Technology – Advanced Eye Care

Dr. Ali uses the most up-to-date technology to ensure the best eye care possible.

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.

Octopus 600

Our Roselle eye care experts use the Octopus 600 visual field test in our office. The Octopus 600 performs standard white-on-white threshold testing in just 2–4 minutes in the central visual field.

Tomey Auto-refractor/Keratometer

An 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.

We carry the Tomey Auto-refractor/keratometer in Roselle Eye Clinic.

Digital Acuity System

Modern versions of Digital Acuity Systems are built through computer monitors. This enables the ability to feature a large number of vision tests, whether its letters, patterns, or colors. The slides can be changed with the use of a remote, making the system simple to use.

iCare Tonometers

iCare Tonometers are used for easy, accurate and patient-friendly intra-ocular pressure measurement, which is used for glaucoma screening. iCare tonometers are based on unique, patented rebound technology, in which a very light and small probe is used to make momentary contact with the cornea. The Icare tonometer is based on a proven accurate measuring principle, in which a very light probe is used to make momentary and gentle contact with the cornea. The measurement is barely noticed by the patient. The device not only makes IOP measuring a more pleasant experience on all patients, but it is also an important break-through for succeeding with non-compliant patients (i.e. children and dementia patients).

Digital Pupilometer

A digital precision is an optical instrument used to measure the distance between a patient’s pupils. This number is used when fitting a patient for a pair of eyeglasses.
