Gulani Edge Delineator And Lifter
Current Techniques in Refractive Surgery
Arun Gulani, M.D.

Many refractive surgeons involved in performing the LASlK procedure, are also involved in correcting or enhancing previously performed lamellar refractive surgery cases. This new technique can be done at a slit lamp or under the operating microscope. The arcshaped end of the delineator has a lower edge polished to a sharp finish. The instrument sits snugly in the edge of the previous flap without much epithelial disturbance or wobbling. A simple arc movement delineates the entire edge up to the corneal hinge (Fig. 1). The bench-shaped lifter facilitates raising the corneal flap by maneuvering the horizontal plate under the delineated cornea with the vertical plate sewing as a rudder. A smooth transition along the delineated arc of the flap causes a uniplanar lamellar separation (Fig. 2). The flap can then be easily lifted with an atraumatic forceps revealing the previous stromal bed (Fig 3).
