Digital Retinal Imaging
We use cutting-edge digital imaging technology to assess your eyes, which allows the doctor to evaluate the health of the back of the eye, the retina. 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 the doctors at 20/20 Vision Center 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. Retinal imaging is a quick, safe, non-invasive and painless procedure that takes only seconds to perform, and provides instant high resolution digital images.
Corneal topography 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 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. Corneal Topography measures thousands of points on the cornea, providing detailed information about it’s shape. The procedure is carried out in seconds and is completely painless.

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. We include the highly advanced Humphrey Field Analyzer in our high-tech lineup because it is the accepted standard of care in glaucoma diagnosis and management.
If during your comprehensive examination other tests or symptoms indicate a possible problem, the doctors at 20/20 Vision Center will likely recommend you receive the detailed visual field testing that only the Humphrey Field Analyzer can provide. Some of the reasons 20/20 Vision Center bring you this technology include that it is helpful in detecting and managing patients with optic nerve damage, as seen in ocular conditions like glaucoma or ischemic optic neuropathy. It can also help diagnose neuro-ophthalmic disorders, such as those associated with stroke or brain lesions affecting the visual pathway.
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, 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.
LipiFlow® and LipiView®
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.
i.Scription and i.Profiler
i.Profiler®plus does not only provide you a better prescription, it gives you access to an optimized individualized lens solution with i.Scription technology for improved color and contrast vision as well as improved night vision. i.Scription involves an innovative patented algorithm which combines the subjective refraction values with the i.Profiler plus ocular wavefront aberrometry data to calculate an individualized prescription to 1/100th of a dioptre – especially for lower light situations.
i.Profiler plus enables i.Scription technology through precise, automated measurement of your patient’s visual profile.
Conventional manifest refraction is performed in well illuminated rooms, leading to prescription values that work well in daylight situations. However, as the pupil expands in low light situations, the peripheral aberrations of the eye can lead to refractive shifts that make the conventional prescription no longer valid. i.Scription® technology is able to combine the information about peripheral aberrations provided by i.Profiler® plus together with manifest refraction, resulting in an optimized prescription to provide better day and night vision.
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).
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 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, 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.
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 to 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.
A pachymeter is a device that measures the thickness of the eye’s cornea. It is used before LASIK surgery, or eye evaluations, and helps determine if someone is developing Glaucoma.
Central corneal thickness (CCT) can be measured by ophthalmologists with a variety of instruments. Ultrasound technology is the most common method to measure CCT, and requires contact with the cornea. After a drop of anesthetic is applied to the eye, the pachymeter is gently placed on the cornea. There is another method that uses optical low – coherence reflectometry technology that might be more accurate and does not involve contact with the cornea.
