On　the　basis　of　the　principle　and　process　of　LTK,　the　paper　puts　forward　a　partition,　load　and　restricting　solution　of　gridding　and　conducts　the　deformation　analysis　of　cornea　under　different　operation　parameters.　It　has　analyzed　the　deformation　quantity　of　cornea　and　diversification　rate　of　curvature　radius　under　different　parameters.　Through　analysis　and　contrast,　we　can　get　the　effect　degree　of　cornea　curvature　diversification　of　different　parameter　in　the　operation　so　as　to　make　certain　the　operation　effect　of　every　parameter　in　diopter　correction.
