• Purpose: To look for a new method to resolve the lipcof pleats of patients with conjunctivochalasis without destruction of the pre-existing conjunctiva.

  Methods: Conjunctival zeta-plasty of the lower bulbar conjunctiva was tested in artificial models and in rabbits, and finally applied to four patients with conjunctivochalasis. In 3 cases the Z-plasty was performed by placing the central trunk of the Z in horizontal position, 4.5-5.5 mm from the lower limbus and 6 mm in length. The fourth patient had big pleats over the total length of the lower lid margin, and two smaller Z-plasties were performed at the same time one at the side of the other.

  Results: The lipcot pleats of four patients disappeared as did the previous symptoms of plerolacrima, epiphora, blurry vision and foreing body sensation.

  Conclusions: Z-plasty is an effective method for treating the symptomatic conjunctivochalasis. Its major advantage versus other methods is that it preserves the normal preexisting conjunctiva and its goblet cells.
