registration automatically adjusts for cyclorotation, eliminating the need to mark the cornea.

    Arcuate incision planning using the nomogram the surgeon programmed into the laser is completed at the touch of a button by selecting the “Surgeon’s Table” tab located on the LENSAR programming screen. The treatment is delivered accurately due to the iris registration, using the system’s software for marking the refractive steep corneal axis and placing precise astigmatic incisions (Intelligent Incisions).

    “LENSAR with Streamline brings automation, customization, and precision to planning and execution of astigmatism correction, and it has allowed me to consistently deliver predictable outcomes,” said Dr. Jackson, founder and chief executive officer, JacksonEye, Lake Villa, IL.

    Dr. Jackson explained the steps involved in performing astigmatic correction with the LENSAR femtosecond laser and provided tips to surgeons for optimizing success.

    Currently, wireless integration with the laser is available only when using the Cassini Corneal Shape Analyzer (i-Optics), but compatibility with the OPD-Scan III (Marco Ophthalmics) is coming soon.

    One advantage of the Cassini is that it measures total, posterior, and anterior corneal astigmatism, Dr. Jackson said. Although the LENSAR software currently only uses the anterior surface data for astigmatism planning, a future software upgrade will allow surgeons to choose between the anterior and total corneal astigmatism values.
