Advanced Technology for
Modern Eye Care

Your eyes are the windows to your overall health. They’re the only area in the body where your blood vessels, nerves, and connective tissues can be viewed directly, and problems that appear in the eyes could be an indication of disease elsewhere in your body. To get the best understanding of your eyes and health, we’re continuously investing in advanced diagnostic technology that give us an unparalleled view of your eyes. Our goal is to give you accurate information about your vision and health to ensure your eyes remain healthy and strong for many years to come. 

Optical Illusions: An Optometric Practice does this through innovative technology, ongoing staff education, and staying up-to-date on the latest eye care techniques. We believe that good ocular health and strong vision depends on a strong relationship between optometrist and patient. Let our Eye Doctors at Optical Illusions: An Optometric Practice be trusted members of your health care team.

In 2021, Optical Illusions: An Optometric Practice was recognized as a ‘Power User’ Practice by Oculus, a designation awarded to the highest level of advanced diagnostics clinics.

Retina Diagnostic

Optos Silverstone

The Optos Silverstone is the most advanced and innovative ultra-wide field instrument that combines swept-source ocular coherence tomography (OCT) and high-resolution retinal imaging. A combination of these imaging techniques in one device allows us to view your retina—the light-sensitive lining at the back of your eyes—in 3D and evaluate it in 3 different ways.

It’s effective for diagnosing and monitoring the early stages of diseases like glaucoma, diabetes, macular degeneration, and more. We’re proud to be one of the only practices in the country to offer our patients access to this specialized technology.

This test is quick, comprehensive, noninvasive, and can be completed while socially distanced, making it safe and invaluable, and can be life-saving in some situations which is why it is a required test at Optical Illusions. 

The Topcon Maestro 2 OCT complements the imaging we analyze from the Optos Silverstone. The Maestro 2 takes medical-grade resolution, noninvasive ultrasound images of the retina, macula, and optic nerve, giving us a better understanding of diseases found within these structures.

Images are input from the Maestro 2 into a normative database, which compares your eyes to others in your age group to ensure you are within normal ranges. These technologies allow us to build a timeline of the changes and progression to closely monitor for eye diseases like glaucoma, diabetes, and macular degeneration with great accuracy.

The Zeiss Cirrus 5000 OCT/OCT-A is one of the best devices that helps drive decision for ocualr disease. It provides repeatable high-resolution images of the retina, optic nerve, and anterior segment. The software analyses allow for efficient review of patient data and reliable progression metrics that help manage patients year after year with OCTA adding a layer of clinical insight far beyond structural OCT alone.

Glaucoma Diagnostic

Topcon Maestro2 OCT – Anterior Segment

The Topcon Maestro 2 OCT also can take anterior images of the Ocular Angle, the filtration system of the eye where the aqueous humor drains out of the eye. This allows our doctors to look for narrow angle or closed angles, which can cause a large increase in eye pressure, a precursor to Glaucoma.

The Maestro2 has the ability to perform pachymetry as well which measures your corneal thickness (in microns) and increase the accuracy of your eye pressures measurement.

A visual field test is a simple yet essential test for assessing your peripheral (side) vision. It allows our Doctors to determine if you have blind spots or vision loss due to eye diseases such as glaucoma or strokes.

The Virtual Field is a hands-free, virtual reality headset that allows you to sit comfortably anywhere in the office. If you’re familiar with the bulky older style visual field test, you’ll appreciate the convenience and comfort of this test.

When it comes to glaucoma, early detection is key. The Octopus Perimetry devices provide early glaucoma detection screening and offer fixation control while delivering accurate results in just 2.5 minutes.


Do you dread your eye exam because you want nothing to do with the “air puff test?” Don’t worry. Most people don’t like it! We use the iCare tonometer, a portable, handheld device that quickly, accurately, and comfortably measures the pressure inside your eye, called intraocular pressure (IOP). High IOP is often a characteristic of glaucoma, so taking accurate measurements of your IOP during every eye exam is an important step for testing for this serious disease. 

Since the iCare has disposable tips, it’s considered a safe and sanitary way to measure eye pressure, especially during the COVID-19 pandemic. And if you wear contact lenses, we can measure your IOP with your lenses in.

