A Wavefront Analyzer is used to find out Corneal Astigmatism with Axis. The refractive, corneal and internal astigmatism are measured and analysed to achieve this.
Astigmatism is a vision problem that is caused due to irregular shape of cornea. The lens or front part of the eye (cornea) has an abnormal curve in case of astigmatism. Vision distortion, blurred or fuzzy images are the common symptoms.
