The Leica Keratoscope is a ring illuminator used intraoperatively to qualitatively evaluate the corneal curvature of the eye for astigmatism. With the Leica Keratoscope the surgeon now has a cost-effective, integrated instrument to help assess the shape of the anterior surface of the cornea. This will aid him or her in making limbal relaxing incisions (LRIS) and positioning Toric IOLs.
