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. We have Optovue OCT technology in our office.

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.

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.

OPTOS Retinal Exam

Annual eye exams are vital to maintaining your vision and overall health. We offer the optomap® Retinal Exam as an important part of our eye exams. The optomap® Retinal Exam produces an image that is as unique as you fingerprint and provides us with a wide view to look at the health of your retina. The retina is the part of your eye that captures the image of what you are looking at, similar to film in a camera.

Many eye problems can develop without you knowing. You may not even notice any change in your sight. But, diseases such as macular degeneration, glaucoma, retinal tears or detachments, and other health problems such as diabetes and high blood pressure can be seen with a thorough exam of the retina.

An optomap® Retinal Exam provides:

  • A scan to show a healthy eye or detect disease.
  • A view of the retina, giving your doctor a more detailed view than he/she can get by other means.
  • The opportunity for you to view and discuss the optomap® image of your eye with your doctor at the time of your exam.
  • A permanent record for your file, which allows us to view your images each year to look for changes.

Daytona Optomap – Retinal Imaging

For many eyecare patients, having pupils dilated (opened up) using eye drops can be a bother. But as an integral part of a truly comprehensive eye exam, those drops are highly recommended. Dilation gives your eye doctor the widest view of the internal structures at the back of the eye—the optic nerve, retina, even blood vessels.

That’s where Optomap technology comes in. Using low-power laser technology, your eye care professional can take a wide, instantly-viewable and detailed digital scan of your retina (the area responsible for processing images). All in real time. And in no time. Without the use of pupil-dilating eye drops.

How does Optomap work?

It’s very similar to sitting down in a type of photo booth and leaning forward to have your picture taken. Except in this instance, the picture being taken is a larger, wide-field image of the inside of your eyeball. Optomap takes around a minute.

Daytona is smaller and still provides ultra-high resolution imaging, and adding ultra-widefield autofluorescence capabilities. This device can take around a 200-degree image of the retina in one image. Most cameras can only capture the posterior pole (that include the macula and optic nerve head), but the Daytona can view the peripheral retina as well.

Patients find this device very exciting. To be able to easily image a patient’s retina and then be able to review it with them in the exam room is a great educational tool and a valuable way of comparing changes over time.

Since retina scanning is so important in the early detection of cataracts, diabetic eye disease, glaucoma, age-related macular degeneration and more, it’s pretty easy to see why Optomap technology is so promising.

Optomap retinal exams are not available everywhere, however. And in some instances, these scans may not be covered by traditional insurance due to cuts in eye doctor reimbursements.

Check with your eye care professional and ask if an Optomap eye exam is right for you.

Marco Xfraction – Auto-Refraction system with Wavefront Aberrometry

Specifically, XFRACTION is an industry shaping process that optimizes refraction (and all the downstream benefits of enhanced refractive diagnostics), with the addition of the most advanced wavefront technology available. At its core, XFRACTION provides the most comprehensive picture of the total visual system (in a fraction of the time), and a rapid diagnostic triage process for physicians.

DIAGNOSTIC DISCERNMENT – KNOWLEDGE

The OPD­-Scan III wavefront aberrometer/corneal analyzer projects over 2500 light vectors through the widest optical pathway, to map out the complete visual system. Minimal extrapolation translates into more real, accurate, and usable information – unique to each patient. In 10 seconds, over 20 diagnostic measures are determined. In less than a minute, the OPD allows rapid discernment between patients who will require minimal refinement or a full refraction to achieve 20/20. More importantly, this instrument can determine which patients cannot correct to 20/20…and optically why not.

PRACTICE EFFICIENCIES – SPEED

The refractive starting point as determined by the OPD Scan III is automatically transferred to the TRS-­5100 digital refractor – where either minor refinements or full digital refractions are completed. The TRS system provides unparalleled accuracy, repeatability, speed, and efficiency in completing any refraction, in the hands of any operator. Patient verification of the result and professional validation remains an integral part of the examination process. Immediate comparison of old vs. new Rx assures patients of the value of the prescribed change. Time saved in waiting and testing is reinvested in quality time utilization, enhanced patient experience, and practice productivity.

OPTIMIZED OUTCOMES – IMPACT (on the Patient Experience and Practice Profitability)

Practices benefit from the XFRACTION process in numerous, significant ways. Improved analytics and faster exam times translate to more reliable diagnostic and surgical outcomes and expanded capacity, respectively. By determining the best optical Rx, reducing remakes, and providing superior IOL selection to optimize the surgical outcomes, positive cash flow and overall profitability are improved. Patients experience real satisfaction and confidence in the quality of each visit. They are partnered within their examination process, their understanding of their conditions, and results. The elevated patient experience can be directly measured by patient loyalty and referrals.

iCare Tonometers

icare tonometeriCare 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 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).
