Study summary

To determine patient preference for the dexamethasone insert or topical prednisolone therapy through at Day 45 as measured by - Modified COMTOL survey.

Read the detailed description

Eyes from 80 patients will be randomized in a 1:1 ratio to the assigned treatment, dexamethasone insert placed at the time of surgery, or topical prednisolone acetate 1% therapy prescribed on a tapering dose schedule post-operatively.

Males and Females 18 years and older with 1)Presence of a visually significant cataract with plans to undergo clear cornea cataract surgery with phacoemulsification and implantation of a posterior chamber intraocular lens (IOL), and potential postoperative Snellen pinhole corrected distance visual acuity (CDVA) of at least 20/200 in both eyes and 2) 10 patients with mild-to-moderate primary open angle glaucoma and a visually significant cataract with plans to undergo clear cornea cataract surgery with phacoemulsification and implantation of a posterior chamber Intraocular Len (IOL) combined with a Minimally Invasive Glaucoma Surgery (MIGS) procedure in both eyes.

Study visits will consist of eye exam with ocular photos from an Optical Coherence Tomography (OCT).

Study arms

  • Other
    DEXTENZA vs prednisolone acetate 1%)

    Subjects will randomly receive Dextenza or prednisolone acetate 1% in the first eye after surgery. At the time of the second eye surgery, the other eye will receive the drug that the first eye did not receive. Subjects will receive both drugs during the course of the study and therefore there is only 1 ARM for this study.

    Drug: Dextenza 0.4Mg Ophthalmic Insert · Drug: Prednisolone Acetate 1% Ophthalmic Suspension [PRED FORTE]

Interventions

  • DrugDextenza 0.4Mg Ophthalmic Insert

    The eye will have a sustained release device of Dexamethasone 0.4 mg placed in the inferior nasal lacrimal system.

  • DrugPrednisolone Acetate 1% Ophthalmic Suspension [PRED FORTE]

    The eye will be randomized to receive topical treatment with prednisolone acetate 1% on a tapering dose schedule
