Technology – Advanced Eye Care

We use the most up-to-date technology to ensure the best eye care possible. Here are some of the different types of tests and equipment you may experience on a visit to our Practice.

Corneal Mapping

Corneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye. Since the cornea is normally responsible for some 70% of the eye's refractive power, its topography is of critical importance in determining the quality of vision.

The three-dimensional map is therefore a valuable aid to the examining ophthalmologist or optometrist and can assist in the diagnosis and treatment of a number of conditions; in planning refractive surgery such as LASIK and evaluation of its results; or in assessing the fit of contact lenses. A development of keratoscopy, corneal topography extends the measurement range from the four points a few millimeters apart that is offered by keratometry to a grid of thousands of points covering the entire cornea. The procedure is carried out in seconds and is completely painless.

Digital Retinal Imaging & OCT Scans

We use cutting-edge digital imaging technology to assess your eyes. Many eye diseases, if detected at an early stage, can be treated successfully without total loss of vision. Your retinal Images will be stored electronically. This gives the eye doctor a permanent record of the condition and state of your retina.

This is very important in assisting your Optometrist to detect and measure any changes to your retina each time you get your eyes examined, as many eye conditions, such as glaucoma, diabetic retinopathy and macular degeneration are diagnosed by detecting changes over time.

The advantages of digital imaging include:

  • Quick, safe, non-invasive and painless
  • Provides detailed images of your retina and sub-surface of your eyes
  • Provides instant, direct imaging of the form and structure of eye tissue
  • Image resolution is extremely high quality
  • Uses eye-safe near-infra-red light
  • No patient prep required

Digital Retinal Imaging

Digital Retinal Imaging allows your eye doctor to evaluate the health of the back of your eye, the retina. It is critical to confirm the health of the retina, optic nerve and other retinal structures. The digital camera snaps a high-resolution digital picture of your retina. This picture clearly shows the health of your eyes and is used as a baseline to track any changes in your eyes in future eye examinations.

Optical Coherence Tomography (OCT)

An Optical Coherence Tomography scan (commonly referred to as an OCT scan) is the latest advancement in imaging technology. Similar to ultrasound, this diagnostic technique employs light rather than sound waves to achieve higher resolution pictures of the structural layers of the back of the eye.

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.

With an OCT scan, doctors are provided with color-coded, cross-sectional images of the retina. These detailed images are revolutionizing early detection and treatment of eye conditions such as wet and dry age-related macular degeneration, glaucoma, retinal detachment and diabetic retinopathy.

An OCT scan is a noninvasive, painless test. It is performed in about 10 minutes right in our office. Feel free to contact our office to inquire about an OCT at your next appointment.

Visual Field Testing

A visual field test measures the range of your peripheral or “side” vision to assess whether you have any blind spots (scotomas), peripheral vision loss or visual field abnormalities. It is a straightforward and painless test that does not involve eye drops but does involve the patient's ability to understand and follow instructions.

An initial visual field screening can be carried out by the optometrist by asking you to keep your gaze fixed on a central object, covering one eye and having you describe what you see at the periphery of your field of view. For a more comprehensive assessment, special equipment might be used to test your visual field. In one such test, you place your chin on a chin rest and look ahead. Lights are flashed on, and you have to press a button whenever you see the light. The lights are bright or dim at different stages of the test. Some of the flashes are purely to check you are concentrating. Each eye is tested separately and the entire test takes 15-45 minutes. These machines can create a computerized map out your visual field to identify if and where you have any deficiencies.

Optovue- iVue OCT

Optovue Ivue OCT

We are proud to offer the Optovue- iVue OCT. The iVue is a comprehensive OCT platform that allows us to have retinal, optic nerve and anterior segment imaging capabilities, as well as the exclusive iWellness scan. This quick and easy scan provides an in-depth look at the health of your retina and other portions of the inner eye, which helps us identify signs of disease before they would be noticed on an eye exam which did not include this in-depth eye scan.

We are proud to use the Medmont E300 Corneal Topographer, a computerized video-keratometer, in our office.

A-Scan & B-Scan Ultrasonography

AB ScanA-Scan and B-Scan are terrific Ophthalmic ultrasonography technologies offered by our New York office. A&B Scans use high-frequency sound waves, which are transmitted from a probe placed on the eye. As the sound waves strike intraocular structures, they are reflected back to the probe and converted into an electric signal. The signal is subsequently reconstructed as an image on a monitor, which can be used to make a dynamic evaluation of the eye or can be photographed to document pathology.

A-Scans A-Scans provide data on the length of the eye, which is a major determinant in common sight disorders. The most common use of the A-scan is to determine eye length for calculation of intraocular lens power to be inserted during cataract surgery.

B-Scans are an important adjuvant for the clinical assessment of various ocular and orbital diseases. It is most useful when direct visualization of intraocular structures is difficult or impossible. Situations that prevent normal examination include lid problems, dense cataracts, corneal scars, and vitreous opacities or hemorrhages. In such cases, diagnostic B-scan ultrasound can accurately image intraocular structures and give valuable information on the internal structures of the eye. However, in many instances, ultrasound is used for diagnostic purposes even though pathology is clinically visible to better differentiate the pathology.

Autorefractor (general)

trs 5100

The auto-refractor is a digital refractor that works much the same way as the old fashioned phoropter. The big difference is that, instead of the doctor manually clicking through, asking you to decide for yourself which lens is best (which is especially hard when the lenses are very nearly the same!), the auto-phoropter is controlled electronically and measurements are done digitally. This not only shortens the amount of time it takes to decide which lenses will provide you your best vision correction (super helpful when trying to get your little one to stop squirming and co-operate with the process!), but also ultimately results in a more accurate eyeglass or contact lens prescription.

Anterior segment imaging

While there are many digital cameras available, often an anterior segment camera can provide a digital photograph of the eye with the proper color, contrast, sensitivity, and resolution easily by an eye doctor. By getting a clear image of the front of the eye, this information can help diagnose irregularities with the cornea, misalignments, and various eye conditions or damage that may affect your eyes on an external level.Anterior segment imaging
