Your eye is like a camera. There are 2 structures that focus light – much like the lens of a camera. These 2 structures are the cornea and the lens. The cornea is the clear front surface of your eye that is located in front of the colored part of your eye (called the iris).
If you are a contact lens wearer – the contact lens sits on the cornea. Not all corneas are the same size. Some are more curved or “steep” and others are more “flat”. It is important to be properly fit for contact lenses by your eye doctor. If a contact lens is not properly fit, the contact can cause serious problems for the wearer – including corneal distortion, corneal swelling, corneal ulcers, inflammation and more.
A corneal topographer is an instument that can detect any corneal distortions caused from a contact lens. A contact lens may look and feel “fine” but, it can still be causing problems that you may be unaware of. Many times sleeping in your contact lenses or overwearing your contacts (wearing a 2 week contact for more than 2 weeks) can cause corneal distortions.
At Visionary Eyecare in Pembroke Pines, Sunrise and Davie- we perform a corneal topography on ALL contact lens patients. During the contact lens eye exam we use the corneal topographer to monitor the health of the patient’s cornea before fitting with a new contact lens and also to monitor the corneal health year to year for established contact lens wearers.
