Corneal Topography Screening, Explained

Corneal topography screening may sound like a pretty intimidating procedure, but it’s actually a very simple process that’s important for maintaining healthy eyes.

But there are a few things you should know first before undergoing the procedure. Here are some common questions:

Why are my corneas important?

Corneal Topography Screening

A cornea is the first place light touches as it hits the eye, and it is responsible for almost 70 percent of the eye’s refractive power. It’s made of transparent tissue, and, perhaps as equally important, it covers the eye’s iris and pupil.  The Cornea is the area that a contact lens usually rests on.

Unfortunately, corneas are very delicate. Disorders, infections, allergies, and pink eye are just a few of the common problems people can run into that can cause abnormal changes in the cornea and impair your vision.

How can corneal topography screening help?

Corneal topography screening can detect misshapen or warped corneas caused by the problems in their early stages, and help determine the best course of treatment for you. The test essentially creates a detailed map of your cornea’s shape, which helps our Carrollton optometrists decide whether refractive surgery or LASIK surgery is appropriate for you.  This map can also determine if there is an underlying corneal problem like keratoconus or Fuch’s dystrophy that can affect your vision.

Regular screening is important, because the further ahead of time irregularities are detected, the better your chances are for successfully treating them. Since corneal problems can arise even from every-day encounters like putting in contact lenses, timely check-ups for your eyes are key to keeping your corneas and vision healthy.

Is the screening process invasive?

Not at all. An advanced digital camera scans your eye and creates the map within a matter of seconds. All you have to do is keep your eyes open for the camera to take pictures. The procedure is completely non-invasive and pain-free.
