We use the most up-to-date technology to ensure the best eye care possible. Here are some of the different types of tests and equipment you may experience on a visit to Next Level Eye Care.
Digital Retinal Imaging
We use cutting-edge digital imaging technology to assess your eyes. Many eye diseases, if detected at an early stage, can be treated successfully without total loss of vision. 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 our Jessup 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 allows our eye doctor to 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.
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.
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.
The auto-refractor is a digital refractor that works much the same way as the old fashioned phoropter. The big difference is that, instead of the doctor manually clicking through, asking you to decide for yourself which lens is best (which is especially hard when the lenses are very nearly the same!), the auto-phoropter is controlled electronically and measurements are done digitally. This not only shortens the amount of time it takes to decide which lenses will provide you your best vision correction (super helpful when trying to get your little one to stop squirming and co-operate with the process!), but also ultimately results in a more accurate eyeglass or contact lens prescription.
A non-contact tonometer (also knows as a “puff test”) measures the pressure in the eye. This is an important test for glaucoma screening, which is a serious eye disease that can lead to blindness if not treated. The puff of air measures the pressure in the eye by flattening the cornea in a non-invasive manner.
A lensmeter optimizes more accurately the spectacle lens type, and take measurements to verify the lens power. It also features a UV Transmittance Measurement Function which will tell how well your lenses are protecting your eyes from UV exposure.
The slit-lamp exam allows the doctor to see areas at the front of the eye. These areas include your eyelids, conjunctiva, iris, lens, sclera and your cornea. Other areas visible with the slit-lamp test are the retina and optic nerve. Optometrists in Jessup, MD use slit lamps to identify disorders, infection or any other complications offering a more interactive approach to documenting an eye exam.
We have both automated and manual phoropters.
Goldmann Applanation Tonometer
Setting the standard in tonometry
Haag-Streit offers a comprehensive range of tonometers and accessories. The AT 900 and AT 900 D Goldmann tonometers attach to the slit lamp and pivot in front of the microscope for the examination. The observation of the applanated surface is conducted only through the left eyepiece. Disposable tonometer prisms (such as Tonosafe) or reusable Goldmann measuring prisms can be used with either fixed or hand-held tonometers.
