Contact Lens & Vision Associates 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 an 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 for tool for contact lens fitting in diagnosing astigmatism and measuring the shape of unusual corneas for proper lens shape. Very helpful for diagnosis patients with dry eyes and front of the eye swelling.

Digital Retinal Photography: A digital camera used to photograph the retina and optic nerve to document health status in a patient; images are printed or shown to the patient on a monitor. Used for diagnosis of glaucoma and retinal problems such as acular degeneration and diabetic eye disease.

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.
