There are many methods in orientation and stabilization of toric soft contact lenses. They are prism ballast, truncation, thin zone, back surface toricity and the combination of above. In this report we use the GNTC soft contact lenses. It is a prism ballast combined with inside toric for stabilization of toric axis. Clinically 107 persons (180 eyes) are fitted with this lens. Most patient 88.8% got satisfactory corrected V. A. (>1.0) and 93.3% wearing it comfortably. We find GNTC is a stable and easy fitting toric soft contact lens. In prescription the accuracy of toric axis is most important in visual result, but loose fitting will worse it.
