    Area of Science:

    • Ophthalmology
    • Surgical Instrumentation

    Background:

    • Radial keratotomy requires precise corneal incisions for effective refractive correction.
    • Maintaining ocular stability and controlled intraocular pressure is crucial during the procedure.

    Purpose of the Study:

    • To introduce and describe the Vacuum Fixation Ring as a device for enhancing radial keratotomy.
