    Improving the accuracy and comfort of intravitreal injections

    Mainstay treatment requires accurate positioning, depth and angle of the injection needle


    Addressing the discomfort of the procedure

    Despite the fact that the use of both a surgical drape and speculum are advised to lower the risk of infection during injections, studies have shown that this sterile procedure can have a negative impact on the patient’s perception of the treatment. In one study, 53% of patients indicated that placement of the drape caused feelings of claustrophobia and anxiety, plus the use of a speculum accounted for a high level of stress, second only to the pain during needle insertion.1,2

    To address these issues, I decided to see if I could come up with a better solution. This, in collaboration with the innovation panel at Plymouth Hospitals NHS Trust, led to the development of an intravitreal injection guide (IVT; Malosa Medical/Beaver-Visitec International), a device which eliminates the need for a surgical drape and speculum during the IVT injection procedure, largely due to a built-in lash guard.

    In addition, the cylindrical chamber of the injection guide is designed for use with a 30-gauge needle to improve patient tolerance and reduce the pain patients feel during needle insertion.
