Abstract
Precise concentric, symmetric, and repeatable circular scoring (cutting) of Descemet's membrane is made possible by a handheld surgical ophthalmic device. The precision of the cut is provided by a stabilizing point on a stabilizing arm as well the anchoring insertion point at the limbus. Stabilization through the insertion point and the stabilizing arm provides a two-point fixation thereby establishing a cutting plane. The cutting plane allows for precise depth of cut whereas the rotating blade's consistent radius allows for circularity of the cut. The stabilization arm fixates on tissue, and is then removed when the procedure is completed. Consistent torque and contact pressure of the cutting blade is provided through rotational control via the depression of a button on a handle thereby removing the need to 'free-hand' the desemetorhexis.
