The development of the single point cam guided cornea trephine frees the cornea surgeon from always cutting a round recipient window perpendicular to the visual axis of the eye. This new trephine allows for any angle of cut relative to the visual axis of the eye and any shaped window, be that window round, ellipse, oval or "other than round." Full development of the technique lies in the future with the development of more complete topographical measuring techniques and the integration of the measurement into a computer program wherein the computer controls the indexing of the blade cutting the recipient window and the angle of the blade while the blade is making the incision.
单点凸轮引导式角膜环钻的发展使角膜外科医生无需总是垂直于眼睛视轴切割圆形的植床窗口。这种新型环钻允许相对于眼睛视轴以任何角度进行切割，并可制作任何形状的窗口，无论是圆形、椭圆形、卵形还是“非圆形”。随着更完善的地形图测量技术的发展以及将测量结果整合到计算机程序中，该技术的全面发展仍有待未来实现。在计算机程序中，当刀片进行切口时，计算机可控制切割植床窗口的刀片的分度以及刀片的角度。
