    Pearls for transzonular approach

    Dr. Matossian shares a few pearls about using a transzonular approach.

    First, a transzonular approach is not difficult, although there is a manageable learning curve, Dr. Matossian said.

    “You need an angled cannula to get through the zonules,” she added. “Because it’s a blind maneuver where you are pushing very gently to the bend of the cannula, you could bump the ciliary body and cause transient discomfort. You could also cause a little bleeding. Potentially, the intraocular lens could get temporarily vaulted forward from the volume change.

    However, Dr. Matossian has several pearls to better manage the transzonular approach.

    “I remove some of the ophthalmic viscosurgical device before I do a transzonular injection,” Dr. Matossian said. She also will warn patients that on the evening of their surgery day, they may notice floaters. “This forewarning can prevent call backs,” she pointed out.

    Dr. Matossian encourages surgeons interested in the transzonular approach to call colleagues, watch videos, or visit surgeons who are using it to see if it is right for them.
