We designed an instrument to facilitate the operation for blepharochalasis. The skin to be excised is lifted into a fold and the latter than stabilized by tightly clamping the two layers of skin at its base with the new instrument. In this way the situation after excision can be simulated and the position of the future scar and the apposition of the lids against the globe can be estimated in advance and the fold can be adjusted if required. In addition, the compression of the skin decreases the tendency for bleeding.
