Technology

At Boneham Optometrist, we continually invest in technology so we can remain at the cutting edge of eye care. We have innovative technology that is used to detect eye diseases earlier, aid in treatment and enable accurate monitoring of progression. We have instruments that measure the cornea and sclera, allowing us to design customised contact lenses for conditions such as keratoconus, severe dry eye, pellucid marginal degeneration and progressive myopia. Read about the OPTOS, Topographer, OCT and SMAP below.

Optos Daytona Plus:

The retina is the name given to the light sensitive tissue at the back of the eye. As the eye is very curved, standard cameras have been limited to photographing just the central retina, which has the optic nerve and macula. Previous cameras could only capture 40 degrees, this shows us 200 degrees. The optos performs widefield imaging, so we can see the peripheral retina as well as the centre. This allows us to detect conditions such as retinal tears, choroidal nevus (freckles at the back of the eye), even if the there are no symptoms. This is becoming especially important with the increasing levels of high myopia, which comes hand in hand with increased risk of eye disease.

Corneal Topography:

The cornea is the clear tissue at the front of the eye, the role of the cornea is to focus a clear ray of light onto the retina. If the shape of the cornea isn’t a sphere you have what is known as astigmatism. The corneal topographer allows us to map the front surface of the cornea and measure astigmatism. It also allows us to detect conditions such as keratoconus and pellucid marginal degeneration. We also use the topographer to guide contact lens design for eye disease and for orthokeratology.

Optical Coherence Tomography (OCT):

OCT is used on both the front and back of the eye. It is a non-invasive imaging test using light waves to take cross-section pictures of your eye. OCT is used for macula and optic nerve conditions such as macula degeneration and glaucoma. We also use OCT to measure the gap between specialty contact lenses and the eye.

SMap 3D:

This is our newest piece of technology which we purchased in late 2019. The sMap is revolutionary, prior to this machine we were only able to get half the information on the shape of the eye. Standard instruments measure 11mm when we were using lenses that were 16.5mm. With this instrument we can measure the shape of the white of the eye, which is where the lenses rest. Many of our patients have BOTH corneal and scleral astigmatism, so we need to measure both! Having a lens that can correct this means the lenses are more stable, giving better safety and comfort for our patients with scleral lenses.
