    Area of Science:

    • Ophthalmology
    • Surgical Devices
    • Ophthalmic Surgery

    Background:

    • Cataract surgery and management of secondary membranes and persistent hyperplastic primary vitreous present surgical challenges.
    • The Roto-Extractor is a novel device designed to address these challenges in ophthalmic procedures.

    Purpose of the Study:

    • To evaluate the efficacy and safety of the Roto-Extractor in treating various ocular conditions.
    • To assess the complication profile associated with the use of the Roto-Extractor.

    Main Methods:

    • The Roto-Extractor was utilized in 66 eyes across a cohort of patients undergoing surgery for cataracts, secondary membranes, and persistent hyperplastic primary vitreous.
    • Patient demographics included average ages of 2.4 years for congenital cataracts and 16.4 years for traumatic cataracts.

    Main Results:

    • The device was used in 66 eyes for conditions including cataracts, secondary membranes, and persistent hyperplastic primary vitreous.
    • Pupillary clearing was successful in 63 of the treated eyes.
    • No instances of vitreous prolapse into the surgical wound were observed.

    Conclusions:

    • The Roto-Extractor demonstrates utility in managing cataracts and related ophthalmic conditions.
    • While generally effective, potential complications include unplanned iridectomies and prolonged inflammation, necessitating careful surgical consideration.
