This is a sole source procurement for three vitrectomy machines for the Ophthalmology department, with services to be performed at the Battle Creek VA Medical Center in Battle Creek, MI in support of the Ann Arbor VA Medical Center. The delivery timeline is anticipated to be one month from receipt of order. The justification states that only one responsible source, OR Elder, can meet the agency's requirements for this specific Alcon Unity VCS system, as it is a combined anterior and posterior segment machine with unique technology not offered by competitors. The absence of a working backup machine creates patient safety and access concerns for veterans. Market research confirmed no other sources for this specific equipment.
