Intraoperative keratometry for toric IOL and LRI (optional)
Precise marking of the corneal steepest axis is important to optimize the surgical results with a toric IOL. Preoperative marking, however, can be inaccurate due to tilt of patient's face, rotation of the eye, incorrect placement of the marker, and so on. We have developed a new intraoperative keratometry to measure the power and axis of corneal astigmatism. This system can be used under the surgical microscope so that the steepest meridian is marked after the measurements. The measurement accuracy is within 5 degrees. In case of LRI, intraoperative keratometry can be used to confirm whether the amount of astigmatic correction is sufficient or not.
