To ensure that you receive the highest-quality eye care possible, Focal Pointe pursues ongoing training in the most up-to-date treatment practices and continually invests in the most advanced proven eye care technology. The following technologies are in regular use in our West Chester office.
How does a Corneal Topography work?
The Medmont E300 Corneal Topographer is a computerized Video-Keratometer, using Placido rings to map the surface of the human cornea. The test is very easy to perform, simply requiring you to look at green light surrounded by red rings. These rings are projected onto the cornea and measured by the camera. The measurements are recorded by the computer and pieced together to form a topographical map of varying colors, resembling an elevation map of the earth.
What does a Corneal Topography check for?
By measuring the corneal surface, Dr. Lyons can diagnose and monitor many conditions such as astigmatism, keratoconus, pterygium, and other forms of corneal scars and irregularities. The results of the topographer can be used to assist in contact lens fitting, refractive surgery, orthokeratology and general assessment of the cornea.

How does an Iare Tonometer work?
The Icare tonometer is based on a new measuring principle, in which a very light probe is used to make momentary contact with the cornea. The measurement is barely noticed and often does not even cause corneal reflex. This is great news because the device makes IOP measuring a more pleasant experience on everyone.
What is an Icare Tonometer used for?
In general, a tonometer is used to measure the intraocular pressure of your eyes, or IOP for short. The IOP is one of the key measurements used for the diagnosis and evaluation of glaucoma. Patients typically have no warning signs of glaucoma until they have significant vision loss. For this reason, routine eye exams that include tonometry are essential to rule out early signs of glaucoma and protect your eyesight.
More about the Icare Tonometer
Icare technology has been proven accurate and reliable by several clinical studies which demonstrates the same accuracy and uncompromised reliability in its measurements. You can find more about Icare Tonometers at http://www.icaretonometer.com.

Optical Coherence Tomography (OCT)
OCT Macular Degeneration
How does an Optical Coherence Tomographer work?
Despite the precision and detail of the Heidelberg, an OCT only takes a few seconds to complete. You will need to look into the OCT camera, but nothing will touch your eyes and there are no puffs of air. The machine will complete the scan and process the results less than on minute per eye. This can usually be done without a dilation.
What does an Optical Coherence Tomographer check for?
An OCT can help in the detection of vision threatening conditions, such as diabetes, glaucoma, and macular degeneration. As time moves on, your vision may change from a retina condition that is difficult to analyze from a dilated exam alone. An OCT allows Dr. Lyons to view below the surface of the retina to detect issues earlier, preventing unnecessary vision loss.
More about the Heidelberg Spectralis OCT
Heidelberg Engineering has years of experience in optics, physics, and developing technology for imaging the finest details of the eye. Heidelberg Engineering products have assisted clinicians in detecting structural changes in advance of vision loss, raising hopes for new therapies to combat devastating diseases such as age-related macular degeneration and diabetic retinopathy.

Optical Lens Edging System
How does an optical lens edger work?
Once Dr. Lyons determines your prescription for glasses, our licensed opticians will order the “uncut” prescription lenses from our premium optical lab. An “uncut” lens is perfectly round and about the diameter of a hockey puck. This lens now needs to be cut down to the shape of your new frame and edged so the lens stays in place. This is where the edger takes over. A special adhesive pad is mounted to the “uncut” lens so the lens can be mounted in the machine. The edger then traces the outline of your new frame and stores the digital tracing in the computer. Once the edger verifies the measurements, a push of a button starts the edging process. Approximately 5 minutes later, your new lens is ready!

How does a Digital Retinal Image work?
The Nidek AFC-230 Pro Photographer is a sophisticated retinal camera that can take retinal images of most people without a dilation. You simply place your chin in a rest while the technician aligns the camera. Once your retina is in focus, you will experience a single bright flash. The image is instantly saved on the computer and ready for viewing.
What is a Digital Retinal Image used for?
By capturing an image of the inside of the eyes, Dr. Lyons can monitor the health of your eyes for the years to come. The image is invaluable since some eye conditions develop slowly over time. Imaging will be done with the presence of glaucoma, diabetes, macular degeneration, and other conditions. Even if your eyes are healthy, the image provides a “snapshot” of the health of your eyes when the image was taken. The image is incorporated into your chart and also sent to you to save for your records.
More about the Nidek AFC-230 Pro Photographer
The Nidek AFC-230 is one of the most advanced automated fundus cameras available today. Its sophisticated suite of automated tools make it the only device of its kind to offer detailed imaging with speed and reliability. You can find more about Nidek at usa.nidek.com.
How does a digital slit-lamp image work?
The Haag Streit IM900 is a sophisticated slit-lamp camera that captures still images and videos in a blink of an eye. You simply place your chin in the rest of the slit-lamp as you would during a normal eye examination. Dr. Lyons will adjust the light and then shoot away – without a flash! The image or video is instantly saved on the computer and ready for viewing.
What is a digital retinal image used for?
Conditions of the cornea often change very quickly, so photodocumentation can often help aid in the treatment progression of the condition. The images are also wonderful for education of our patients. Dr. Lyons often takes pictures of the eye to help explain how the eyes work. The image can be incorporated into your chart and also sent to you to save for your records at your request.

Visual Evoked Potential (VEP)
How does Visual Evoked Potential Work?
First, the technician will prepare your skin to be clean, dry, and free of any lotions or oils so the sensory pads can be placed on your head. After positioning the sensory pads, the technician starts the test. He or she may ask that you cover one eye at a time to record each eye’s response independently. Once the test begins, you will see a series of black and white patterns that appear to “flip” quickly over and over again on a computer screen. It is simply a matter of looking at the pattern for the duration of the test. The computer will capture the information and produce a report for Dr. Lyons to interpret.
What does a Visual Evoked Potential Check for?
The VEP technology in the Diopsys® NOVA device helps determine how your eyes communicate with your brain in a way that no other instrument or vision test can. Dr. Lyons will order this scan when he suspects early onset of glaucoma or macular degeneration. The VEP is also useful in optic nerve conditions, such as optic neuritis caused by multiple sclerosis, and other optic neuropathies caused by vascular issues. It is also extremely helpful in identifying those with amblyopia in all age groups.
More about the Diopsys Nova Testing System
The Diopsys® NOVA Vision Testing System provides Dr. Lyons with painless, non-invasive vision tests that utilize electrophysiological technology, including Visual Evoked Potential (VEP) and pattern Electroretinography (ERG). The purpose of these tests is to provide comprehensive information to better plan your treatment (if needed) and monitor the results. You can find more about Diopsys at www.diopsys.com.
Visual Field Analysis
How does a visual field work?
You will wear a patch over one eye and be instructed to fixate on a light on a screen. You will then be asked to click a button each time the instrument flashes a light in your peripheral vision. The visual field test typically takes anywhere from 5 to 10 minutes per eye to complete. The machine will then analyze the data and provide a detailed printout of the results.
What is a visual field used for?
A visual field test is an automated machine that detects blind spots in your peripheral vision. These types of blind spots can originate from eye diseases such as glaucoma. Analysis of blind spots also may help identify specific areas of brain damage caused by a stroke or tumor.
