State-Of-The-Art Vision Services and Equipment

Armstrong-Root is committed to providing the optimal services with the state-of-art EIDON try color confocal scanning ophthalmoscope. Say goodbye to getting your eyes dilated, with the Eidon Dr. Kent is able to look inside the eye. "We have the only EIDON diagnostic equipment available in Idaho, Wyoming, and Montana," says owner, Laurrine McGowen.

The diagnostics component is a tremendous acquisition for the store, as it offers an unprecedented level of diagnostic accuracy. This device provides true color, high-resolution imaging of the retina with great contrast than a traditional diagnostic camera can achieve. Because the scanner uses white light instead of monochromatic lasers to obtain an image, the retina appears as it actually looks in true color, allowing doctors to make more accurate diagnoses and observations. No dilation of the pupil is required to obtain high-resolution images, and exam time per eye generally stands as one minute or less. The scanner allows for imagining in infrared and red-free modes as well, enhancing the visibility of the retinal vascular and nerve fibers. Unlike traditional imaging equipment, the scanner can penetrate dense cataracts and is especially beneficial for treating patients with serious vision and optical problems such as glaucoma, macular degeneration, sudden vision loss, and diabetic retinopathy.     



The medical staff includes Dr. Matthew Kent, as well as three certified opticians and a national certified contact lens examiner. To make an appointment to see Dr. Kent please call 208-726-4250 or email
