Variations of corneal curvature as a result of use of soft contact lens

The corneal curvature was followed up in 10 patients wearing soft contact lenses for 1, 3 and 6 months. The axes of principal meridia were recorded for simplicity as the vertical and horizontal curve. The mean measurements after 1 month showed slight flattening in both meridia which was statistically non significant. Measurements after 3 and 6 months showed steepening in both vertical and horizontal meridia which were statistically significant [p < 0.01]