In addition to the iCare tonometer, we also use the Diaton tonometer. This handheld device quickly, painlessly, and accurately measures IOP through the upper eyelid, making it ideal for children and patients who wear contact lenses. 

Because it only touches the eyelids, this device is also considered one of the safest ways to measure eye pressure, especially while COVID-19 is a concern.

A corneal pachymeter is a device used to measure the thickness of the the cornea. This measurement is essential, especially for conditions like glaucoma. Thicker or thinner corneas can impact eye pressure readings, a key factor in diagnosing and managing glaucoma. The pachymeter helps our doctors get accurate thickness measurements, allowing them to better assess your eye health and determine the most effective strategies for managing glaucoma and maintaining optimal eye pressure. This information is crucial for making informed decisions about your eye care and preventing potential vision loss associated with glaucoma.

This is measured in our practices using an Ultrasound, or which our Maestro2 or Cirrus 5000 OCT Swept-Source technology.

Cornea Diagnostic

Oculus Pentacam AXL Wave

The Oculus Pentacam AXL Wave is the gold standard of anterior surface diagnostic imaging and allows us to evaluate your cornea, iris, ciliary body, and lens. It is used to diagnose and monitor corneal diseases like keratoconus and corneal ectasia while also allowing our Doctors to accurately fit specialty contact lenses and manage myopia.

In 2021, Optical Illusions was recognized by Oculus as a Pentacam Power User, a prestigious award granted by the company for being one of the top diagnostic practices in the country to use the Pentacam AXL Wave to identify innumerable ocular conditions in our patients. We are the first and only optometry practice to ever receive this recognition

Apple has been one of the most revolutionary technology companies in the last couple of decades. The EyePhotoDoc allow our Doctors to take advantage of an iPad Air’s 4K cameras and large liquid retina display to provide with high-resolution images of your eyes for diagnostic purposes.

This adapter integrates an iPad Air to our slit lamp microscope, making it easy to show you detailed images of our findings, upload your evaluation to the cloud, and airdrop, text, or email your photos directly to you.

Using the EyePhotoDoc, our Doctors can more easily diagnose and monitor issues with your cornea, conjunctiva, iris, eyelids, and eyelashes.

Dry Eye Treatment

Envision Lumecca Intense Pulsed Light (IPL)

Envision Lumecca Intense Pulsed Light (IPL) is a non-invasive treatment that treats dry eye by reducing inflammation in the meibomian glands of the eyelids. By gently heating and clearing blockages in these oil glands, IPL improves the quality of the oily component of tears, enhancing tear film stability and reducing dry eye symptoms. This treatment can lead to increased comfort and better overall eye health for those suffering from dry eye syndrome. Many patients can feel the difference with just their first session of Lumecca IPL, but some may require additional sessions for results.

Envison Forma Radiofrequency (RF) is a non-invasive, thermal pulsation treatment that treats dry eye by addressing blockages with the meibomian glands. It uses controlled thermal energy to melt and clear obstructions in these oil glands, allowing for improved secretion of the oil layer in the tear film. This helps stabilize the tear film and reduces dry eye symptoms, providing relief to individuals experiencing this condition.

Dry eyes can be uncomfortable, irritating, and even painful. Dry eyes are often related to meibomian gland dysfunction (MGD), a condition affecting the oil glands along the eyelids. Patients with MGD often have stagnant tears that can result in eyelid inflammation and discomfort.

Enter the TearCare System. This revolutionary MGD treatment applies consistent, targeted, and gentle heat to the eyelids while allowing you to blink naturally. During a relaxing, spa-like, 15-minute appointment, we’ll apply TearCare to your lids, where it’ll warm your meibomian glands, allowing us to gently express them, releasing blockages and stimulating better quality tears.

The Equinox Low-Level Light Therapy (LLLT), or cold laser therapy, is a non-invasive treatment that utilizes medical grade photobiomodulation light technology indicated for the application of diffuse periorbital heat to the eyelids. It treats conditions such as meibomian gland dysfunction (MGD), blepharitis, chalazion, styes, and rosacea.

This procedure is done in our office by our Certified Doctors and Technicians.
