• In this study we describe a method for simplifying the often frustrating and time-consuming task of dissecting conjunctiva from underlying Tenon's capsule during Gunderson flap procedures. Using gentian violet marks as a guide, a needle and two pairs of scissors are used in series to separate superior bulbar conjunctiva from the superficial layers of Tenon's capsule along a series of semimeridians. The technique provides the surgeon with important landmarks, reduces the risk of inadvertent buttonholing, and minimizes conjunctival retraction caused by uneven dissection of Tenon's capsule.
