Contact Lens & Vision uses state-of-the-art technology to ensure that our patients receive the very best care. Below are some of the diagnostic instruments we use to detect and monitor eye disease and/or to precisely correct your vision.
Optical Coherence Tomography (OCT): A scanning laser used to analyze the layers of the retina and optic nerve for any signs of eye disease, similar to a CT scan of the eye. It works using light without radiation, and is essential for early diagnosis of glaucoma, macular degeneration and diabetic retinal disease.
Specular Microscope: An instrument that takes a picture of the cornea (front of the eye) and analyzes the innermost layer for swelling or disease. Important for contact lens wearers, elderly and post-surgical patients, and for patients with redness or infection. It help determine prognosis regarding cataract surgery and future contact lens wear.
Corneal Topographer: An instrument used to measure the curvature and overall shape of an eyeball. It's an important tool for contact lens fitting, in diagnosing astigmatism, and measuring the shape of unusual corneas for proper lens shape.
It is very helpful for diagnosing patients with dry eyes and front of the eye swelling.
Digital Retinal Photography: This instrument is a digital camera that is used to photograph the retina and optic nerve (located in the back of the eye) to document the health of patient's eye. These images are printed or shown to the patient on a monitor and are used for diagnosis of glaucoma, macular degeneration, diabetic eye disease, high blood pressure related disease, and other retinal diseases originated
from systemic conditions.
Visual Field Analyzer: This measures a patient's peripheral (side) vision by illuminating a series of small lights around your field of vision while you stare
straight ahead. It documents any loss or change in peripheral vision status due to eye disease, central nervous disorder, or genetic disorder. Used to aid in the diagnosis of glaucoma.
B-scan: A hand-held instrument used to perform an ultrasound to document size
and elevation of any growths or lesions in the eye.
Pachmate Pachymeter: This diagnostic tool is used to measure the thickness of
the cornea (front of the eye) and helps in the diagnosis of glaucoma, as well as determining how accurate the "puff of air" test is for patients with high ocular pressure.

PHP is a specialized macular perimeter for long term monitoring of dry age-related macular degeneration (AMD) patients and early detection of wet AMD or choroidal neovascularization. This new technology uses preferential hyperacuity perimetry to identify central visual field defects associated with AMD and compares patient responses to an extensive database of wet and dry AMD patients. This analysis can indicate conversion to wet AMD at an early stage, when treatment offers the potentially best visual outcome for the patient. It is a simple, quick, non-invasive test that could potentially reduce vision loss as a result of AMD.

Visual Evoked Potential (VEP) designed to objectively measure the functional responses of the entire visual pathway from the anterior segment of the eye to the visual cortex. This non-invasive procedure detects abnormalites that are subtle and difficult to detect in an objective manner. No verbal response is required which assists in diagnosis of preverbal children, infants and those with communicative challenges.

QuantifEYE measures the relative health of your macula. Your eye care professional can now better determine your risk for Age Related Macular Degeneration (AMD) simply by determining other risk factors and getting your MPOD measurement. Prior to this exam, you will be asked questions to assess what other risk factors you may have that can be associated with developing AMD. The test using the QuantifEYE device is simple, quick, non-invasive, and does not require dilation prior to examination. A base-line measurement is taken, and the results are your MPOD score. If you happen to test low (low MPOD scores = increased risk for AMD) to medium, your eye care professional may recommend supplementation to restore depleted levels of zeaxanthin, meso-zeaxanthin and lutein in your macula. (With MPOD testing and supplemental intervention, it is possible to increase the pigment levels in your macula, thus lowering your risk for vision loss.) Your eye care professional will then be able to determine through follow up screenings if nutritional intervention is resulting in increased macular pigment. Ask for this important test today. It's not too early to take steps to preserve your vision and restore your eyes to a healthier state.
