Fish-eye lens is a special wide angle lens shooting all of the information within 185 degrees at the same time, but the image taken by it cause distortion. In order to fit for people's visual habits, the images need a correction. This article proposes a correction method of fish-eye lens based on projective reconstruction and verified the effectiveness of the method by the experiment.

Clinical Cases

We described two clinical cases of ortho-k lenses fitting in patients with “non-typical” corneal curvature/diameter ratio. The main goal was to acknowledge effective and safe use of this myopia correction method in patients with corneal diameter greater than 11 mm. Individual approach to each patient is the key to a successful and safe ortho-k lenses fitting.
