As specialist contact lens fitters, the equipment we use is vital in determining the best lenses for your needs. Some items, such as the Non-Contact Tonometer and Visual Field Screener, you may already be familiar with whereas other items are what set us apart from the competition.
We spend as much time as is necessary with each of our patients to ensure our recommendations are perfectly tailored to your needs, and this includes a thorough and detailed pre-screening procedure for everyone.
You will find:
3D OCT Scanner (Ocular Coherence Tomography) & Retinal Camera
If you are a regular sight test patient, you may already be familiar with Retinal cameras. These cameras take a two dimensional photograph of the internal structure of your eye, allowing to Optometrist to identify certain diseases of the eye and refer you for appropriate treatment. Our 3D Scanner also has this function but more importantly, with a 3D generated image of the most vital structures within the eye, our Optometrists can detect these diseases before they are visible on the 2D photograph, allowing for early diagnosis and treatment.
Thanks to the development of this camera, thousands of patients have been referred for early treatment of conditions which, if left longer, could result in complete loss of vision.
Tonometers are used to detect signs of glaucoma by measuring the intra-ocular pressure of each eye with a small pulse of air. When diagnosed early glaucoma is fully treatable, which is why all of our patients over the age of 40 are routinely screened.
The Auto Refractor records a precise measurement of your error of vision with or without glasses or contact lenses, as well as measuring the curvature of the front surface of your cornea. We screen every patient at every appointment, as this will give us a good idea if any adjustments are likely to be needed.
Visual Field Screener
This is the second part of our glaucoma screening process. Another early warning sign of this disease is failing peripheral vision, and this screener checks between 26 and 136 points depending on the loss detected, and can also be used for mapping visual loss that has already been detected previously.
The measurement that are taken with the Auto Refractor are transmitted automatically to the Phoropter in the testing room. If you’ve had your eyes tested before, you will be familiar with the trial frame (the hollow plastic glasses) and lens inserts that the Optometrist uses to determine your visual correction. This instrument has all of those lenses already built into the design, ensuring an accurate and efficient prescription.
Being able to fit Ortho-K and Keratoconic lenses is part of what makes us specialist, and it wouldn’t be possible without this instrument. By taking a 3D topographical map of the front surface of your eye, our Optometrists are able to simulate the fitting of different lens types. We then send the file over to our suppliers, who manufacture the lenses specifically to the measurements of your cornea.
Used to view the cells at the back of the cornea and measure corneal thickness, this instrument is usually found in some Eye Hospitals. It takes a 400x magnified image, which allows our Optometrists to assess how much oxygen is being transmitted through to the cornea. This means that we can easily detect if your current contact lenses are restricting the flow of oxygen before the cells become starved.
