Advanced Technology

Autorefractor

Autorefractor-testing - wylie vision careAn autorefractor or automated refractor is a computer-controlled machine used during an eye examination to provide an objective measurement of a person’s refractive error and prescription for glasses or contact lenses. This is achieved by measuring how light is changed as it enters a person’s eye.

This measurement is important for diagnosing certain eye conditions, such as astigmatism or corneal distortion, and it is very helpful for fitting contact lenses.

Autophoropter

auto phoropter - wylie vision centerThe autophoropter, is advanced technology used to measure a patient’s glasses prescription, strength of the focusing system, alignment of the eyes and muscle balance between the two eyes. It allows the doctor to control the entire vision examination process from a keypad on the desktop. The keypad also controls the digital eye chart that the patient views during the vision examination. The keypad electronically sends information to the phoropter head (the part of the machine through which the patient looks while performing the vision examination) to change lenses with a touch of a button. The doctor uses the keypad to perform different tests and make measurements used to come up with a glasses prescription for each patient.

Visual Field Testing

visual field testing at Wylie vision centerA 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.

An initial visual field screening can be carried out by the optometrist 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. For a more comprehensive assessment, special equipment might be used to test your visual field. 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 and the entire test takes 15-45 minutes. These machines can create a computerized map out your visual field 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 you 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. But, 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 exam of the retina.

200Tx device - optomap - Retinal Exam at Wylie Vision CenterOptos introduced ultra-widefield retinal imaging to support practitioners diagnosing, analyzing, documenting and monitoring ocular pathology that may first present in the periphery, and otherwise may go undetected using traditional examination techniques and equipment.

The 200Tx device, offers multiple wavelength imaging, including options for color, red-free, fluorescein angiography and autofluorescence. With simultaneous non-contact pole-to-periphery views of more than 80% or 200 degrees of the retina in a single capture, the 200Tx helps clinicians discover more evidence of disease and guide their treatment decisions.

 

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.
