Keratorefractive Effect of High Intensity Focused Ultrasound Keratoplasty on Rabbit Eyes

Figure 2

Topography display of treated cornea (Sirius, CSO, Firenze, Italy). (a) Group 1 (therapy power, 1 W). (c) Group 3 (therapy power, 3 W). Tangential curvature of the anterior corneal surface before HIFU treatment. (b, d) Tangential curvature of the same cornea after HIFU treatment. It shows steepening in the central cornea and flattening outside. Sim-K: simulated keratoscope readings, K1: the curvature in the flat meridian, K2: the curvature in the steep meridian, Avg: the mean curvature, Cyl = cylinder, deg.: degree, D: diopter, OS: left eye, and tangential anterior: tangential curvature of the anterior corneal surface.
