All-in-one Autorefractor, Keratometer and Non-Contact Tonometer

The All-in-One AutoRefractor, Keratometer and Non-Contact Tonometer is an instrument used to quickly estimate a person’s refractive error. The numbers are used as a starting point to determine eyeglass and contact lens prescriptions.

This measurement is achieved by measuring how light is changed as it bounces off the back of a person’s eye. The automated refraction technique is quick, simple and painless. No feedback is required from the patient during this process.

The auto-keratometer-tonometer is used to determine the shape of the cornea. It does this by looking at the reflection of light off of the cornea at different points. These measurements are used to diagnose conditions such as astigmatism, keratoconus, corneal scarring and corneal distortion. A keratometer is also used to fit contact lenses as well. The combined measurements become a starting point in determining your spectacle and contact lens prescription.

Most patients remember the air puff from previous eye exams. The non-contact tonometer is used during your eye exams to measure your intraocular pressure. This testing is important in detecting glaucoma. The air puff test is much less invasive than other methods of measuring eye pressure. Other clinics use contact tonometers. Contact tonometers are probes that make contact with the cornea. This method requires the use of anesthetics. The air puff test is much quicker and more pleasant than alternate methods. It is the best way to ensure this very important test is performed.

Optomap Daytona Retinal Imaging

The Optomap Daytona Retinal Exam provides your doctor with an ultra-widefield view of your retina. An in-depth screening of the retina is key to ensure that your eyes are in good health. By performing such a thorough exam, we can detect any signs of disease, such as diabetes, glaucoma, macular degeneration and even cancer. Painless, the exam is quick and often does not require the use of dilation drops. Digital retinal scanning is highly recommended by our optometrists as part of your eye exam. The retina is the part of your eye that captures an image of what you’re looking at, much like film in a camera. Using our Optomap Daytona, retinal scans provide an image as unique as your fingerprint. Giving us a look at the health of your retina, these scans document your health for future comparison. Many eye problems can develop in the retina without warning, progress without symptoms. Images from your digital retina scan can be used to detect subtle changes in your retina over time, giving your optometrist the opportunity to discuss these changes and their implications.

Automated Phoropter

A phoropter is used during eye exams to determine a patient’s refractive error and prescription for glasses. Several powered lenses will be presented in front of your eyes.

By comparing sets of lenses, your eyeglass prescription will be determined. Automated phoropters are better than traditional phoropters (the “big glasses” you may have seen) because they can compare old prescriptions and new values, which reduces the risk of human error.

Visual Field Testing (Oculus Easyfield)

Visual field instruments test your peripheral and central vision, using an automated projection perimeter to shine a spot of light onto the back of the eye at predetermined locations and intensities. You are asked to press a button when you see the stimulus. Your responses are analyzed statistically and compared with a database of people your age, both with and without various conditions. A visual field is used for diagnosis and management of macular degeneration, glaucoma, and systemic conditions such as brain tumors and strokes.

Optical Coherence Tomography (OCT)

Optical coherence tomography (OCT) is a non-invasive imaging test. OCT uses light waves to take cross-section pictures of your retina. You will sit in front of the OCT machine and rest your head on a support to keep it motionless. The equipment will then scan your eye without touching it. Scanning takes about 5 to 10 minutes. OCT is useful in diagnosing many eye conditions, including: several macular conditions including age-related macular degeneration, optic nerve disorders, glaucoma and several retinal conditions.
