[New surgical methods for punctal occlusion of severe tear-deficient dry eye and its outcome].

Abstract

Although several surgical methods for punctal occlusion have been reported, it is difficult to obtain complete punctal occlusion in all cases since recanalization of the punctum often occurs after the operation. In this report, new surgical procedures to obtain sufficient occlusion of punctum are introduced and the outcome of the present method is compared with that of previous methods.
