Advanced Technology in East Plano
When you visit your eye doctor, you want to know that the optometry office has the best and most advanced technology to diagnose eye diseases and screen for possible vision problems. At Switalski Eye Care, we use the most advanced technology in all our eye exams and eye care services. Read about the different technologies we use during your complete eye exam.
Corneal Mapping
Corneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive technique used to image and map the cornea's surface curvature. The cornea is the eye's outer structure and is crucial for vision since it contributes approximately 70% of the eye's refractive power. Mapping the cornea's topography is essential for assessing vision quality.
This technique produces a three-dimensional map which is a valuable tool for ophthalmologists and optometrists. It helps in diagnosing and treating various eye conditions, planning surgeries like LASIK, evaluating surgical outcomes, and determining the fit of contact lenses. Corneal topography is an advanced form of keratoscopy. Unlike keratometry, which measures only four points a few millimeters apart, corneal topography analyzes thousands of points over the entire cornea. The process is quick, taking only seconds, and is completely painless for the patient.

Digital Retinal Imaging & OCT Scans
We use cutting-edge digital imaging technology to assess your eyes. If detected early, many eye diseases can be treated successfully without total vision loss. 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 our eye doctor 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 is 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 non-invasive, 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.
The optometrist can carry out an initial visual field screening 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. Special equipment might be used to test your visual field for a more comprehensive assessment. 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, taking 15-45 minutes. These machines can create a computerized visual field map 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 your 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. However, 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 retina exam.
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.
