Advanced Technology


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 eyeglasses or contact lens prescription

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.

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

Digital Retinal Imaging

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 our optometrists 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 preparation required

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.

OPTOS Daytona Optomap Retinal Scan

We are proud to introduce the latest cutting edge technology in retinal imaging, the Optos Daytona Optomap OCT. This amazing device allows your eye doctor to see retinal, optic nerve and cornea structures not visible through regular exam methods by using light to provide a high resolution scan meant to pick up early signs of structural change or disease. Your eye doctor will see even the smallest changes in the retina and optic nerve with greater accuracy, and much higher definition, making early and accurate detection of common sight threatening eye conditions such as glaucoma, macular degeneration and diabetic retinopathy, easier than ever before. While traditional imaging technologies are usually able to scan around 15% of your retina at a time, The OPTOS Optomap is able to scan in a stunningly large 200 degree arc, capturing about 80% of your retina in one panoramic scan. This allows for a wider and more accurate view of the retina than with less advanced scans. This scan will provide you and your eye doctor with an extremely detailed picture of your eye that will act as a valuable road map of your overall eye health. The high resolution images produced by the Optos Daytona Optomap OCT provide a personal benchmark for each person’s ocular health and helps detect sudden changes through the years, and since the images show up automatically on a computer monitor, you are able to see for yourself everything the doctor is telling you about your eye health, allowing you to take an active role in preserving your valuable sense of sight. The patient experience is also fast, easy and painless. Nothing touches your eye at any time and it is suitable for the whole family, from youngest to oldest. The exam consists of taking a brief look into the device one eye at a time. You will see a comfortable flash of light, which lets you know the image of your retina has been taken, and you’re done!

Fundus Camera

A fundus, or retinal camera, is a specialized microscope with an attached camera designed to photograph the central retina, optic disc and macula.The resulting photograph is a high resolution magnified image which can help to assess for eye conditions including glaucoma, diabetic retinopathy, macular degeneration, optic nerve disease, and many others. This picture also gives us a baseline to compare the state of your eye health in the future.

Zeiss VISUCAM 524 fundus camera

We are proud to use the Zeiss VISUCAM 524 fundus camera, with a 24-megapixel sensor, in our eyecare office.

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, optometrists 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.


We are proud to use the Cirrus HD-OCT system in our optometry office.


We are proud to use the Cirrus HD-OCT 5000 system, featuring a modernized system based on a faster processing system, in our eyecare office.


A tonometer is used to measure intraocular pressure (IOP), which is the pressure inside your eye. A tonometry test is primarily used to check for glaucoma, which is a serious eye disease that can lead to blindness if not treated properly. There are several types of tonometers, including a non-contact tonometer that uses air and does not require eye drops. No matter which type of tonometer your eye doctor uses, the test is painless.

Air Puff Tonometer

A non-contact tonometer (also knows as a “puff test”) measures the pressure in the eye. This is an important test for glaucoma screening, which is a serious eye disease that can lead to blindness if not treated. The puff of air measures the pressure in the eye by flattening the cornea in a non-invasive manner.

iCare Tonometer

iCare Tonometers are used for easy, accurate and patient-friendly intra-ocular pressure measurement, which is used for glaucoma screening. iCare tonometers are based on unique, patented rebound technology, in which a very light and small probe is used to make a momentary contact with the cornea. The Icare tonometer is based on a proven accurate measuring principle, in which a very light probe is used to make momentary and gentle contact with the cornea. The measurement is barely noticed by the patient. The device not only makes IOP measuring a more pleasant experience on all patients, it is also an important break-through for succeeding with non-compliant patients (i.e. children and dementia patients).

Visual Field Test

A visual field test measures how much ‘side’ vision you have. It is a straightforward test, painless, and does not involve eye drops. Essentially lights are flashed on, and you have to press a button whenever you see the light. Your head is kept still and you have to place your chin on a chin rest. The lights are bright or dim at different stages of the test. Some of the flashes are purely to check if you are concentrating. Each eye is tested separately and the entire test takes 6-15 minutes. Normally the test is carried out by a computerized instrument, called a Humphrey Visual Field Analyzer. Visual Field testing can help detect eye conditions such as glaucoma, migraines, multiple sclerosis, and neurological conditions such as brain tumors and aneurysms.

Humphrey Field Analyzer 3

Our office is proud to use the Humphrey Field Analyzer 3 (HFA3) from ZEISS, in our optometry office.

LipiView and LipiFlow

TearScience produces the LipiFlow® and LipiView® devices for treating Meibomian gland dysfunction (MGD). The LipiView® provides a detailed view of the tear film using interferometry which permits precise measurement of lipid layer thickness down to nanometer levels. The LipiFlow® device provides vectored thermal pulsation to warm the meibomian glands through the inside of the lids and gently massage thickened meibum (lipid) and debris from the gland. This system is cleared by the US FDA for the treatment of MGD and evaporative dry eye. With hundreds of patients successfully treated, LipiFlow® has proven to be safe and effective.

Ocular Response Analyzer

Corneal Hysteresis Testing by the Ocular Response Analyzer: The ocular response analyzer uses a rapid are impulse to measure the difference between two pressure measurements, the pressure of the cornea moving inward minus the pressure of the cornea returning to its normal shape. This difference is known as corneal hysteresis, and is a powerful tool in glaucoma evaluation. A number between eight and fourteen is considered normal. Numbers between five and eight are borderline, whole numbers less than five are considered abnormal.

