    Transzonular approach to antibiotic delivery during cataract surgery is preferable

    Delivery of medications at time of surgery better for cornea, eliminates compliance concerns


    4 Cs outlined

    First, a transzonular approach does not impact the tear film and cornea, which are often compromised in cataract surgery patients. In contrast, topical drops can exacerbate ocular surface irritation.

    Second, compliance is no longer an issue when medications are delivered via a transzonular approach. “So many patients are not compliant despite the schedules we give them,” Dr. Matossian pointed out.

    Patients may forget, get confused, or they are physically challenged. For example, a patient with rheumatoid arthritis or tremors may have trouble instilling drops.

    Medication cost is the third issue among Dr. Matossian’s four Cs. “The cost of medications has gone up so much, and fewer and fewer insurances are covering them,” she added.

    This, in turn, leads to callbacks to the office, which consume staff time and tie up phone lines. Moreover, patients prescribed topical drops for cataract surgery call the practice confused because their pharmacist has substituted a generic drug with a different dosing schedule than their original script from our practice.

    With the transzonular administration of medications, compliance is no longer an issue, and the concern over cost is lower.
