This instrument is the 23 gauge version of the popular 20 gauge Lewicky Anterior Chamber Maintainer. It provides control over the depth of the anterior chamber during eye surgical procedures where anterior chamber depth control is important, including cataract surgery, IOL surgery, hyphema evacuation and IOL manipulations and relocations. The 23 gauge shaft is designed for easy insertion through most side port incisions without any need for enlargement. The self-retaining threaded tip assures stable fixation within the corneal stroma.
