Icare® Tonometer
Icare® tonometer for quick, easy and painless eye pressure measurement by Ophthalmologies, Optometrists, Opticians, General Practitioners & Pharmacies – without anesthesia or air.
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 and often does not even cause corneal reflex. 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).
The easy usage and dynamic patient flow obtained by the Icare® tonometer make it a very important instrument for general practitioners, optometrists, occupational health care, pharmacies and other medical personnel.
Requiring no drops, nor specialized skills for its use the quick and painless Icare® tonometer makes IOP measuring easy and has an important role in glaucoma screening programs of masses.
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 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 you are concentrating.
Each eye is tested separately and the entire test takes 15-45 minutes. Your optometrist may ask only for a driving licence visual field test, which takes 5-10 minutes. If you have just asked for a driving test or the clinic doctor advised you have one, you will be informed of the result by the clinic doctor, in writing, in a few weeks.
Normally the test is carried out by a computerised machine, called a Humphrey. Occasionally the manual test has to be used, a Goldman. For each test you have to look at a central point then press a buzzer each time you see the light.
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.
The optomap® Retinal Exam is fast, easy, and comfortable for all ages. To have the exam, you simply look into the device one eye at a time and you will see a comfortable flash of light to let you know the image of your retina has been taken. The optomap® image is shown immediately on a computer screen so we can review it with you.

Daytona Optomap Retinal Imaging Camera
The Optos Daytona is a scanning retinal imaging instrument that is able to take ultra-wide images of a patient’s retina. Typically the size of the pupil will limit any imaging system or camera from seeing many parts of the internal lining of the patient’s eye called the retina. The Optos Daytona uses special technology in Commerce City, CO to capture retinal images as if it were taking them from inside the eye.
How much of the retina, does the Optos Daytona look at and give imaging for?
Most cameras that image the retina without pupil dilation can image about 60 degrees. The Optos Daytona is able to show our doctors roughly 270 degrees of a patient’s retina without the use of dilating drops. Most cameras can capture an area of the retina known as the posterior pole (that include the macula and optic nerve head), but it is only with the Daytona imaging system that we are able to see much more of the peripheral retina.
What types of eye diseases and disorders can be discovered?
The Optos Daytona helps our doctors to diagnose eye diseases such as glaucoma, macular degeneration and diabetic retinopathy. We are able to monitor “freckles” in the back of the eye known as a choroidal nevus. We’ve discovered retinal melanomas and peripheral abnormalities such as retinal holes, retinal tears and retinal detachments. It can also sometimes help us to see vitreal floaters. It also allows us to monitor patients on a drug called Plaquenil that is often used in rheumatoid arthritis and can cause retinotoxicity.
What is it about this particular technology that is most exciting; the component that made us feel the need to invest in this for our practice?
The “wow factor” from our patients has continued for over a decade. 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.
What is the patient experience when using the Optos Daytona?
The new Daytona model is even more user friendly than it’s predecessor the P-200. It is a smaller machine and patients are more easily able to position themselves in the instrument with some light cues indicating if they are not in the correct position. It’s quick and totally painless.
The Optos Daytona improves comprehensive eye exams compared to the days it was not available in the optometric office. At North Range Eye Care, our ability to view more of the retina during a routine eye exam is the key component. We are always able to look into an eye without the Optos Daytona, but the ability to get an overall view and share the results with the patient is truly amazing. We feel that it is important to point out that this doesn’t replace a dilated fundus exam, but if our doctors do image an area that needs a better look then drops will be used to dilate the pupil and get another view with other technology. The same goes for those patients who present with complaints that are most likely retinal in nature, we still like to use the Daytona for imaging, but we will also dilate the pupils to get an ever wider angle view.
What patients are recommended to use the Optos Daytona?
This imaging system is included with all of our comprehensive eye exams other than those for children (18 years and younger). We advise having children imaged at least every 3 years.
