A method for making an incision into the sclera of an eye includes the steps of (a) applying pressure to a portion of the surface of the sclera to flatten that portion of the sclera, (b) cutting an incision in the sclera with a linear blade along a line parallel to the flattened surface of the sclera, and (c) releasing the pressure on the portion of the surface of the sclera to allow the sclera to return to its natural curvature. By this method, the incision cut into the sclera in step (b) takes on a curvature which parallels the natural curvature of the sclera. The method can be carried out using a tool which includes (a) a generally smooth scleral flattening surface disposed within a flat, flattening surface plane, and (b) a generally linear incision blade having a sharpened free end. The incision blade is disposed generally parallel with the flattening surface and spaced apart from the flattening surface by a distance of between about 0.5 mm and about 0.8 mm.
