To provide our patients with the highest quality eye care, our practices are equipped with the latest innovative technology
NEUROLENS

NEUROLENS
Headaches and eye strain can often be caused by misalignment of the eyes. When your eyes are not working together, it puts extra strain on the brain to fuse the images together. This in turn can lead to overstimulation of the trigeminal nerve and result in symptoms such as headaches, eye strain, dry eyes, light sensitivity, neck and shoulder pain, and motion sickness.
The Neurolens is a revolutionary lens technology that utilizes contoured prisms to align the focus between the eyes. By correcting the misalignment, the Neurolens can drastically reduce or eliminate symptoms associated with overstimulation of the nervous system. The Neurolens is currently offered at Eye Theory Midtown.

DIGITAL PHOROPTER

DIGITAL PHOROPTER
Digital phoropters take refractions to the next level. The state-of-the-art system provides maximum precision by refining the prescription down to the single degree. Digital phoropters not only cut down on guesswork by the patient, but also enable the doctor to compare changes with the patient’s current glasses to create the most comfortable and optimal prescription. Digital refraction is the newest, most efficient method of prescribing glasses.

ICARE TONOMETER

ICARE TONOMETER
ICare ic100 tonometer revolutionizes the way we measure intraocular pressure. ICare enables the doctor to check eye pressure without the patient experiencing any discomfort by removing the need for air puffs or numbing drops. The proprietary technology utilizes a lightweight probe that evaluates deceleration, contact time and other motion parameters upon contact with the cornea.

OPTOS RETINAL IMAGING

OPTOS RETINAL IMAGING
Optos Ultra-Widefield Imaging captures a high-resolution image of the interior health of the eye without the side effects and wait time of dilation. Optos is the gold standard of retinal imaging as it is the only imaging system that captures a 200º field of view with a single image in less than a ½ second. Retinal imaging enables our doctors to diagnose and monitor the progression of ocular diseases including glaucoma, diabetic retinopathy, macular degeneration, and retinal detachments.

ZEISS CIRRUS 500
The Zeiss Cirrus 500 HD-OCT (Optical Coherence Tomography) produces micron level cross-sectional images of the retina, optic nerve and anterior segment of the eye. This allows for early detection of macular degeneration, glaucoma and retinal edema before symptoms appear. With Zeiss’ advanced software capabilities such as guided progression analysis, our doctors can track the most subtle structural changes in the optic nerve and macula.

OPTIKAM AUGMENTED REALITY

OPTIKAM AUGMENTED REALITY
Optikam optimizes prescription lenses by taking custom measurements based off an individual’s natural posture. The patented EY-Stick device captures 10 unique measurements including pantoscopic tilt, rear vertex distance and face form tilt to design a truly customized prescription lens. Optikam’s augmented reality feature allows patients to simulate the latest lens technology on the market.
