If another eye doctor dashed your hopes of wearing contact lenses because you have irregular corneas, it’s time to get a second opinion. The team at West Broward Eyecare Associates in Tamarac, Florida, uses the innovative sMap3D™ corneoscleral topographer to create precise maps of your corneas and create custom-fit contact lenses. Call the practice or schedule your next eye appointment online today.
sMap3D is an industry-leading corneal mapping device. It captures 1 million measurement points on your eye to create a highly detailed and precise map of the peaks and troughs of your cornea (the transparent front of your eye) and sclera (the white outer layer of your eye).
Your eye doctor uses the map of your eye to design custom-fit scleral contact lenses for patients whose corneal abnormalities prevent standard contact lenses from fitting them correctly.
The sMap3D scan takes only 3-5 minutes. You look into the device, which scans your eye from three angles: looking up, down, and straight ahead. The scan is completely painless, and nothing touches your eye, although your eye doctor does place a soft device over your eye to hold your eyelids open.
The sMap3D equipment combines these three scans to create an extremely detailed map of the surface of your eye.
A special type of contact lens, scleral lenses are custom-made for patients with abnormal corneas or sclera. They’re gas permeable lenses that have a larger diameter than conventional contact lenses. The large diameter allows the lens to rest on the sclera and vault over your corneal surface. Conventional contact lenses rest on your cornea, covering only your pupil and iris.
The team at West Broward Eyecare Associates prescribes scleral lenses if you have keratoconus. Keratoconus is a condition that develops when your cornea is thin and bulges out into a conical shape instead of a round dome. The cornea helps focus the light that enters your eye, and abnormalities like keratoconus can cause blurry or distorted vision.
You might also need scleral lenses if you’ve had a cornea transplant or have severe dry eyes.
Fitting a patient with scleral lenses used to require some trial and error to achieve the best possible fit. It would take several appointments as your eye doctor tried different shapes and sizes of lenses. However, sMap3D removes the guesswork and helps your eye doctor provide scleral lenses that fit correctly the first time.