Maculogix AdaptDX® Dark Adaptometer

Backed by more than 20 years of clinical research, AdaptDx® delivers objective results with a non-invasive assessment that’s easy to administer. Dark adaptation function, the recovery of vision when going from daylight to darkness, is the only biomarker of age-related macular degeneration (AMD). AdaptDx® provides a practical and objective way to measure dark adaptation with a test that can be completed in just a few minutes. Early detection and monitoring can prevent unnecessary vision loss by facilitating interventions at the earliest possible stages. The test is non-invasive. It’s conducted in a darkened room with the patient’s chin and forehead resting on comfortable supports similar to those on other eye care instruments. The experience is similar to routine perimetry for glaucoma testing and it takes about the same amount of time.

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.

Huvitz Wavefront Aberometer

Aberrometry measures the way a wavefront of light passes through the cornea and the crystalline lens, which are the refractive (light focusing) components of the eye. Distortions that occur as light travels through the eye are called aberrations, representing specific vision errors. Wavefront technology, or aberrometry, diagnoses both lower- and higher-order vision errors represented by the way the eye refracts or focuses light.

B-scan ultrasonography

B-scan ultrasonography: A non-invasive diagnostic procedure that gives us a two dimensional image of the eye’s interior structures. This scan is used on the outside of a closed eye when it is difficult to view the eye normally. The B-scan allows us to diagnose potential tumors in the eye and other eye diseases.

Nidek OPD-Scan III Wavefront Analyzer

The unique OPD-Scan III is an advanced vision-assessment system that combines topography, wavefront, autorefraction, keratometry, and pupillometry — allowing accurate and reliable analysis of corneal aberration.

Optometric Slit Lamps (Slit Lamp Biomicroscopes)

The slit-lamp exam allows the doctor to see areas at the front of the eye. These areas include your eyelids, conjunctiva, iris, lens, sclera and your cornea. Other areas visible with the slit-lamp test are the retina and optic nerve. Optometrists use slit lamps to identify disorders, infection or any other complications offering a more interactive approach to documenting an eye exam.

Vivid Vision

Built for the Oculus Rift, HTC Vive, and Samsung GearVR and supporting 3D gesture control with the Leap Motion, Vivid Vision for Amblyopia is a totally immersive virtual reality experience designed for people who have Amblyopia, Strabismus (lazy eye) and Convergence Insufficiency. Vivid Vision increases visual stimulation to the patient’s weak eye, and decreases stimulation in the stonger eye, using VR games. In these special games, the patient sees game cues in their weaker eye, thus causing the brain to rely more on the weaker eye than it normally does.


Readalyzer is a diagnostic tool that uses infrared technology to record eye movements while a patient is reading age appropriate reading materials. Your doctor uses the Readalyzer to diagnose problems you may be having with reading comprehension, in addition to eye tracking and teaming dysfunctions.

Computerized Corneal Topography

Computerized Corneal Topography gives accurate mapping of the corneal curvature. It is a computerized Video-Keratometer, that maps the surface of your cornea. What this map reveals is the topography, or shape of the corneal surface. The Corneal Topography assist in contact lens fitting, refractive surgery, orthokeratology and general assessment of the cornea. Corneal maps can also detect changes in corneal shape from office visit to office visit, which is extremely helpful in keratoconus. Maps can even be sent over the Internet to contact lens manufacturers who are customizing lenses, or to other doctors for second opinions. It supports many important optometric applications, including contact lens fitting, pathology detection and management.


ColorDx: A detailed color vision evaluation that determines if there is loss of color perception as a result of optic nerve head disease, diabetic eye disease or other neurological eye disease. Tritan deficiencies (blue color vision defects) are rarely genetic, yet as high as 15% of the general population may have a tritan deficiency. This is an important but often overlooked sign that may be caused by retinal, optic nerve, or neurological disorders, in addition to trauma, cataracts, and hundreds of common drugs and substances.

Available exclusively at or next to LensCrafters.


An important step in treating meibomian gland dysfunction is debriding – or removing the excessive buildup of cells, debris and biofilm from the area around the meibomian glands – called Marx’s line. Blephex helps unblock the glands. The recently introduced BlephEx device is a gentle but extremely effective way of debriding the lid margins. This procedure is typically done every six months.

BRUDER Moist Heat Eye Compress

Our BRUDER Moist Heat Eye Compress opens oil glands and allows natural oils to flow back into the eye relieving discomfort from aging, contact lenses, use of digital devices and more. The easy-to-use compress delivers an effective moist heat treatment. Simply microwave for 20-25 seconds and apply for 10 minutes or as prescribed by your doctor. The compress helps stabilize the tear film, improves oil gland function and slows tear evaporation. Properly hydrated and lubricated eyes can expel bacteria and debris more efficiently so your eyes will feel refreshed and rejuvenated.

TearLab Osmolarity System

Tear osmolarity has been shown to have the best predictive value for diagnosing Dry Eye Disease of any single test. TearLab’s sophisticated lab on a chip technology tests a tiny tear sample to measure Osmolarity, or the salt content in the tears. The Doctor will test both eyes, and will take the highest number of the two tests, to generate Your Osmolarity Number. Your Osmolarity Number gives doctors a meaningful measure of the health and stability of the protective tear film that covers the surface of your eyes. The number generated correlates with the severity of the disease.

Meibox Meibographer

The Meibox Meibographer is the first HD slit lamp mounted meibographer designed for doctors by doctors. This diagnostic tool helps doctors determine if all the patient’s meibomian glands are functioning by using Meibox, a meibography imaging test which illuminates the glands with a non-invasive Infra-red light. Providing high resolution images of meibomian glands, the Meibox has helped take the mystery out of dry eyes.
