    New laser system simplifies astigmatism correction

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

     

    Once the incisions are made, Dr. Jackson said that he generally leaves them closed and has patients return after three to four weeks for evaluation of their refractive outcome. Then, with the patient sitting in an exam lane at the slit-lamp, he can titrate the astigmatic effect as needed by opening the incisions.

    “It is easy to do with a Sinskey hook or similar microsurgical instrument,” he said.

    As an exception, the astigmatic incisions are opened intraoperatively in cases where intraoperative aberrometry is used (ORA, Alcon) and can determine if additional deepening and/or lengthening of the astigmatic incisions are needed.

    Using the LENSAR laser, Dr. Jackson said that many surgeons treat up to 1.5 D of corneal astigmatism. He, however, is stretching his upper limit to 1.7 D with these techniques.

    With the added range and increased predictability compared with manual incisions, Dr. Jackson said he is now using the laser to correct astigmatism in more eyes where he otherwise would have implanted a toric IOL.

    “This shift reduces overhead and so helps enhance my bottom line,” Dr. Jackson said.
