ATLAS CORNEAL TOPOGRAPHY SYSTEM

IIn an effort to expand and improve on the quality of care and services we bring to our patients, we have added a new state-of-the-art instrument to our office. It’s called the Humphrey ATLAS Corneal Topography System.

This instrument is currently the most accurate method of examining the front clear surface of the eye. It is a computerized photographic device that measures a large area of the corneal surface and provides a topographical map of the corneal shape.

The cornea is the curved window of the eye, and when healthy, it is completely transparent. It is an important part of your eye’s refraction system and directly influences how well you see. With the Atlas, we can get a complete picture about the state of your cornea, whether it’s steep or flat, and indications of corneal disease.

Though this safe, non-invasive procedure only takes seconds, the ATLAS accurately measures thousands of points on your cornea. Aside form establishing important baseline information, this new instrument is highly useful in several other ways. It assists us in evaluating patients for refractive surgery, such as RK, PRK, or LASIK; in detecting and monitoring corneal diseases; and in prescribing contact lenses and monitoring the fit of the lenses.

The results from this procedure are presented to your Doctor at Triangle Eye Care in the form of colorful topographical maps, similar to those depicting peaks and valleys of land surfaces, and easy for you to understand. In cases where a referral or consultation is advised, this sophisticated computerized instrument allows your Optometrist to send the results of your examination to other eye professionals via the Internet.

Corneal Topography and Contact Lenses

The cornea is the clear window on the front of the eye and is made up of many different curvatures. It is necessary to understand these curvatures in order to properly fit and prescribe contact lenses or spectacles. Until now, instruments used for measuring the curvature of the cornea were only able to measure a small area in the center. Contact lenses, on the other hand, cover a much larger area of the cornea. The computerized Corneal Topographer uses thousand of data points to measure a wide area of the cornea. Various printout displays help us to choose contact lenses that fit properly and feel comfortable. The Humphrey Corneal Topography System is another example of the advanced technology we offer our patients.
